Features and Benefits
Threaded mount drill chucks have an internal thread for securing to a power drill spindle or a threaded arbor.
Keyless chucks are engineered to quickly loosen and tighten a tool on the chuck collar of the drill, either by manual operation or when torque is applied. Rotating the chuck collar in a counterclockwise direction will loosen the tool.
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.
