I bought a couple of these but they don't fit my tool. Can someone let me know an actual tool (or two) that these are compatible with?

Hi They fit in anything with a 1/4 inch collet such as a die grinder or a foredom type flexible drive, they will not fit dremel and the like which are 1/8 inch drive Hope this helps Regards John

It says "a variety of materials" but doesn't actually specify. Would these be suitable for stone/cement etc.? Thanks to anyone who can help!

Hello, The Rotary Burrs will work on soft stone, but we would suggest staying away from concrete as you could risk breaking the teeth. Thank you,

Hello. is the 1/4 inch burr compatible with a 6mm chuck? slight difference. any model numbers of compatible rotary tools? thanks

1/4 inch is 0.35mm bigger than 6mm so will fit with no problem.

Hi does it fit dremmel?

The 1/8th shaft fits dremmel and any rotary tool. 1/4 (6 mm) requires a drill or rotary tool with larger chuck. For the larger 6mm shaft bits I tend to use a flexie shaft in a drill/grinder with 6.5mm capacity chuck.
