• Best For: Installers who need a 3-inch finished hole in ceramic tile or marble, such as for a pipe or fixture penetration.
• Highlight: A continuous diamond rim, which MK uses on its tile bits larger than 2-1/4 inches, plus a replaceable pilot drill and wet or dry use.
• Expert Note: Choose by finished hole diameter: this 3-inch bit has a continuous rim, unlike the turbo-style rim on MK-290 sizes up to 2-1/4 inches.
