About This Product
10-Piece Diamond Drill Bit Set for Porcelain and Stone
The BIHUI® Diamond Turbo Drill Bit Set combines core drilling, hole enlargement, edge refinement, and cutting tools for porcelain, marble, and granite. Designed for compatible angle grinders, the vacuum-brazed diamond tools provide a versatile setup for creating and adjusting plumbing penetrations, fixture openings, and other holes in hard tile and stone.
Six Diamond Core Bits for Common Hole Sizes
Six diamond core drill bits provide 1", 1-3/8", 1-5/8", 1-3/4", 2-3/8", and 2-5/8" drilling diameters. Their turbo diamond construction supports fast drilling and extended service life in demanding materials, while the 5/8"-11 threaded connection mounts to compatible angle grinders.
Finger and Cone Mills for Hole Adjustment
A 20 mm diamond finger bit and 20–48 mm diamond cone bit allow installers to enlarge existing openings, smooth edges, and make controlled adjustments when a drilled hole requires additional clearance. These milling tools help refine the opening after the initial core has been removed.
5" Diamond Cutting Disc and Cooling Wax
The set also includes a 125 mm (5") diamond cutting disc for complementary tile and stone cutting tasks. Cooling wax helps manage heat and support drilling performance, while the included carrying case keeps the complete set organized for storage and jobsite transportation.
