Fitment and Compatibility

This disc is intended for chainsaw sharpening machines designed to accept a 100 mm diameter grinding wheel with a 22.0 mm bore and 3.5 mm thickness.

• Disc diameter: Your grinder must accommodate a 100 mm disc.
• Arbor: Requires a compatible 22.0 mm mounting arbor.
• Thickness: Check that your grinder accepts a 3.5 mm disc.
• Chain compatibility: Suitable for tungsten-carbide chainsaw chains, subject to grinder and cutter-profile compatibility.

Important: Some chainsaw grinders require a 105 mm diameter disc with a 22.2 mm (7/8") bore. This 100 mm disc has a 22.0 mm bore and is not a direct replacement for those wheels.

Check your existing grinding wheel's dimensions and your grinder manufacturer's specifications before ordering. Do not modify the disc or its mounting bore to fit an incompatible machine.
