Diamond grinding head (1/4")

The part was exactly what I needed!

This grinder bit is very good for what we do. Hand paint porcelaine clock.

Works good as a combinaison with diamond drill bit and Inland 1/4 diamond hollow bit

1/4" Grinding bit - very useful

I ordered the bit in order to grind/punch holes in 3mm glass and it works very well. I've also used it to grind 1/4 inch curves in my glass pieces.
