11/16 inch drill bit with 1/2 inch shank

The Disco 12998 is a drill bit designed for pneumatic and power tool use. Its 11/16 inch cutting diameter suits medium-to-large hole drilling tasks in workshop or automotive settings.

Simple chuck installation with secure shank fit

The 1/2 inch shank inserts directly into compatible chucks for quick changes. Ensure the chuck is fully tightened to prevent slippage during high-torque pneumatic operation.

Suited for mechanics needing a single large bit

This bit serves technicians who need an 11/16 inch hole size without buying a full set. It is not for users requiring multiple diameters or smaller shank sizes for light-duty drills.

Questions about this item

What comes with the DISCO 12998 drill bit and what additional items are needed for use?

The package contains the 11/16 inch diameter drill bit with a 1/2 inch shank; a compatible pneumatic drill or driver with a 1/2 inch chuck must be supplied separately.

Which DISCO drill bit version should I choose for an 11/16 inch hole requirement?

Select the 12998 model when you need an 11/16 inch cutting diameter with a 1/2 inch shank; other DISCO models cover different diameters or shank sizes.
