Oregon Tool M66 Speedcut 16 in Chainsaw Chain

Product Description

The OREGON TOOL M66 is a narrow kerf chainsaw chain designed for efficient cutting with reduced power demand from the saw. Built for saws up to 55 cc, it uses Micro-Chisel cutters with small-radius working corners that lower vibration during operation. The chain is constructed from OCS-01 steel with blued cutters that resist corrosion. LubriTec technology continuously oils the chain and guide bar to minimize friction and extend service life. Licensed chainsaw operators and tree care professionals working with compatible saws will find this chain a direct fit for routine cutting tasks.

The M66 is suited for residential and light commercial cutting applications where a 16-inch bar setup is appropriate. Its narrow kerf design reduces the amount of material removed per pass, requiring less engine power to drive the chain through the cut. This makes it a practical option for mid-range gas saws in the 40 cc to 55 cc class. The expanded top-plate filing indicators and depth gauge filing indicators allow for accurate field sharpening without specialized equipment, supporting consistent cutting performance over the chain's service life.

Installation Notes

Chain installation should be performed by a qualified operator with the saw fully powered off and the spark plug wire disconnected.
