Extra-Grip Taper-Mount Keyed Drill Chucks

Jacobs Taper Mount

A ball-bearing design provides increased gripping force to keep bits from slipping, which allows these chucks to take on high-torque drilling applications. Also known as super chucks, they are excellent for use on high-speed drilling machines, milling machines, jig borers, and lathes. All require an arbor (sold separately).
