There's Something Behind That
Rotary tools were first introduced to the market by Dremel, the company established by Albert J. Dremel in 1932. The Dremel's successful activity drew the interest of Bosch company that acquired the brand in 1993, which turned out to be for a good reason. Anyways, we picked the cordless rotary instrument called Dremel 4000 for our review. A solid plastic body with rubber covers allows comfortable and reliable gripping. The Dremel 4000 is equipped with a sliding power switch, spindle lock button, and a speed control dial. In addition, the model features the metal loop that enables convenient storage and comes in handy for suspending the tool and operating the chuck on a flexible shaft freehand. Also, the tool features removable caps for easy brush replacement and vents in the body for preventing the motor from overheating.
For Various Tasks
The Dremel 4000 is driven by the 1.6A electric motor. We assume this power to be sufficient for handling tough materials and providing a pretty long continuous tool operation. The spindle speed ranges from 5,000 to 35,000 RPM with the tool offering several speed settings thanks to the control dial on the bottom. With the total of seven available speeds, there is a speed indicator on the dial with RPM values indicated as thousandths of the actual speed: 5, 10, 15, 20, 25, 30, and 35. Gaining such a smooth speed control, you'll be able to process plastics, organic glass and soft metals including the precious ones. Running at full speed, the work equipment can excellently drill, cut fine metal pieces and hard wood, and perform timber grinding, rabbeting and engraving. Well, the tool's capabilities impress and we recommend choosing this tool if you seek a powerful and efficient accessory to deal with bitty items.
Now That's Quite a Kit
Most Dremel tools are distinguished by the branded EZ Twist feature. It consists in using the inner surfaces of the tool's nose cap functioning as a wrench that allows you to loosen and tighten the collet manually without a standard wrench. Nevertheless, using this wrench is preferable for jobs involving soft materials. With that, if you need to cut or drill into something with the 4000, it is highly recommended to tighten a collet nut with a wrench. During our review, we found that the tool switch prevents the collet lock button from pushing when it's set to ON position. This is a smart feature as it saves you an unintentional collet locking as you run the motor to keep the tool internals safe.
Pushing The Limits
The flexible shaft you can find in the box will expand the reach of the tool collet and let you work with the highest accuracy, keeping your hands free from holding the tool.
No Wiring At All
The next pick in our review is the Dremel 8220, one of the cordless rotary tools. Taking a look at this model, it's easy to notice its bulkiness and heaviness. Indeed, the tool's weight is 3.5 lbs. But then, the model is intended for quick performance of tasks rather than longtime operation. This includes doing a polishing on an elevated spot or cutting on an off-the-grid site. Indeed, there's a multitude of jobs where this cordless tool turns out to be useful.
When looking at this Dremel model, you will surely notice the rubbery grip designed so that the tool cannot slip off your hand. In regards to the controls, we'd like to point the collet locking button and the sliding speed switch. Another useful external element the tool features are the battery charge indicators, as well as a metal loop for hanging the tool. The package includes the battery, charger, and attachments for cutting different materials.
No Long Waiting For the Tool Charging
Despite the battery-powered operation, the tool's capacity is on a par with corded models yet it can't boast a long run. The tool features a 12V motor powered by the 1.5Ah battery. Once charged, the tool works 15 to 30 min, still, this period depends on the job complexity and use intensity. When the tool battery drains, it can be fully charged in about an hour and you may take a break or have a lunch meanwhile. The Dremel 8220 offers chuck rotation speeds ranging from 5,000 to 30,000 RPM and features the sliding switch that provides 6 speed settings: 5,000, 10,000, 15,000, 20,000, 25,000, and 30,000 RPM. This feature allows setting the speed in line with your needs to achieve the best results in every task you perform with the tool. Overall, the tool's speed range is sufficient for handling most typical materials from plastic and glass to masonry and metal. Also, the tool can be successfully used for engraving precious metals at medium speeds.
No Worries of the Tool's Heaviness
It's certain that mobility is the greatest plus of the Dremel 8220. However, this model has other benefits and the EZ Twist™ Nose Cap is one of them. It was designed to tighten and loosen the tool collet nut manually for a tool-free bit change. This nose cap is interconnected with the collet and serves as a wrench, which makes it available anytime you change accessories. Another nice thing is that the model is capable of using a flexible shaft (optional) and is fitted with the metal loop. Thus, you can get the tool secured and get your hands free to use the collet. The tool box contains 28 attachments for various applications and 1 multi-purpose attachment. The attachment is an adjustable cap that allows you to set the depth for the collet travel that's super convenient for drilling or cutting jobs. Similarly to most Dremel power tools, this one is shipped with a box for a convenient tool storage and instant access to the kit.
