Gundlach 1/4" (6 mm) Diamond Mill Bit

This vacuum brazed diamond Bit is used to create and shape half-moon side indentations and enlarge and/or shape existing holes in porcelain, ceramic, granite and marble tile. Very suitable for creating round side indentation necessary to accommodate pipes or electric lines.

The bit is fast cutting and provides a good finish. The diamond portion of the bit is 2" long and is designed to mount on a standard angle grinder 5/8"/11 standard thread without the use of an adapter.

Can be used wet or dry.

Please note. FPU bits aren’t designed to cut an initial hole but rather to shape and enlarge existing holes.
