Features:

• The JACOBS plain Bearing Chucks are the world’s most widely used.
• Medium duty for use on all types of floor, bench or portable machinery.
• Jaws are specially treated and centerground to ensure extended life and high gripping power.
• All working components are hardened and ground.
• 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.
• Plain bearings are designed with a 1-piece gearing and sleeve for reducing teeth breakage. They are used for medium duty operations with stationary drilling, turning, milling and woodworking machines.
