Oregon Tool D66 Advancecut Chainsaw Chain 18 in 66 Drive Links

Product Description

The OREGON TOOL D66 is an 18-inch semi-chisel chainsaw chain with 66 drive links, engineered for both occasional and commercial cutting applications. The chain uses full chisel cutters with a patented bent-over depth gauge that reduces vibration and delivers a smooth cut through wood. An outer layer of industrial chrome hardens the cutting surface, and hardened rivets provide a high-strength, load-bearing connection between links. OREGON TOOL's LubriTec system channels oil more efficiently to the chain and bar, reducing wear and extending service life. The D66 is suited to users who demand consistent performance across varied cutting conditions without sacrificing durability.

This chain is designed for chainsaw bars measuring 18 inches and is appropriate for residential, farm, and commercial forestry work. The semi-chisel cutter geometry makes it more tolerant of dirty, dusty, or abrasive cutting environments compared to full chisel configurations. It fits a range of consumer and professional-grade chainsaws that accept an 18-inch bar with a 66-drive-link chain. Typical applications include limbing, bucking firewood, storm cleanup, land clearing, and general arborist work.

Key Features

• Semi-chisel cutters offer improved durability in dirt and dusty cutting conditions
• Patented bent-over depth gauge reduces vibration for a smoother cutting experience
• Industrial chrome outer layer hardens the cutter surface for extended edge life
• Hardened rivets reduce wear, increase load-bearing strength, and minimize tension adjustments
• LubriTec oil delivery system improves chain and bar lubrication efficiency
• Suitable for both occasional homeowner use and demanding commercial applications

Compatibility

Designed as a replacement chainsaw chain for saws accepting an 18-inch bar with a 66-drive-link configuration. Verify pitch, gauge, and drive link count against the existing chain or saw owner's manual before installation.

Installation Notes

Chain installation and tensioning should be performed by a qualified operator following the chainsaw manufacturer's service guidelines. Always disengage the chain brake, disconnect the spark plug wire, and wear cut-resistant gloves before handling the chain. Use the saw's built-in tensioner or a bar wrench set to achieve correct tension — the chain should move freely around the bar without sagging. After initial run-in, recheck tension, as new chains stretch slightly during the first use.
