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 specification is designed for industrial-level cutting systems.

• .404 Pitch refers to the distance between drive link rivets. It is a large pitch system used for high-power chainsaws.

• .063 Gauge (1.6mm) refers to the thickness of the drive link that fits into the guide bar groove.

This combination creates a chain that is:

• Extremely strong and durable

• Suitable for high horsepower chainsaws

• Designed for heavy-duty cutting applications

• Ideal for professional forestry operations

Technical Specifications

Applications

The .404 .063 chainsaw chain is widely used in:

• Professional forestry harvesting

• Large tree felling and bucking

• Industrial logging operations

• Timber processing plants

• Commercial wood cutting contractors

• High-power chainsaw equipment (90cc+ class saws)

Why Choose .404 .063 Chainsaw Chain?

The .404 system is designed for professional logging environments where performance and durability are critical.

1. Maximum Cutting Power

Designed for large saws that require aggressive cutting performance on hardwood and large diameter logs.

2. Heavy-Duty Construction

Built with reinforced steel materials for extreme working conditions.

3. High Durability

Heat-treated components improve wear resistance and extend service life in continuous operations.

4. Stable Cutting Performance

Reduces vibration and maintains cutting stability during long working hours.

5. Professional Forestry Standard

Widely used in global logging and industrial forestry operations.

Compatibility

This .404" .063 chainsaw chain is compatible with many professional large chainsaws, including:

• STIHL MS 661 / MS 880 class saws

• Husqvarna large professional chainsaws

• Echo high-power forestry saws

• Other 90cc+ professional logging chainsaws

• Harvester and heavy-duty cutting systems (depending on setup)

Understanding .404 Pitch vs Other Chains

The .404 chain is significantly larger than standard chains:

• .325 chain → light to medium cutting

• 3/8 chain → general professional use

• .404 chain → heavy-duty logging and industrial cutting

Because of its size, the .404 system requires high horsepower professional saws and is not suitable for small or mid-sized chainsaws.

How to Choose the Correct Chainsaw Chain

To ensure proper fit and performance, always match:

• Pitch (.404, 3/8, .325)

• Gauge (.050, .058, .063, .080)

• Drive links (DL count)

Incorrect selection may cause poor performance, chain damage, or safety risks.

What is a .404 .063 chainsaw chain used for?

It is used for heavy-duty forestry cutting, logging, and large tree processing with professional high-power chainsaws.

Is .404 chain bigger than 3/8 chain?

Yes. .404 chain is larger, stronger, and designed for industrial cutting applications.

Can I use this chain on a small chainsaw?

No. It is only suitable for high-power professional saws (typically 90cc and above).

What does .063 gauge mean?

.063 refers to the thickness of the drive link, which must match the guide bar groove exactly.
