The set is matched to a 3/8" pitch and .050" gauge with 70 drive links, making it suitable for 20-inch guide bar systems. Below you’ll find clear answers to the most frequent buyer questions, plus model compatibility tips and practical details for safe installation and maintenance.

Which saws will this 20" bar and chain fit?

The combo is designed to work with a wide range of domestic and pro-level chainsaw models; Oregon publishes a detailed fit list and part finder to confirm compatibility. Always cross-check your saw's bar length, drive link count, pitch and gauge before purchasing.

• Fits models from Craftsman, Echo, John Deere, McCulloch, Poulan, Skil and similar brands.
• Specifically built for 20" guide bars with 70 drive links, 3/8" pitch and .050" gauge.
• Use the drive link stamp on your old chain or your owner’s manual to verify fit.

How does the chain design affect cutting performance and safety?

The chain uses low-vibration micro chisel cutters that balance clean cutting with easier filing and reduced kickback compared with full-chisel designs. That makes it well suited for users who want dependable performance without constant sharpening or aggressive kickback behavior.

• Micro chisel cutters give consistent chip removal and simpler maintenance.
• Low-kickback profile decreases rebound risk during common cutting tasks.
• Lightweight, durable steel construction helps reduce operator fatigue.

What does LubriTec oiling do and why does it matter?

Oregon’s LubriTec is an engineered oiling system integrated with the guide bar to keep lubricant moving to the chain automatically, lowering friction and wear. Regular lubrication extends both chain and bar life and improves cutting efficiency, so you spend less time replacing parts.

• Delivers oil to the bar groove and nose for consistent lubrication.
• Reduces heat and metal wear for longer service intervals.
• Helps maintain smoother cutting and steadier chain speed under load.

How do I identify the correct replacement chain and bar for my saw?

Match three key specs: pitch (distance between rivets), gauge (drive link thickness) and drive link count. Measure your guide bar length from tip to where it seats in the saw; check the stamped number on your chain’s drive link if available.

• Pitch: 3/8" for this Oregon combo; measure rivet spacing to confirm.
• Gauge: .050" — this is the thickness of the drive link that fits the bar groove.
• Drive links: 70 links for this 20" set — count old links or consult the manual.

Who this is for: The Oregon 20" bar and 70-drive-link chain is aimed at homeowners, property managers and occasional commercial users who need a durable, easy-to-maintain replacement for 20-inch chainsaw setups. It suits saws up to roughly 60 cc where lower vibration, dependable lubrication and a reduced-kickback chain profile are priorities. If you maintain a standard household or light-professional saw and want a direct-fit, long-lasting upgrade, this pairing is a practical, high-value option.
