Overview

• Ball bearings are designed to reduce friction in the tightening mechanism and provide a better grip on the drill. They are used for heavy-duty machining and require a key for tightening or loosening.
• 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.
• 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.
