Super hard stone has no chance with this new 1/4″ wet cutting core drill bit. Used wet with either a squirt bottle or submerged in a tub. This 1/4″ premium diamond will core the hardest materials. We have tested this product on some of the hardest granites, rock and stones and it is the real deal.
Made in Germany
1/4″ diameter holes
4″ over-all length.
3/8″ shank size. Great for cordless 3/8″ chuck drills.
Can be used wet or dry but will work and last much longer when used wet.
As a foot note. Sent these to a granite contractor for testing. He said it saved him hours in labor and we had gained a customer for life.
