Drill Bit for Glass and Tile

The ARTU USA INC drill bit uses cobalt and tungsten carbide tips to bore clean holes in porcelain tiles up to scratch hardness 8. Its unique four-face point grinding prevents the bit from walking so tape or centre punching is not required. The ground double flute clears dust quickly and reduces clogging for longer bit life. A 5/32 inch pilot bit is included.

Upgrade from Standard Masonry Bits

Standard masonry bits often skid on glazed surfaces and chip brittle materials. This bit replaces them when you need precise holes in hard tile without applying heavy pressure. The jump is worth it for installers who want faster starts and cleaner finishes on porcelain rated to hardness 8.

Check Drill Speed Before Use

The motor must run between 400 and 600 rpm for correct operation. Verify your drill can maintain this low speed range under load. Ensure the chuck accepts a 5/32 inch shank and that the 3-1/8 inch overall length suits your workspace depth.
