17/32" Drill Bit for Heavy-Duty Drilling

The Disco 12988 drill bit has a 17/32 inch diameter and a 1/2 inch shank for secure chuck grip. It is designed for creating precise holes in metal, wood or plastic using a standard power drill. Professional tradespeople and serious DIY users will find it suitable for demanding workshop tasks.

1/2" Shank Limits Chuck Compatibility

The 1/2 inch shank requires a drill chuck that accepts this size or larger. Smaller 3/8 inch chucks cannot hold this bit securely. Users must verify their drill capacity before purchase to avoid slippage or damage during operation. The straight shank design suits keyed and keyless chucks alike.

Replaces Worn or Undersized Bits

This bit replaces dull, broken or smaller-diameter bits when a 17/32 inch hole is required. The step up is worth it when the application demands this exact size for bolt clearance, pipe tapping or hardware installation. It is not for buyers needing metric sizes, reduced-shank variants or comprehensive bit sets.
