Product Identity

The Tuff Stuff PTAGTB412 is a 3/16 inch glass and tile drill bit with a tungsten carbide spear point. It is designed for tradespeople and DIY users who need clean holes in brittle surfaces.

Build Integration

The bit fits a standard drill chuck and requires a rotary-only tool setting; percussion or hammer modes must be disabled. Slow drilling speeds and steady pressure free the user from cracked tiles and chipped edges.

Target User

This bit suits installers working with glass, ceramic or marble tile who value precision over speed. Buyers needing larger diameters, percussion capability or multi-material sets should look at other options.

Questions about this item

How deep can the 412 drill bit go before the carbide tip overheats?

The bit length is 2-1/4 inches and slow speeds prevent overheating during sustained drilling.

Does the tungsten carbide spear point generate excess heat or noise when run all day?

Slow drilling speeds keep heat low and the rotation-only design avoids percussion vibration.

Must I already own a variable-speed drill to use this PTAGTB412 bit correctly?

Yes, a drill that runs at low RPM is required because the bit is for rotation only, not percussion.
