Oregon 20" PowerCut 72EXL Full-Chisel Chainsaw Chain — 70 Drive Links, .050" Gauge

Oregon's PowerCut 72EXL professional full-chisel chainsaw chain is a 20" replacement loop with 70 drive links designed for fast, consistent cutting on Echo CS-590, CS-600 and other D70/E70-compatible bars.

If you need a direct replacement chain for a 20" bar that restores aggressive cutting performance, this Oregon 72EXL 70-drive-link chain delivers a full-chisel profile, 3/8" pitch and .050" gauge. It is the updated EXL series that supersedes the older LGX line, engineered for professional users who want predictable tooth geometry and easier maintenance on mid-to-large saws. The chain comes as a complete loop sized for models specifying D70 or E70 chains and matches Echo CS-590 Timberwolf, CS-600P and CS-620P when fitted to a 20" guide bar.

What is different about the Oregon 72EXL compared with the older LGX chain?

The 72EXL is Oregon's refreshed pro-series design intended to replace LGX. It keeps the same full-chisel cutter profile favored for rapid, clean cuts but includes updated heat treatment and grind consistency for longer life and stable performance under heavy use. If you previously ran LGX chains, the 72EXL installs and rides the same bar with the same drive link count.

• Replaces LGX with updated EXL manufacturing and cutter consistency
• Full-chisel cutters for faster slice-through on clean wood
• Same fitment footprint: 3/8" pitch, .050" gauge, 70 drive links

Will this chain fit my Echo CS-590, CS-600 or other saws?

This 72EXL loop is specified as a 20" chain with 70 drive links and is compatible with Echo CS-590 Timberwolf, CS-600P and CS-620P when those saws use 20" bars. It also fits any brand or model that calls for D70 or E70 chain sizes. Always confirm your saw’s required pitch, gauge and drive link count before ordering.

• Fits Echo CS-590, CS-600P, CS-620P with 20" bars
• Compatible with D70 and E70 chain specifications
• Check your bar and sprocket: 3/8" pitch, .050" gauge, 70 drive links

How does the full-chisel cutter profile affect cutting and maintenance?

Full-chisel cutters have square-cornered teeth that cut quickly and aggressively through clean, straight-grain wood, making them a good choice for production felling and bucking. They require more frequent sharpening than semi-chisel types if you work in dirty or frozen wood, but they restore excellent cutting speed and smooth chip flow when kept sharp. Proper filing angle and depth gauge settings maintain peak performance and reduce vibration.

• Fast, aggressive cutting ideal for production work
• Needs regular sharpening in abrasive or dirty conditions
• Maintains smooth chip ejection when cutters are sharp and balanced

What are the exact technical specs I should verify before purchase?
