I can't speak for that exact kit, but they are usually 1/8 inch (.125) or 3mm (.118).

Seven thousand of an inch doesn't usually matter much unless your device uses short collets.

I just measured the kit I purchased recently and found the shanks to be .123". They work fine in my Foredom 44T handpiece collets.



Thank you

I have a 1/8" device and I need to be sure because there are 2 mm shanks out there
