JT33, 0 to 1/2″ Capacity, Steel Tapered Mount Drill Chuck;Keyless | 84217280

84217280 84217280 0-1/2 X 33 JT ECON KEY 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. 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. Tapered mount drill chucks have an internal Jacobs Taper (JT) that is press-fit onto a corresponding JT arbor (shank) or spindle.
