Jacobs - 0.625, 2 to 12.7mm Capacity, Threaded Mount Drill Chuck - Keyed, 45.52mm Sleeve Diam, 72.39mm Open Length

Item #: 08590143
Brand: Jacobs
Model #: 6291
Exact Tooling IR#: 04

Features and Benefits

Threaded mount drill chucks have an internal thread for securing to a power drill spindle or a threaded arbor.

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.

Steel is strong and durable but less corrosion resistant than stainless steel. To improve its resistance to corrosion, it may receive additional finishes and coatings.

Jacobs - 0.7 to 6.5mm Capacity, Integral Shank Drill Chuck - Keyed, Straight Hex Shank, 28.7mm Sleeve Diam

Item #: 96033527
Brand: Jacobs
Model #: 30248D
Exact Tooling IR#: 04

Features and Benefits

Integral shank drill chucks are designed with the arbor (shank) built into the drill chuck, providing greater rigidity and concentricity than a press-fit tapered mount.

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.