So, rest assured this Dremel model gives quite an advantage to people working on sites where extenders are too clumsy.
Choose Your Battery
This model is also available with the two-battery kit, so we recommend buying this version to swap batteries and avoid waiting until the tool gets charged. Or, you can get a more powerful tool if your job is challenging.
Allowing You to Work for Hours
Let's look at the rotary tool by WEN, the company that pioneered the manufacture of power tools. This is the WEN 2307, the corded model that weighs only 1.1 lbs. The tool's body is all-plastic and has no rubber covers or inserts. Thus, we advise using rubberized gloves to prevent the tool from slipping off your hand. Going on to the controls, we find an ON/OFF switch, speed adjustment dial and a spindle lock for attachment change. Also, there's a metal ring for hanging the tool, though it is not attached firmly to the unit case. For your convenience, the motor brushes are easy to replace thanks to quick-removable caps on both sides of the tool.
For Household Chores
The WEN does a good job when it's used for domestic jobs. The 1A motor drives the spindle at 8,000 to 30,000 RPM speeds. The speed can be changed using the wheel featuring the numbers from 1 to 6 and the “max” symbol. Turning the wheel up to the “max” point, you'll hear a snap notifying you of setting the top speed. As you've probably noticed, the lower speed limit of this tool is higher than the average one of other models. As a result, the tool is inconvenient for jobs requiring chuck rotation speeds less than 8,000 RPM. Though in general, the smooth speed adjustment allows handling both soft and hard materials such as glass, plastic, wood, and other materials. It's worth mentioning that the tool is compatible with 3/32" and 1/8" collets.
So Many Attachments That It's Hard to Count Them
Probably, the first thing among those we were pleased to notice about the tool's usability, is its 6ft power cord. The cord length is enough for a comfortable use of the tool in a workroom. Even more to that, you can attach a flexible shaft and suspend the tool on some purchase or hanger for greater comfort. For easy accessories replacement, the WEN comes with a wrench that features a screwdriver tip on the end. This tip is made for unscrewing brush caps of the motor for maintenance or replacement. With the package, you'll get a cool set of accessories that counts 100 pieces total for performing all kinds of operations you may be tasked with. The 54 sanding disks with different grit count are surely an impressive kit. Also, you will obtain 20 cut-off wheels to deal with a variety of materials. A small downside is that such a kit comes without a carrying case, but this is OK for the price. Moreover, the tool will take less space in your work cabinet or drawer if stored without a case.
Summing up, we recommend buying the WEN 2305 to those needing a medium-duty tool with a multipurpose set of accessories.
What About More Advanced Package?
WEN also offers the Dremel kit that includes a case and a flexible shaft for more comfortable working.
2 in 1
The next item in our review list is the Ubante U300, an electric-powered Dremel tool. Just like the most corded power tools, it has a plastic body without rubber pieces or inserts, which makes it more slippery in your hand. The U300 body accommodates a few ventilation holes to ensure a proper motor cooling under high loads. The controls feature the spindle lock button and the slider that adjusts the rotation speed with the tool turning on and off as a secondary function. Next to this slider, there's a scale that indicates the tool speeds. This Ubante model is equipped with a cord that's long enough for you to work comfortably in your garage or work shed. Additionally, the tool is fitted with the loop, which allows you to mount the unit on a stand and equip with an optional shaft extension.
Lower Power But Higher Speed
Now, let's move on to the tool performance. The tool is driven by the 0.7А energy-efficient motor that ensures a proper tool operation within the specified limits. The electric motor used features a sealed ball bearing for better cooling, smoother and quieter performance, thus ensuring a longer tool life. Despite a comparatively low motor capacity, the tool is able to deliver the shaft speed ranging between 10,000 and 37,000 RPM. The lower speed limit is rather high, hence the tool performance for machining such materials as plastics or plexiglass is not that good. On the other hand, the upper speed is excellent for performing such operations as grinding, polishing, and cutting. What is more, you can use the Ubante as a router and our next review paragraph is dedicated to this application of the tool.
A Smooth Turning On of the Tool
The variable speed control with ON/OFF function stands out among useful and convenient features of this Dremel tool. Unlike tools with dedicated start and speed controls which allow starting the tool at high speeds by accident, with this type of control you always start your Dremel at a low speed. This smooth start is believed to prolongs the motor duty cycle. A small disadvantage of the Ubante U300 is its dangling suspension loop. Though it does not bring much of a discomfort, it can still snag on something by accident.
