1-3/16 inch Prentice drill bit
The Walter Surface Technologies 01M612 is a heavy-duty cobalt-blend bit built for 1/2 inch chucks on portable drills, drill presses and magnetic-base machines. It targets metalworkers who need a single large-diameter cutter for mild steel, non-ferrous alloys and stainless steel.
135 degree point and 1/2 inch shank
The 135 degree split point eliminates the need for a pilot hole in many materials, while three flats on the shank stop the bit from slipping inside the chuck. These geometry limits mean the bit works only where a 1/2 inch capacity chuck is available.
3-1/8 inch flute and 6 inch overall length
The 3-1/8 inch flute clears chips from holes up to that depth in one pass, and the 6 inch overall length gives reach through thick plate or stacked workpieces. Beyond that flute length chips can pack, so deeper holes require peck drilling or a longer bit.
