Finger Bits

Diamond finger bits for enlarging holes, shaping inside curves, and finishing cutouts in granite, marble, quartz, and other stone. Finger bits are used to clean up sink cutouts, enlarge existing holes, and smooth interior curves that standard core bits and blades cannot reach. They are indispensable in countertop fabrication for producing clean, finished openings.

Our finger bits come in various diameters and lengths, with options for both wet and dry use. They mount on angle grinders and die grinders for quick, controlled material removal.

Keep finger bits in your tool kit for clean sink cutouts and precise hole finishing on every countertop job.
