Tapered mount drill chucks have an internal Jacobs Taper (JT) that is press-fit onto a corresponding JT arbor (shank) or spindle.

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.

Stainless steel is a strong, corrosion-resistant alloy with excellent resistance to heat. It is used in high-stress, outdoor and corrosive applications.
