Small grinding bits


I have a set of small grinding bits with 1/4" shafts, the type that might be used with a hand grinder or Dremel.

Would these be suitable for grinding form tools for the lathe in 3/8" HSS blanks?  I would likely mount the bits in the mill.

Hi Kvom,

The only thing I can think you would have problems with would be the speed. Even at the highest you can get on your mill, I don't think it will be fast enough for the mounted points to do their job, and might just wear away very quickly rather than grind the material.

As you know, the grinding medium is bonded together with resins, and by running too slow, the resin being soft, is liable to let go of the grit without it doing any grinding. The only thing you can do is try it.


Hi Kvom.
Dont know about tool bits but I found the cylindrical one excellent for grinding
flats in brass held in the qctp.
