GEKO G00521 drill chuck head with 13 mm capacity and 1/2" connection is a metal-constructed chuck designed to secure twist drills and accessories in hand-held and benchtop drills. It supports bits up to 13 mm in diameter and fits tools with a 1/2" drive interface. The metal construction provides rigidity for general drilling tasks in wood, plastic and light metals where a robust, simple chuck is required.

Advantages

The metal construction offers enhanced durability and stable clamping compared with plastic components, while the 13 mm capacity accommodates common drill bit sizes for DIY and workshop use. The 1/2" connection ensures compatibility with a wide range of drills and adaptors. The chuck provides straightforward tightening and reliable retention of round- and straight-shank twist drills, reducing slippage during standard drilling operations.

How to use

Mount the chuck onto a drill spindle or adaptor with a 1/2" interface, ensuring it is securely seated and tightened according to the drill manufacturer’s instructions. Open the jaws, insert the drill bit up to the recommended depth, then close the jaws and tighten firmly to ensure the bit is centered and held without play. Confirm secure clamping at low speed before proceeding to full operating speed. For removal or replacement, loosen the chuck jaws and withdraw the bit, or detach the chuck from the spindle following appropriate tool procedures.

Usage recommendations

Use appropriate drill speeds and feed pressure for the material being worked: lower speeds for metals, higher speeds for wood and plastics. Regularly inspect the chuck jaws for wear or debris and clean before installation of bits to maintain accurate centering and secure clamping. Use proper personal protective equipment when drilling.
