GS Ball Bearing Chucks are specially designed for HEAVY
DUTY drilling applications on production drilling machines,
jig borers, milling machines, lathes and radials. The ideal
choice for those jobs that require close tolerance drilling.
The ball thrust bearing reduces friction in the chuck's
closing mechanism, so the operator can apply more
gripping power on the twist drill shank.

• High precision, premium tolerance
• The jaws feature a TIN coated surface treatment to assure durability.
