Other questions and our answers

Will this fit in a drill with a two piece collet that is 1/8"?

Jennifer Steger

These carbide ball burrs have a 3/32" (2.35mm) shank.  1/8" is equal to 3.175mm so if the collet tightens down then yes you will be able to hold these.  Otherwise you will need an adjustable chuck (one that tightens and loosens to hold various shank sizes) Depending on the sort of drill you have, most have a chuck available to purchase that will attach to the drill.  Dremel for instance have a Dremel Multi Chuck that does the job. 

HI just a quick question would carbide ball burrs be suitable for engraving stainless steel and is there a lubricant that could help with engraving process ? regards Simon

Hi Simon, 

Yes our carbide burrs work well on stainless steel, you can use a regular cutting fluid or water will work too.

Any further questions just let us know.
