Chain sharpening wheel GEKO G81201B 145 x 3.2 x 22.2 mm (100) for chainsaw chain sharpening

The GEKO chain sharpening wheel G81201B 145 x 3.2 x 22.2 mm (100) is an abrasive wheel designed for restoring and maintaining chainsaw chain cutters. It is intended for use with bench grinders and dedicated chain sharpening machines that accept a 22.2 mm bore. The wheel’s 145 mm diameter and 3.2 mm thickness deliver controlled material removal to reestablish sharp, consistent edges on cutter teeth, supporting safer and more efficient cutting in forestry and woodworking tasks.

Advantages

This abrasive wheel provides even cutting action and predictable stock removal to help achieve consistent bevel geometry across chain cutters. Manufactured for compatibility with standard 22.2 mm bore sharpening equipment, the wheel simplifies setup and replacement. Its dimensions make it suitable for most common chainsaw chain profiles, offering repeatable results when dressing or replacing worn cutter edges.

Suitable for

• Sharpening chainsaw chains on bench grinders and dedicated sharpening machines with 22.2 mm bore
• Regular maintenance of cutter edges for forestry and arborist equipment
• Workshops and professional settings performing frequent chain servicing
• Restoration of slightly rounded or dulled cutting teeth prior to field use

Key specifications

• Outer diameter: 145 mm
• Thickness: 3.2 mm
• Bore diameter: 22.2 mm
• Abrasion grade: suitable for chainsaw chain steel (designation 100)

How to use

Mount the sharpening wheel on a compatible grinder or sharpening machine with a 22.2 mm spindle, ensuring the wheel is securely fastened and balanced before operation. Align the chainsaw chain to the machine’s guide and set the correct grinding angle for the chain profile. Apply light, steady pressure and feed the chain past the rotating wheel to remove material until the cutter edge is restored. After sharpening, inspect each cutter for uniform bevel and perform a light deburring pass if necessary. Follow the machine manufacturer’s safety and mounting instructions throughout the process.

Usage recommendations

Use appropriate personal protective equipment such as eye protection and gloves, and check the wheel for cracks or damage before each use. Replace the wheel when wear or glazing reduces cutting effectiveness. Store in a dry environment away from extreme temperatures to preserve abrasive performance.
