About the Product
The Dremel 4300 is the first Dremel rotary tool to allow tool-less and collet-less accessory changes with the inclusion of the three-jaw chuck. The chuck accepts all Dremel accessory shank sizes for fast and convenient accessory changes without ever using a wrench. Featuring the all new Pivot Light, your projects are well-lit with an optimum line of sight since the light pivots to direct illumination where you want it. Experiencing the full range of Dremel rotary tool applications is easier than ever because the 4300 offers our most powerful motor with built-in variable speed and electronic feedback circuitry. And the slim, ergonomic body design provides a comfortable 360-degree grip zone no matter how you hold it for extended ease of use.

The Dremel 8220 variable-speed cordless rotary tool kit offers the highest performance and versatility of all Dremel cordless rotary tools. The strength of its motor facilitates maximum performance at all speed levels. In fact, with its 12VMAX lithium-ion battery technology, the Dremel 8220 has a 33% longer run-time than the Dremel 8200 cordless rotary tool when cutting screws.

What customers say about "Key Specs"
Dremel 4300-5/40 High Performance Rotary Tool Kit
  • The new speed control is semi-protected thus preventing accidental speed changes (nice improvement) also the speed control is separate from the on-off switch, also an improvement I think.
  • Very happy with this set ! It works perfectly .. love the variable speed .. use it often to do my wood carvings.
  • When my 40-something year old Dremel variable speed rotary tool finally gave out after, well, 40 years of nearly ceaseless use without so much as a brush change it was time to get serious about a replacement.
  • This drill has mass and power. It is variable speed and extremely comfortable to use.
  • Lowest rpm is unstable and randomly revs.
Dremel 8220-1/28 Cordless Rotary Tool
  • Separate power and variable speed switch. Variable from 5-30k.
  • EZ twist collet lock (no need to carry around wrench).
  • It has low level variable speeds which are very nice for especially slow and deliberate work.
  • I like this unit for the power/speed, which is fully adjustable via a slider switch.
  • I use this at work to grind dog's nails. I am able to set the speed where I need it and then turn the tool on/off at the separate switch. This is a huge time saver!

What customers say about "Size & Weight"

  • Only thing that I wish was better is the weight, it is some what heavy for doing very detailed work, that is why I brought the flexible shaft accessory.
  • Speaking as a woman with physical disabilities, it's the ideal rotary tool for me, because I don't have to put my weight behind it.
  • The rotary tool performs as expected, smooth, well balanced, easy to control.
  • The physical size will be an issue for certain uses, mainly the nose and overall diameter of the motor housing.

  • Portable, enough power, light weight for hobbies and small fix it jobs.
  • Nice product, moderate weight in your hand.

What customers say about "Features"
Dremel 4300-5/40 High Performance Rotary Tool Kit
  • My favorite feature on this on is that you get separate switches for on/off and speed.
  • This unit is unexpectedly much larger than the original and be rather cumbersome to handle. It has lots of power.
  • Nice quality Dremel with much more power and torque than my older models. Use it with the 220-01 Workstation (press) to drill PC boards.
  • The more powerful motor is why this one is the one to buy if you use the tool a lot. It will not burn up the way cheaper units / off brands often do.
  • Extremely versatile and very easy to change accessories. Now I have two excellent Dremels, just need to add the Fortiflex Flex Shaft Tool and my collection will be complete!
  • Cooling fan is in the front and gets really hot making it hard to do any detail work for any time.
Dremel 8220-1/28 Cordless Rotary Tool
  • Takes all of the dremel attachments unlike some of the smaller models.
  • Handy case that stores the 8220 and many more accessories.
  • Quick release collar is new and great feature, no more wrench to chase down.
  • One of the best feature is that it fits all my Dremel accessories.
  • The only bad point is the carrying case: I wish the case were a bit more flexible in allowing more accessories to be stored with it.

What customers say about "Power"
Dremel 4300-5/40 High Performance Rotary Tool Kit
  • The power is great but the variable speed adjustment is rough.
Dremel 8220-1/28 Cordless Rotary Tool
  • Plenty of torque and speed for grinding large dog nails. Don't waste your money on the cheaper lover voltage ones that bog down under the slightest load.
  • 12 volt separate battery and charger incase you want to have additional batteries. It is a quick charging battery taking about 1 hour.
  • Best feature is the removable battery. I can always have one on charge while I'm using it.
  • The battery holds a charge for a long time, and is fast charging.
  • I wonder if I got a dud for a battery. I can only do about 20 minutes on a medium speed before the battery dies. I am not impressed.
