Drill Chuck 13 mm GEKO G00503 B16 with Key

GEKO Drill Chuck 13 mm G00503 B16 with Key is a keyed metal chuck designed to hold straight-shank drill bits up to 13 mm in diameter. The B16 taper mounting makes it compatible with drills and drill presses that accept B16 chucks. The keyed tightening mechanism ensures a firm mechanical grip on the bit for consistent rotation and reduced slippage during general drilling operations and workshop tasks.

Advantages

The keyed design provides positive, repeatable tightening torque, reducing the risk of bit slip under load. Constructed from hardened steel components, the chuck offers wear resistance for extended use in DIY and professional environments. The 13 mm maximum capacity accommodates a wide range of common drill bit sizes used in wood, metal and plastic, while the B16 mounting allows straightforward installation on compatible spindles.

Suitable for

• General drilling in wood, metal and plastic with straight-shank bits up to 13 mm
• Use on hand-held drills and drill presses equipped with a B16 taper
• Workshop, garage and home DIY tasks requiring secure, keyed bit clamping

Key specifications

• Maximum bit capacity: 13 mm
• Mount type: B16 taper
• Operation: keyed tightening with supplied chuck key
• Material: hardened steel construction (body and jaws)
• Suitable bit shank: straight shank bits

How to use

Insert the drill chuck onto the machine spindle matching the B16 taper and seat it firmly according to the tool manufacturer’s guidance. Open the jaws by turning the chuck sleeve counterclockwise, insert the straight-shank drill bit to the required depth and center it in the jaws. Use the supplied key to tighten the chuck by turning the key clockwise in each socket position to ensure even jaw engagement. Before operation, confirm the bit is secure and aligned, then operate the drill at the appropriate speed and feed for the material.

Usage recommendations

Regularly inspect the jaws and key for wear and remove chips or debris from the jaws. Apply a light machine oil to the moving parts periodically to maintain smooth operation. Do not exceed the recommended bit diameter and avoid using tapered or reduced-shank bits that do not fit the straight-shank jaw profile. For safety, always disconnect power before changing bits and follow the drill or press manufacturer’s safety instructions.