When considering the tool accessories we'd like to highlight the router attachment. Having connected it to the chuck, you can adjust the bit protrusion and use the tool for rabbeting, chamfering or grooving. The package features 23 attachments including cutting wheels, sanding drums, drill bits, etc. Additionally, the package offers 5 collets, 2 motor brushes, and a wrench. By the way, the wrench features the flat tip that can be used for removing brush caps or disassembling the tool.
To sum up, we can recommend this Ubante model to those handling hard materials, as the speed range it offers is perfect for that.
Keep Safety In Mind
Operating this Dremel tool, use safety goggles and hearing protectors. Also, don't forget to clamp the workpiece in a vice rather than holding it in your hand.
Black & Decker RTX-B
Nice To Hold
Finally, it's the Black and Decker RTX-B turn to appear in our review, which is one of the most affordable Dremel tools. The tool is made corded and thus lightweight, weighing just 1.1 lbs. Owing to the fact that the tool case features rubber covers, it can be comfortably operated without gloves. There's also a textured rubber molding beneath the collet to provide a firm grip. When examining the RTX-B exterior, what we saw was a spindle lock made as a sliding switch. Near it, we noticed an On/Off switch and a speed adjustment wheel. Near the tool bottom, we found the metal hanger that serves for hanging the tool for using a flexible shaft.
Crushing Power for Tough Materials
This Black & Decker model does its job brilliantly thanks to the 2А motor, which capacity is exciting. Such a powerful motor offers longer continuous operation of the tool and makes it capable of enduring higher loads. However, such power comes at a price of a comparatively narrow speed spectrum that lies within the 12,000 - 30,000 RPM range. Because of this fact, we recommend you to keep the tool away from soft materials. With that, machining of stiff pieces is totally allowable with the tool. You can set the speed to 12,000; 24,000; or 30,000 RPM using the control wheel with “L”, “M”, and “H” marks respectively. What is more, the wheel clicks on each setting, so you can adjust the speed to the touch, even in total darkness. Overall, the instrument is suitable for strong and medium-density metals, including precious ones.
Super Easy Attachment Change
When it comes to usability features of this rotary equipment, the Flip-Lock™ spindle lock comes to the fore. To change an accessory, you don't need to hold the button instead you just flip the lock and have both hands free for a faster changing. It is useful for you to know that the spindle lock is combined with the On/Off switch in the following way. When the switch is in the ON position, the lock can't be pushed. In such a way, the manufacturer prevented the tool from accidental spindle locking resulting in a damage of the tool internal elements. As regards the model outfit, you will find an attachment and 5 sanding drums in the box. Also, the kit includes the wrench that can be used as a screwdriver, so you can quickly replace the motor brushes without additional tools. Also, it is nice to see the Black and Decker bag for a convenient storage of the tool and attachments.
In general, this Dremel tool will be a nice choice for beginning users that aren't ready to buy advanced pricey tools.
Need a Mini Drill?
Additionally, the tool comes with the keyless chuck that accepts drill bits ranging from 1/32" to 1/8" in diameter, so you can use the Black & Decker RTX-B for drilling tasks.
What is a Rotary Tool?
Probably, each of us has ever used a drill or angle grinder for perforating or buffing wood, concrete, or metal. But, what to do when a project is small and requires a tool more precise than a grinder or drill? In this case, a rotary tool is the best. Drilling holes up to 1 mm, polishing tiny pieces, engraving, and carving wood, glass, or plastic, that's what rotary tools can do perfectly.
Rotary tools, often referred to as dremel tools, are similar to engravers and feature cylindrical bodies with an electric motor inside. The motor is able to deliver high speeds for accurate materials processing. Dremel tools are usually used by workmen who engrave, grind, polish or cut various ware and may also prove useful for jewelers. Generally, dremel tools are irreplaceable for fiddly jobs.
If you deal with engraving only, consider our review on engravers that features vibrating and rotary models. If you are more into polishing and grinding, choose one of the die grinders driven by electric power or compressed air.
