Walter Prentice Drill Bit 1-7/16in
This Walter Surface Technologies 01M619 Prentice drill bit is a heavy-duty large diameter bit built for portable drills, drill presses and magnetic base drills with a 1/2in chuck. The cobalt blend construction and extra hard tips extend the interval between re-sharpenings. A 135deg point geometry removes the need for pre-drilling in many materials. Three flats on the shank prevent slippage inside the chuck.
Suited for steel and non-ferrous metal drilling
The bit handles mild steel, non-ferrous metal and stainless steel, making it a fit for fabrication and maintenance tasks that require a 1-7/16in hole. Builders who need a smaller diameter, a reduced shank for a 3/8in chuck or a longer overall reach should look at other options. The 3-1/8in flute length also limits the maximum depth in a single pass.
1-7/16in diameter with 1/2in chuck requirement
The decisive specification is the 1-7/16in drill diameter combined with a shank that demands a 1/2in chuck capacity. If the drill or press cannot accept that chuck size, the bit will not fit. Confirm the chuck capacity before purchase.

Questions about this item
How much heat builds up when the 1-7/16in cobalt blend bit runs all day in a ½in chuck?
The cobalt blend and bronze SST treatment reduce friction so the bit stays cooler during extended drilling in mild steel, non-ferrous metal and stainless steel.
What chuck size must my drill already have to accept the ½in shank with three flats?
A ½in chuck capacity is required; the three flats on the shank prevent slippage inside that chuck.
Will the 135deg point geometry let me skip pre-drilling when I keep using my older portable drill?
Yes, the exclusive point geometry eliminates the need for a pilot hole even on older portable drills, drill presses or magnetic base drills.
