Overview

• 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.
• 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.
