Ingco 13mm Keyed Drill Chuck | 1/2-Inch 20UNF Thread Replacement Clamping Head with Chuck Key (KC1301)

The Ingco KC1301 Keyed Drill Chuck is a durable replacement component and power tool accessory engineered to provide a tight, slip-free grip on rotating drill bits, hole saws, and driver adapters. Featuring a versatile clamping capacity that spans from 1.5mm up to a maximum of 13mm, this chuck accommodates a wide array of straight and cylindrical round shanks, making it an essential upgrade or replacement for standard bench drills, corded impact drills, and rotary hammer configurations.

Constructed entirely from high-grade alloy steel, the chuck is designed to withstand continuous concussive impacts and high rotational friction without expanding or losing grip consistency. It utilizes a standard 1/2"-20 UNF threaded inner connection profile, ensuring direct compatibility with the spindle shafts of most major power tool brands. The assembly includes a matching, precision-fit steel chuck key, allowing operators to apply maximum manual leverage to lock accessories down firmly, eliminating bit spinning under heavy load conditions.
