Eliminate bogging in big timber, excessive kerf drag, slow cutting times, and dull cutter teeth on your heavy-duty commercial chainsaw. This Genuine Echo Factory OEM 20" Professional Chainsaw Chain (Part Number 72LPX72CQ) is the authentic high-performance full-chisel cutting loop engineered explicitly for the Echo CS-7310P and CS-7310PW commercial timber chainsaws running 20-inch guide bars. Operating a large-displacement commercial saw with an undersized, low-kickback consumer chain prevents the engine from utilizing its full 73.5cc torque, generating excessive bar-rail heat and turning clean wood into fine dust rather than thick, fast-clearing chips.
Engineered for professional production fallers, the 72LPX72CQ chain features high-output full-chisel square-corner cutters that shear clean wood fibers with minimal resistance and maximum severance speed. Built on heavy-duty 3/8" pitch chassis with an industry-standard .050" gauge and 72 drive links, it incorporates LubriTec™ oil-reservoir tie straps and drive-link channels that keep bar oil routed directly to high-friction bearing surfaces, reducing chain stretch and extending guide bar life. The offset depth gauges prevent cutter grab and reduce vibration without the intrusive safety bumper links that slow down commercial bore cuts and felling hinges.
This authentic factory replacement chain loop is cataloged under Echo OEM Part Number 72LPX72CQ (72LPX-72CQ / 72LPX 72DL / 20-Inch Saw Chain 3/8" .050" 72 Drive Links / Pro Full Chisel).

100% Genuine Factory OEM Cutting Loop: Engineered to exact Echo commercial specifications for optimal power delivery on high-torque 70cc+ saws.
Aggressive Full-Chisel Cutters: Precision ground square-corner teeth slice clean hardwood and softwood fibers with maximum severance speed and clean chip clearance.

Engineered for Plunge & Bore Cuts: Unobstructed chassis geometry without bumper drive links allows fast, smooth felling hinge bore-cuts without chatter.
High-Carbon Heat-Treated Alloy Steel: Resists high-tension stretch and rivet wear, holding cutting edges sharp through demanding bucking and felling shifts.

🛠️ Pro-Maintenance Tip: Watch the "Square Corner Filing Angle & Non-Bumper Safety Secret!" Full-Chisel Filing Secret: The 72LPX72CQ features a square-corner full-chisel profile. When maintaining cutters with a standard 7/32" round file in the field, hold the file at a consistent 25° to 30° horizontal filing angle and keep 1/5th (20%) of the file diameter above the cutter top plate. Never let the file dip into the gullet, which creates a hooked edge that dulls quickly in dirty bark. Pro Sawyer Safety Notice: Because this is a yellow-label professional chain engineered without bumper drive links between cutters, it offers higher cutting speed but increased kickback potential. Always maintain a firm two-handed wrap grip and stand clear of the kickback danger zone during limb-tip cutting and plunge-cutting maneuvers.
