Jacobs Super Chuck Keyed Ball Bearing Drill Chucks
Features:
- Specially engineered for heavy duty close tolerance production drilling.
- Ideal for use on jig borers, milling machines, lathes and radial drill presses.
- Ball bearing construction maximizes gripping force and drilling accuracy.
- Jaws are centerground for absolute straightness and alignment.
- All working components are hardened for maximum wear resistance
- Tapered mount drill chucks have an internal Jacobs Taper (JT) that is press-fit onto a corresponding JT arbor (shank) or spindle.
- Keyed chucks are engineered to either loosen or tighten the hold on a tool by using a key. Keyed chucks offer the advantage of applying additional torque on the bit when slippage is a concern during heavy-duty applications.
- Ball bearings are designed to reduce friction in the tightening mechanism and provide a better grip on the drill. They are used for heavy-duty machining and require a key for tightening or loosening.
