Disco 12996 drill bit — 21/32 inch diameter

The Disco 12996 is a pneumatic drill bit built for heavy-duty metalworking where a 21/32 inch hole is required. It fits tools that accept a 1/2 inch shank, making it suitable for industrial maintenance, fabrication and automotive repair shops. The bit is supplied new and ready for immediate use on compatible equipment.

Straight 1/2 inch shank for direct chuck fit

The straight 1/2 inch shank seats securely in standard pneumatic drill chucks without adapters, reducing run-out and speeding up bit changes on the job. Its one-piece construction resists bending under high torque loads typical of large-diameter drilling in steel and cast iron. The simple geometry also allows easy resharpening to extend service life.

Replaces worn or undersized large-diameter bits

This bit replaces dull or damaged 21/32 inch cutters that no longer hold tolerance or produce clean holes. It is not for drills limited to smaller shank capacities or for applications needing a reduced-shank or hex-shank interface. The jump is worth it when hole accuracy and tool rigidity matter more than shank versatility.

Questions about this item

What shank standard does the 21/32" bit use, and what chuck size does that require?

The bit has a 1/2" shank, so it fits any drill or driver with a 1/2" chuck capacity.

What is the overall diameter of the cutting portion, and will it clear a standard 1/2" chuck body?

The cutting diameter is 21/32", which is larger than the 1/2" shank, so the chuck jaws close on the shank only.

How is the bit secured in the chuck, and what step do users often skip?

Insert the 1/2" shank fully into the chuck and tighten all three jaws evenly; the step often missed is fully seating the shank before tightening.
