Drill Chuck GEKO G00550 B22 key-operated 5–20 mm

Key-operated drill chuck GEKO G00550 B22 key-operated 5–20 mm is a replacement and upgrade accessory designed to hold straight-shank drill bits and rotary accessories with diameters from 5 to 20 mm. The chuck accepts a B22 taper mount and uses a mechanical key for tightening, providing a firm, non-slip grip suitable for a variety of drilling operations in metal, wood and common construction materials. It is intended for use with compatible handheld drills and drill presses that accept B22-type mounting.

Advantages

The metal body and precision-machined jaws deliver stable clamping and reduced runout under load, while the keyed tightening mechanism allows for higher torque transmission and secure bit retention compared with plain-keyless systems. The B22 taper interface enables straightforward replacement of worn chucks on machines with the same mount standard, and the 5–20 mm clamping range covers a wide span of common bit sizes used in workshop and jobsite settings.

Suitable for

• Replacing a worn or damaged drill chuck on B22-compatible handheld drills
• Upgrading drill presses and bench drills that accept B22 taper mounts
• Drilling metal, wood and masonry when using appropriate drill bits
• Applications requiring higher clamping force and torque transmission

Key specifications

• Clamping capacity: 5–20 mm
• Mount type: B22 taper
• Operation: key-operated (mechanical key tightening)
• Chuck style: three-jaw, straight-shank bit compatibility
• Material: metal body with precision jaws

How to use

Ensure the machine is powered off and disconnected from the power source before changing the chuck. Fit the B22 taper into the drill spindle or arbor and secure according to the host machine’s instructions. Insert the drill bit into the jaws, position it to the required depth, then use the supplied or compatible chuck key to tighten the jaws firmly. Verify correct seating and runout by rotating the spindle slowly by hand before powering the tool. Periodically check the chuck tightness during use and re-tighten with the key if necessary.

Usage recommendations

Use appropriate drill bits for the material being worked; apply cutting speeds and feed appropriate for metal, wood or masonry. Keep the chuck jaws clean and lightly lubricated to prevent corrosion and ensure smooth operation. Do not exceed the speed and torque limits specified by the host drill or press manufacturer. Replace the chuck if jaws show excessive wear or if runout compromises drilling accuracy.
