Jacobs 18N Ball Bearing Drill Chuck

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 accuracy
• Jaws center-ground for straightness and alignment
• One-piece sleeve eliminates crack between driving teeth
