## Description

Three-jaw Steel Drill Chuck. For all prepared MICROMOT devices. Advantageous when working with different shafts. Capacity 1/64" - 1/8" (0.3 - 3.2mm). Note: Drill chucks provide more convenience to quickly change the tools when working with shafts of varying diameters (e.g. HSS drills as per DIN 338). However, because of their technical setup, they have a few drawbacks compared to collets: Less clamping force and higher concentricity tolerances. If high precision is necessary, then working with MICROMOT steel collets is a must.

Review: Works great (with slight mod) for Harbor Freight Item# 68696 Variable Speed Rotary Tool - I've had my Harbor Freight Chicago Electric 35,000 RPM Variable Speed Rotary Tool for over a decade and have been mostly happy with it. Always hated the poor quality stock chuck which forced me to use a wrench/tool to fully tighten and remove the bits. Over time, the jaws deformed and the bits would wobble dangerously at moderate to high tool speeds. It got to the point where I started avoiding the tool. Then I decided to try my luck with this tool free chuck from Proxxon. Now my HF Rotary Tool is better than ever and I have zero fears about using it at high speed. The bits stay perfectly centered and get a positive mount every single time using just fingers and the stock yellow lock tab. Very minimal, almost non existent wobble throughout the whole speed range with all my attachments and bits. Very happy with this mod/repair and will absolutely recommend it to anyone. Minimal mods required, I don't recall fully but I think all I had to do was chop down the original circular plastic trim piece with a hacksaw blade to clear the deeper mounting base on the new chuck. I suppose you could use the tool without the trim ring, but I prefer to keep it on. See my detailed pics.
Review: Proxxon 28941 MICROMOT Three Jaw Keyless Chuck for rotary tools. - I bought this micro keyless chuck to use with my rotary tool (dremel type) and replace a bunch of collets. This chuck WILL FIT DEVICES WITH SPINDLE OUTER DIAMETER 8 mm and METRIC THREAD 0.75 mm STEP ONLY. IT WILL NOT FIT ORIGINAL DREMEL DEVICES because they have spindle with DIFFERENT MECHANICAL DIMENTIONS. Before go to buy this chuck, measure outer diameter of yours device spindle to be sure in compatibility. This device is well made with high pricision and excelent fits my device, the China made FUNCTIONAL analog of the Dremel 4000 motor. There are NO any wobblings up to highest speed of 38K r.p.m. It is fantastic. One recommendation about how to use this chuck - simply replace the collet's locking nut with this chuck and DON'T remove collet from hole. That's it, nothing more, and it will serve you very well. I've placed my order on Friday and got it on next Monday at noon - excelent delivery speed. I'll recommend this high quality product for COMPATIBLE devices.

## Questions & Answers

**Q: Will it work with a Dremel 200**
A: NO, it will NOT fit the Dremel 200 device. This chuck is for spindle with 8 mm outer diameter and 0.75 mm step thred (METRIC thred) only. Dremel devices are using spindle with IMPERIAL threds which incompatible with METRIC ones.

**Q: Not happy.  this won't fit my 2850 micromot 50/e - not enough shaft length.  is there a workaround for this?  can i stuff washers into it?**
A: This chuck fits only 50/EF model.
Models 50, 50/E works ONLY with collets!

**Q: Will this fit Wen 2307?**
A: From previous customer: Not positive, but I'm willing to bet the answer is yes. I have the Wen 2305 and it fits. I got 2 of them. One for the rotary tool and one for the flex shaft attachment. The only bad part is I had to grind out the middle of the plastic part that screws over the collet nut because this piece is much wider and wouldn't seed all the way down without shaving it a little. I am glad I bought them. Haven't had one issue with either one. Well worth it. I Hope this Helps

**Q: Will this fit my model ib/e proxxon?**
A: Unfortunately the 28941 Keyless Chuck will not fit on the Proxxon Rotary Tool IBS/E. Another option would be to use a Proxxon 28622 Flexshaft. This flexshaft has the 28941 keyless chuck on it.

### ⭐⭐⭐⭐ Does Not Fit All Proxxon - Check Your Model First!
*by J***K on January 19, 2024*

Breaks my heart as I had wanted one of these for a long time. Couldn't remember to order! Finally did and was very disappointed that it does not fit my IB/E motor tool. And they apparently don't make one that does according to the Proxxon web presence. I'll eat it because if I had read the picture of the wrapper more closely, it actually excludes my model number. I only gave it 4 Stars because what playing with it I was able to do showed the teeth did not close evenly. It might be better in use on the proper tool, but it seems just like the cheap one that went on my old Dremel that flew apart years ago.