What Features to Compare
Today, dremel tools are available in electric and pneumatic versions. Electric models, in turn, are manufactured corded and cordless. Hence, you have to mind the place you are about to work in. If you mainly work at the table, it would be rational to choose a corded model. The corded models feature reinforced cables which length is sufficient to give you enough room for moving comfortably around the table. Moreover, you'll have no troubles with depleted batteries. As for the cordless models, they commonly come with Li-ion batteries and are more suitable for places with no power supply. Cordless models are for the most part heavier than corded analogs but their mobility and ability to work off the grid make a difference. Using a cordless tool, you have no troubles looking for a socket and dragging extenders across your worksite. Pneumatic tools are expedient for large-scale operations typical for workshops. Yet, the air-operated dremel tools require careful maintenance and are pretty noisy, so it's not the best choice for households.
The motor capacity and torque are the main performance criteria of a dremel tool. As for a motor capacity, it's worth noting that this parameter greatly affects the continuous operation time of the tool making more powerful tools capable of working longer than ones with lower motor power. The speed is vital for the model performance as the higher the rotation speed of the tool chuck, the finer and more precise you can engrave, cut or grind materials with the tool. Besides that, the chuck speed adjustment can be of much use as some materials can't be machined at high speeds. It's better to pick a tool with a smooth speed adjustment as it enables the tool to work with a wider range of materials. However, if you deal with metal or hardwood, go for a model with 5 or fewer speeds, since hard materials are mainly machined at a high speed. Meanwhile, soft materials are better to handle at a medium speed thus making a smooth rotation speed adjustment a must.
As concerns the convenience of a Dremel tool, the weight is one of the most significant aspects. Tough jobs usually take a lot of time and using a heavy tool makes you feel tired sooner. That is why some rotary tools come with a flexible shaft for their chucks. Using such accessory, you can suspend the tool in a vertical position and manipulate only the chuck attached to the shaft. This solution proves its edge in hard-to-access places. Also, dremel tools can be paired with foot pedals similar to those of sewing machines. Such pedal allows you to smoothly adjust the unit speed right on the fly.
The tool chuck, or to be more precise, the way it holds attachments is also important. Dremel tools feature either keyed or keyless chucks and the latter allow faster attachment change giving you more time for the job itself. Also, it is useful to know what accessories are included in the package of your tool and if the case for carrying the entire kit is available.
Q: What are rotary tools used for?
A: Equipped with standard bits and accessories, rotary tools are capable of performing such operations as cutting using special wheels, shaping, hollowing and carving using cutter bits/points, engraving using engraving bits. These tools also can do grinding and sharpening using grinding stones, sanding using bands and drums, polishing and cleaning using polishing wheels, and drilling with drill bits. Dremel tools can be applied to a pretty wide range of materials like metal, wood, plastic, glass, stone, and even dog toenails. Dremel tools may come with carbide and steel bits for handling softer materials, whilst tungsten-carbide and diamond bits are good for harder materials. There are Dremel attachments, such as a router attachment that allows edging and routing wood and plastic.
Q: How to hold a Dremel tool?
A: There are at least 3 ways to hold your tool.
1. The way you hold a pen. The tool grip is at the base of the shaft.
2. The way you hold a knife. The grip is the middle of the shaft.
3. With both hands. Hold the tool along the length of the shaft.
Q: How to change bits and attachments?
A: To change a bit/attachment, you need to do the following.
1. Hold the spindle lock button.
2. Loosen the collet nut with the wrench.
3. Change the bit by removing the current bit, and inserting a mandrel/spindle of a new bit or the bit itself into the collet. A wheel usually comes with a mandrel you attach, while bits are permanently attached to spindles.
4. Tighten the collet nut with the wrench and make sure the bit doesn't wobble. Release the spindle lock.
5. If your Dremel has the EZ Twist™ mechanism, you can change the bit without a wrench, by simply loosening the collet and changing the bit.
Q: How can I repair my Dremel tool?
A: Before repair, make sure to check the following things.
1. The motor brushes aren’t worn out.
2. The power outlet or batteries are intact and functional.
3. The interior of the tool is free from debris and sawdust.
4. The tool is used according to it’s intended purpose (and is not overloaded).
5. Only properly sized accessories or attachments are used with the tool.
Once you have checked those things, check if your model is still covered by its warranty. If it is, call Dremel and ask for service.
Surely, you can try to fix the problem yourself by following these steps.
1. Disconnect the tool from the power source.
2. Remove the plastic cap on the tool head.
3. Depending on the model you use, there will be screws securing the shaft. Remove these screws with an appropriate screwdriver.
4. Access the tool internals to address the issue.
5. If the tool shaft does not spin up, the most probable cause of the problem is that the coupling is worn down (the little ring between the shaft components). Always check this coupling for integrity.
