1/4" Glass & Tile Bit
The Tuff Stuff PTAGTB416 is a carbide-tipped drill bit designed for clean holes in glass, ceramic and marble tile. Tungsten carbide spear points cut round openings without chipping or breaking the material. It is sold as a single unit for rotation-only drilling.
Rotation-only drilling
Suited for installers and DIY users who need precise holes in brittle surfaces using a standard rotary drill. Not for percussion or hammer-drill modes, and not for drilling metal, masonry or wood. Buyers who need impact-rated bits or larger diameters should look at other options.
2-1/4" overall length
The bit handles standard tile and glass thicknesses with the recommended slow drilling speeds. Its 1/4" cutting diameter limits each hole to that size, and the carbide tip will wear faster on abrasive stone. For deeper or wider holes a different bit is required.

Questions about this item
What drill chuck size do I need to hold the 1/4" shank on the PTAGTB416?
A standard drill with a chuck that opens to at least 1/4 inch will grip the shank securely.
Can I use this carbide-tipped bit in the same cordless drill I use for wood and metal twist bits?
Yes, it fits any rotary drill, but you must disable hammer action and run at low speed to avoid cracking the tile.
How will I know the PTAGTB416 is cutting correctly once I start drilling?
The tungsten carbide spear point should produce a clean, round hole in glass or ceramic without chipping the edges when used at slow rotation speeds.
