SAW CHAIN IDENTIFICATION Pitch, gauge, and drive link count are the key dimensions for matching a saw chain to a chainsaw bar and sprocket. Pitch is the average distance between two rivets. Common saw chain pitches include 1/4", .325", 3/8", and .404". Gauge is the thickness of the drive link that fits into the guide bar groove. Common gauges include .043", .050", .058", and .063". Length is normally identified by the number of drive links, so counting the old chain is the most reliable way to confirm replacement length.
	Semi-Chisel Cutter Semi-chisel cutters use a rounded working corner for smoother cutting and better tolerance in dirty or dusty wood. This cutter profile is easier to maintain, more forgiving with filing angle, and suitable for homeowners, farms, orchards, and general-purpose cutting.
	Full Chisel Cutter Full chisel cutters have a sharp square-corner profile designed for fast, efficient cutting in clean softwood. This style provides quick and precise cuts, making it a strong choice for users who need higher cutting speed and can maintain the chain regularly.

What is a .404" Pitch .063 Gauge Chainsaw Chain?

The .404 chain is one of the largest and strongest chainsaw chain standards used in the industry.

This combination creates a chain that is:

• Extremely strong and durable

• Suitable for large diameter hardwood cutting

• Designed for continuous heavy-load operation

• Ideal for professional forestry and logging machines
