Dremel has come out with their most powerful rotary tool to date, the 4200. Also described as the most versatile and advanced addition to the Dremel lineup, the 4200 features a new EZ-change tool-free collet lock, improved ventilation, and a new collet design.
The 4200 delivers variable speed 5,000-35,000 RPMs, and electronic feedback maintains the set speed even under heavy loads. It will launch with one kit configuration, 4200-6/40, that includes 6 attachments and 40 accessories.
EZ Change Tool-Free Collet Lock
Dremel designed the 4200 with a new EZ Change tool-free collet lock that allows for quick and easy bit and accessory changes. This also means that the 4200 requires new collets that are not compatible with other current or past rotary tools.
As pointed out by Kyle in the comments, it appears that the collet can be locked and unlocked with the slide of a switch at the front of the tool. Dremel recently released a new EZ Twist collet tool in their 3000 and now 4000 series rotary tools, but the EZ Change design looks far quicker and easier to use.
Our feeling is that the new collet design also allows for better bit, bur, and accessory gripping and heavier-duty usage, but we haven’t yet heard official word from Dremel about all of the benefits of the new design.
The 4200-6/40 kit also comes with a drive coupling adapter that makes the 4200’s new collet design compatible with Dremel’s 225 flex-shaft, 575 right angle tool, and 670 minisaw attachments.
We’re excited about the new Dremel and will try our best to get our hands on one to test out. For what it’s worth, Dremel representatives seem quite excited about the new model as well, and not just in the way product managers typically are. This is the most advanced and most powerful rotary tool they’ve designed to date, and everyone we’ve spoken to seems quite proud of the 4200 and its performance.
MSRP for the 4200-6/40 kit is $129, and it is available via Amazon and home improvement centers.
