Heavy-duty 17/32" drill bit

Walter SST+ Prentice drill bits are cobalt-blend tools built for portable drills, drill presses and magnetic-base drills with a ½" chuck. The 135-degree point geometry removes the need for pre-drilling, while three flats on the shank stop slippage. Extra-hard tips extend the interval between re-sharpenings.

Suited for metalworkers needing large holes

This bit handles mild steel, non-ferrous metal and stainless steel in a single pass. It is not for woodworkers, masonry crews or anyone drilling diameters smaller than 17/32". Buyers who need a full set of incremental sizes or a bit that fits a ⅜" chuck should look elsewhere.

17/32" diameter with 3-1/8" flute

The 17/32" cutting diameter and 3-1/8" flute length decide whether the bit reaches the required depth in your workpiece. Match these two figures to your hole spec before ordering.

Questions about this item

Does my drill need a 1/2" chuck to hold the 17/32" bit?

Yes, the shank requires a chuck with at least 1/2" capacity.

Will the 135-degree point start cleanly in mild steel without a pilot hole?

The exclusive point geometry eliminates pre-drilling in mild steel, non-ferrous metal and stainless steel.

How do I know the three flats are seated properly after tightening?

The flats prevent slippage inside the chuck; if the bit runs true without wobble, it is seated correctly.
