Oregon 72EXL 3/8 Inch x 0.05 Inch 100 DL Replacement Saw Chain

Description

Cut clean timber felling lines and process firewood blocks with reduced cutting drag and ultra-fast chain speed. The Oregon 72EXL 3/8 Inch x 0.05 Inch replacement saw chain delivers full-chisel performance across a 100-foot bulk roll. This reshaped chisel chain features optimized tooth geometry. It requires compatible 0.050-inch gauge guide bars on commercial professional chainsaws.

High-tensile alloy steel forms the drive links and cutters, treated with an industrial chrome plating that holds cutting edges through abrasive wood bark. The reshaped full-chisel cutter profile cuts through dense hardwood timber with less feed downforce and faster chip clearance than standard chisel chains. Blued steel tie straps resist tensile stretching under aggressive timber bucking loads. Patented LubriTec oiling channels route bar oil straight to rivet joints, reducing frictional wear.

Key Features of Oregon 72EXL100U

Arborists and logging contractors use this 100-foot bulk reel to spin custom loops for felling saws and firewood bucking bars. The reshaped chisel teeth require less operator push downforce.

• 100-foot bulk chain reel containing 1640 drive links spins dozens of custom chainsaw loops
• 3/8-inch pitch handles commercial engine power on professional timber felling saws
• 0.050-inch drive link gauge seats securely into standard commercial professional guide bars
• Reshaped full-chisel cutter profile cuts through dense hardwood timber with reduced cutting drag
• Offset depth gauges reduce cutting vibration to prevent operator fatigue during long cuts
• LubriTec reservoir channels route bar oil to chain rivets to extend bar and chain life
• Includes bulk breaker preset links and connecting tie straps for spinning custom loops

Chainsaw Chain Cutting Dyno Telemetry

Dynamometer cut tests confirm cutting speeds of 6300 FPM at 9800 chainsaw engine RPM through 12-inch green oak logs. Chain tensile stretch measures under 0.13 percent after 50 continuous bucking cuts under full bar load. Fuel consumption on 60 cc test saws averages 0.40 GPH during active bucking cycles. Cutter edge hardness measures 63 HRC along the chrome plated cutting plate. Acoustic noise registers 104 dBA.

Chain Spinning Safety Setup Boundaries

Use a professional chain breaker and spinner tool to press rivets squarely when assembling custom chain loops. Verify chain tension on the saw guide bar, allowing 1/8-inch snap clearance between drive links and bar rails. Do not operate this full-chisel chain in gritty root balls or soil-encrusted storm debris.

• Cutter top plates require 25-degree hand filing using a 7/32-inch round chain file
• Depth gauges demand flat filing to maintain 0.025-inch depth clearance every three sharpenings
• Guide bar rails require de-burring with a flat file before installing freshly spun loops

Oregon Saw Chain Reel Warranty Manifest

Oregon Tool backs this 100-foot saw chain reel with a Lifetime limited commercial warranty against material defects and broken link welds. The heavy spool carton contains 100 feet of 72EXL chain, connecting preset tie straps, and packaging.
