Walter Surface Technologies 01M619 Prentice Drill Bit 1-7/16in 6in Overall Length

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.
