Oregon 20" Chainsaw Chain — 3/8" LP .050" Gauge, 72 Drive Links, Full Chisel

Oregon 20" chainsaw chain with 3/8" low-profile pitch, .050" (.013" / 1.3 mm) gauge and 72 drive links — a direct-replacement chain engineered for a wide range of 20" bars.

This replacement saw chain is built to match chainsaw models that require a 3/8" low-profile pitch, .050" gauge and 72 drive links for a 20" guide bar. Oregon designs and manufactures chains to fit many popular consumer and professional saws; however, verifying your chainsaw's bar length, drive link count, pitch and gauge before ordering ensures correct fit. The chain is intended for 50–100 cc machines and is suitable for routine cutting, limbing and milling tasks when paired with the proper saw.

Will this chain fit my chainsaw model?

To confirm compatibility, check four key measurements on your current chain or in the saw manual: pitch, gauge, drive link count and bar length. This Oregon chain uses a 3/8" low-profile pitch, .050" gauge and includes 72 drive links for use on a 20" bar. It is commonly compatible with many Stihl, Husqvarna, Makita, Poulan, Echo and other models listed by manufacturers.

• Pitch: 3/8" low-profile (LP)
• Gauge: .050" (1.3 mm) guide bar slot
• Drive links: 72
• Bar length: 20" (50 cm)

How does this chain perform compared with other replacement chains?

This Oregon chain is built with full chisel cutters for efficient, aggressive cutting and offset depth gauges to reduce the risk of the cutter biting into the sidewall of the kerf. Oregon’s manufacturing standards and heat treatment process produce durable cutters and consistent pitch, so you can expect repeatable cutting performance when properly sharpened and maintained.

• Full chisel cutters for faster, cleaner cuts on green and seasoned wood
• Offset depth gauges for smoother feed and reduced kickback tendency
• Heat-treated components for wear resistance and edge retention
• Engineered to meet OEM replacement numbers for simple swaps

What maintenance does this chain need to keep its performance?

Maintaining chain sharpness, correct bar and chain oiling, and proper tension are key to safe, efficient cutting. Sharpen the cutters when they become dull, inspect drive links for wear or damage, and keep the sprocket and bar rails clean to extend chain life. Always follow manufacturer safety and maintenance guidelines for your chainsaw.

• Sharpen cutters with the correct file diameter and filing angle
• Check and adjust tension before each use
• Use appropriate bar and chain oil and clean the oiling port
• Replace chain when drive links or cutters are excessively worn
