Oregon M80 SpeedCut chainsaw chain for 20-inch bar — .325" pitch, .050" gauge, 80 drive links, narrow-kerf low-vibration

Built for arborists, landowners, and anyone who needs reliable cutting power without overworking the saw, the Oregon M80 SpeedCut chain pares down resistance with a narrow-kerf design and Micro Chisel cutters. It pairs with SpeedCut or other narrow-kerf bars and is compatible with popular saws such as certain Husqvarna models (H30 80 and 460 Rancher fit guidance). The chain’s reshaped cutter faces and LubriTec oiling channels help maintain smoother cutting and longer component life when used with the recommended guide bars.

How does the SpeedCut design affect cutting efficiency?

The SpeedCut narrow-kerf profile removes less wood per pass, so your saw uses less power to make each cut. That translates to faster cuts with lower fuel and engine load on the same saw and bar setup. The optimized cutter geometry also helps reduce vibration for steadier handling.

• Reduced kerf width for lower resistance
• Micro Chisel cutters for quicker bite and easier sharpening
• Reshaped cutting surfaces for improved cutting speed

Will this chain fit my 20-inch bar and saw?

This particular Oregon M80 chain is manufactured for a 20" guide bar with .325" pitch and .050" gauge and includes 80 drive links. It fits narrow-kerf bars, and is noted as compatible with Husqvarna H30 80 and models such as the 460 Rancher when using matching specifications. Always confirm your saw’s pitch, gauge, and drive link count before ordering.

• Pitch: .325"
• Gauge: .050" (1.3 mm)
• Drive links: 80 — sized for 20" bars

What maintenance and sharpening features does this chain offer?

Oregon designed the M80 with several user-friendly maintenance features to extend sharpness life and simplify sharpening. Expanded top-plate and depth-gauge filing indicators make it easier to return cutters to correct geometry, while the blued cutter finish adds corrosion resistance between uses.

• Top-plate and depth-gauge filing indicators for accurate sharpening
• Blued cutters for surface corrosion protection
• Micro Chisel profile balances fast cutting and manageable resharpening

How does LubriTec help chain and bar longevity?

LubriTec is Oregon’s built-in lubrication channel design that helps deliver oil along the bar and chain contact surfaces, reducing friction and wear. When paired with a proper bar and regular lubrication, LubriTec support helps the chain run cooler and lengthens the life of both chain and guide bar.

• Improves oil distribution between chain and bar
• Reduces friction and heat buildup during operation
• Contributes to extended component life when used correctly

Who is this for: The Oregon M80 SpeedCut 20" chain is for professionals and serious homeowners using 38–55 cc chain saws who want faster, lower-resistance cutting with easier maintenance. Choose this chain if you need a narrow-kerf replacement for a 20" bar with .325" pitch and .050" gauge, require a high-quality resharpenable cutter profile, and plan to match it with SpeedCut or other narrow-kerf bars for best results.
