Drill Chuck 16 mm GEKO G00542 — keyed chuck for drill/driver

Drill Chuck 16 mm GEKO G00542 — keyed chuck for drill/driver is a keyed drill chuck with a 16 mm maximum capacity, designed to accept round and hex shank bits. It provides mechanical, key-actuated tightening for secure bit clamping and reliable torque transfer. The chuck is intended for use with bench drills, handheld drills and drill drivers that require a keyed tightening mechanism and a 16 mm jaw capacity.

Advantages

The keyed jaw mechanism ensures consistent clamping force across a range of bit sizes, reducing slippage during drilling. Its 16 mm capacity accommodates common drill bits and many accessory shanks, while the keyed design allows precise tightening for tougher materials. Constructed for workshop and general-purpose use, the chuck offers straightforward compatibility with machines that accept a keyed chuck mount and prioritizes repeatable bit alignment and grip.

Suitable for

• General drilling in wood, soft metals and plastics
• Bench drill applications requiring a keyed chuck
• Handheld drills and drill drivers where a keyed tightening method is preferred
• Light workshop tasks and maintenance jobs

Key specifications

• Maximum capacity: 16 mm jaw opening for round and hex shanks
• Chucking type: keyed jaw tightening with pinion-and-gear key
• Compatibility: for use with bench and handheld drills that accept keyed chucks
• Function: mechanical clamping for reliable torque transfer and reduced bit slippage

How to use

Open the jaws by turning the chuck sleeve counterclockwise, insert the drill or accessory bit so it seats centrally, then use the matching chuck key in the geared socket to tighten the jaws firmly. Verify the bit is centered and secure by rotating the spindle by hand before powering the tool. For removal, insert the key, loosen the jaws by turning clockwise on the sleeve, and withdraw the bit.

Usage recommendations

Check compatibility with your drill’s spindle and mounting system before installation. Use the correct size chuck key and avoid overtightening to prevent damage to bit shanks. Inspect jaws periodically for wear and clean debris to maintain reliable clamping; replace the chuck if significant wear or damage is observed.
