Chainsaw chain Nenurodyta Oregon SemiChisel 91P 3/8" for 18" (45 cm) bars

Replacement chainsaw chain compatible with Oregon SemiChisel 91P specification in 3/8" pitch for 18" (45 cm) guide bars. The chain features a semi-chisel cutter profile designed to provide a balance between cutting speed and resistance to dulling when working with various types of wood. This item is offered as a customer-returned Ecost product; check compatibility with your chainsaw bar length, pitch, and drive link count before installation.

Advantages

The semi-chisel cutter profile offers reliable cutting performance and improved durability compared with full-chisel designs in dirty or resinous wood. The 3/8" pitch and design matched to 18" (45 cm) bars ensure proper engagement with common guide bars and sprockets for general-purpose forestry and garden work. As a replacement chain manufactured to the Oregon 91P profile specification, it provides predictable chain geometry for easier maintenance and sharpening routines.

How to use

Confirm that the chain pitch, drive link count and bar length match your chainsaw specifications before fitting. Fit the chain to the guide bar and sprocket according to the chainsaw manufacturer’s instructions, ensuring correct tension and lubrication. After installation, run the saw at low speed to check alignment and chain movement, then perform a test cut on a small piece of wood to verify cutting performance. Keep the chain tensioned within the recommended range and maintain proper chain oiling while operating.

Usage recommendations

Regularly inspect for wear, damage, or missing teeth and sharpen the semi-chisel cutters with appropriate files following the 91P profile to retain cutting efficiency. For dirty, frozen, or resin-coated wood, reduce feed pressure and perform more frequent sharpening. Store the chain clean and lightly oiled when not in use to prevent corrosion.
