File Size Guide

File Size	Chain Type
4.0 mm (5/32")	Maya 3/8 Low Profile Endurance carbide chain
4.0 mm (5/32")	Maya 3/8 Low Profile Pro-Tipped carbide chain
4.0 mm (5/32")	STIHL RAPID™ Duro carbide chain in .325" and 3/8" pitch

Important: File size cannot be determined by chain pitch alone. Endurance and Pro-Tipped chains of the same pitch may use different file diameters. Check your chain type before selecting a file.

Why Use Diamond Files?

Designed specifically for sharpening tungsten carbide cutting edges
Provides controlled material removal for regular touch-ups
Helps maintain a smooth and consistent cutting edge

How to Use

Thoroughly clean and degrease the chain before sharpening.
Allow the chain to dry and secure it firmly.
Follow the existing cutter angle and profile.
Use light, even pressure and the same number of strokes on each cutter.

Diamond sharpening tools must be used on tungsten carbide cutters. Conventional chainsaw files and standard grinding wheels are not suitable for sharpening the carbide cutting edge.

Depth gauges or rakers are steel and should be maintained separately using a suitable flat file and depth-gauge guide.
