Tuff Stuff 432 Glass Tile Bit

The Tuff Stuff 432 is a carbide-tipped drill bit designed for glass, ceramic and marble tile. It produces clean round holes without chipping or cracking the material. The accessory is intended for rotary drilling only and must not be used with percussion or hammer action. It suits installers and DIY users who need precise holes in brittle surfaces.

Capacity And Headroom

Tungsten carbide spear points handle standard tile thicknesses and typical glass panels encountered in bathroom or kitchen work. The bit cuts smoothly when run at slow speeds with light pressure and adequate lubrication. It runs out on very thick stone slabs or hardened porcelain that exceed the cutting length, and it cannot be used for impact-driven applications.

Rotation Only Constraint

This bit is strictly for rotation-only drilling; percussion or hammer modes will destroy the carbide tip and shatter the workpiece. Users must select a drill driver without impact function and maintain low RPM throughout the cut. Buyers who need a bit compatible with hammer drills or SDS-plus machines should choose a different accessory.

Questions about this item

Will the 1/2" shank of the PTAGTB432 fit my older 3/8" keyed drill chuck?

The 1/2" shank requires a chuck capacity of at least 1/2". A 3/8" chuck cannot accept it; you would need a drill with a larger chuck or a 1/2" to 3/8" reducing sleeve, which is not included.

How can I confirm the carbide tip is cutting correctly in glass or tile?

A clean, round hole with no chipping or cracking around the edges indicates proper cutting. Use rotation only at slow speed with steady pressure; any hammer action or high RPM will damage the tip and the material.

Does the PTAGTB432 come with a pilot bit, lubricant or a storage case?

The package contains the single carbide-tipped drill bit only. Cutting fluid, a pilot drill, a depth guide or a case must be purchased separately.
