Jacob's Super Chuck Ball Bearing Drill Chuck is specifically engineered for heavy-duty, close tolerance production drilling. It is adaptable to a wide range of production drilling equipment, jig borers, milling machines, lathes, and radials. Utilizing a ball thrust bearing to reduce friction in the chuck closing mechanism, it permits the application of more gripping force on drill shanks to maximize drilling torque under the most demanding machining conditions.
- Ball bearing construction maximizes gripping force and drilling accuracy
- Jaws center ground for straightness and alignment
- 1-piece sleeve eliminates crack between driving teeth often found in other designs
- Through-hardened sleeve teeth plus hardened nose and keyholes provide outstanding wear resistance
- Fluted sleeve standard
- Each chuck 100% inspected for performance and precision
- I.R. 0.003 in. maximum at half capacity
- Chuck key included

Jacobs 32BA1220 0-3/8" Cap. Plain Bearing Drill Chuck (1/2"-20 thread mount w/key)Made in U.S.A.Below Cost!
- 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.
- 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.
