The MK Diamond MK-290GW is a 1-3/8 inch premium-grade wet cutting diamond bit for granite. It carries a 5/8 inch-11 thread and is used by stone fabricators and countertop installers making holes in granite where a wet feed keeps the bit cool and the cut clean.

Notes on fitment
MK Diamond publishes additional dimension figures for this bit only as a labeled drawing, without a text key, so segment height and usable drilling depth are not restated here. MK Diamond also does not publish a segment count, segment bond or a maximum RPM for the MK-290GW line. This is a different product from the MK-290 tile bit, which uses a 10 mm shank and a replaceable pilot drill. Confirm the thread and water feed on your tool before ordering.
