Chain Saw Chains

Match three specifications from your saw or old chain: pitch (distance between rivets), gauge (thickness of the drive link), and the number of drive links; you can also consult the chainsaw owner's manual or the sprocket cover for a model-specific part number

Common consumer chainsaws typically use pitches like 3/8" low-profile and .325", with gauges commonly 0.050" (1.3 mm) or 0.063" (1.6 mm); always verify with your saw's specifications before buying

For general yard and firewood cutting, a full or semi-skip chain is recommended—full chains cut smoothly and are good for consistent cuts, while semi-skip reduces clogging and is useful for larger-diameter or dirty wood; full-skip chains are faster but are typically used for professional, high-feed work

Chain life varies with use and maintenance but can last from a few months to several years; extend life by keeping the chain sharp, maintaining correct tension, lubricating the bar and chain, avoiding hitting dirt or nails, and storing the saw properly

Sharpen when cutting becomes slow, requires extra pressure, or produces fine sawdust instead of coarse chips; replace the chain if cutters are damaged, teeth are worn beyond safe filing limits, or if the chain shows stretched links or broken drive links

Many users can safely sharpen chains with a round file and guide or a handheld/electric sharpener by following tooth angle and depth gauge specs, but professional sharpening or replacement is advisable if you lack tools or if cutters are heavily damaged

Look for chains with proper specification matching your saw, consider reduced-kickback designs if you need lower kickback, and ensure the chain is manufactured to industry standards for materials and heat treatment; always follow the chainsaw manufacturer's safety recommendations
