Questions about this item

What size drill chuck is required for the 1/2in shank on this bit?

The bit has a 1/2in shank, so you need a chuck that opens to at least 1/2in. Most 1/2in-capacity drill/drivers and drill presses will accept it directly.

Will the 3-flat shank on this bit work with a standard 3-jaw chuck on an older drill press?

Yes. The three flats are designed to prevent slipping in a standard 3-jaw chuck, so it grips securely on older machines.
