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. See photos for details.
