Oregon Tool M78 Speedcut 20 in Chainsaw Chain

Product Description

The OREGON TOOL M78 is a SpeedCut narrow kerf chainsaw chain designed for 20-inch guide bars on gas-powered chainsaws up to 55 cc. The narrow kerf design removes less material per cut, requiring less power from the saw and improving cutting efficiency. Micro-Chisel cutters feature small-radius working corners that reduce vibration during operation. LubriTec technology continuously lubricates the chain and guide bar to minimize friction and extend service life. Blued cutters provide built-in corrosion resistance for extended field use. This chain is built from OCS-01 steel and is sold individually.

The M78 is suited for residential and light professional chainsaw use where efficiency and low operator fatigue are priorities. It fits 20-inch guide bar setups and is optimized for saws in the 35 cc to 55 cc range. Expanded top-plate filing indicators and depth gauge filing indicators are included on the chain to support accurate field sharpening without guesswork. This chain is appropriate for arborists, landscapers, and experienced users who maintain their own equipment. Always use SpeedCut narrow kerf chain in combination with SpeedCut or Micro-Lite bars.
