01CHAINSAWS
Precision for every chain pitch
The workbench holds a small, precise instrument rather than a bulky machine. This set of grinding heads sits quietly in the kit, ready to restore the cutting edge of a saw that has seen heavy use.
Designed for electric drills and grinders, these bits sharpen chains without removing them from the bar. They suit users maintaining various chain pitches, offering a practical solution for keeping blades keen.


02MATERIALS
Corundum core with titanium finish
Each bit features a corundum grinding head, a material chosen for its abrasive consistency. The surface is treated with a titanium plating process, which helps extend the service life of the tool. This construction ensures the abrasive face remains effective through repeated contact with hardened steel teeth.

04SIZING
Three distinct pitches covered
The set includes ten bits for each of three sizes: 4.0mm, 4.8mm, and 5.5mm. These correspond to specific chain gauges, such as 3/8 inch and .325 inch variations. Whether working with smaller or larger chains, there is a matching bit to align with the tooth geometry.
IN USE
Sharpening without disassembly
The design allows polishing directly on the chain while it remains attached to the bar. This saves time by eliminating the need to remove the chain from the saw body. The process is straightforward, requiring only steady pressure against the cutting teeth to restore their profile.
