## Questions & Answers

**Q: I have a draper mini tool. the shaft is 6mm. can i attach the chuck without the connecting rod?**
A: IT IS A SMALL TAPER

**Q: Will this fit on a Dremmel or other rotary tool?**
A: With a little ingenuity with either a file and metal epoxy or a suitable tapping thread, yes you can fit one on a Dremel (I have just done so on my Dremel 3000). You either have to tap this chuck from the bottom to fit the thread of the Dremel spindle (I would estimate a 7mm diameter  thread). Or like me, you can turn on your Dremel and then file the thread off the spindle (like a lathe) to the narrowing dimensions of the brass adapter plug shown in the main pictures and then use something like JB Weld epoxy to firmly attach this chuck onto the newly filed down spindle.

**Q: Hi. Will this chuck fit a spindle with a diameter between 2.08mm and 2.10mm? Or will it be off centre**
A: I would say no

**Q: what voltage does the electric motor run at?**
A: It does not have a motor it is a Chuck head!!

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Small well made, ideal.
  

*by M***K on Reviewed in the United Kingdom on 24 March 2020*

I have a very elderly (close to 40 years old) Expo 12v mini drill and wanted something better than the collet assembly that it came with. This chuck is well made and seems perfectly centred once fitted to the drill. The taper was a very tight fit on the drill shaft and needed some gentle persuasion to to fully seat, but that's fine.When I received the package the grub screw for the taper was loose in the envelope and not in the bag with the rest of the chuck. Fortunately I heard it rattling, because otherwise it would have gone on the floor and probably never been seen again.Very pleased. I doubt I'll need another one, but if I did, I'd have no hesitation to buy again.I knew there'd be something, but eventually the taper/chuck stopped binding together. I wasn't sure what to do about it, but eventually decided to use a thread lock fluid to bind them. Not ideal, but it worked...

This is the third chuck I have bought, completely satisfied.

    "Dainty" chuck and adapter, great for modelling work.
  

*by M***E on Reviewed in the United Kingdom on 22 March 2022*

Nice miniature chuck Unfortunately one of the adapter's grubscrew threads not properly cut and won't accept the grubscrew.  I'll tap it out when I have the time to do so.
