• Best For: Stone fabricators and installers drilling 3-inch holes in granite with a wet drilling setup.
• Highlight: A 3-inch cutting diameter, much larger than the 1-inch to 2-1/4-inch bits in the same MK-290GW series.
• Expert Note: This is a wet cutting granite bit, so run water while drilling; MK also lists a separate shank adapter, part 260000T, for MK-290GW bits.
