Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

What makes this chain stand out

The SpeedCut M78 is built to balance aggressive cutting performance with reliable wear, all while fitting a broad range of popular saws. Its 0.325-in pitch and 0.050-in gauge strike a practical middle ground between speed and durability, enabling clean grinds, smoother feed, and efficient wood removal on larger jobs. With 78 drive links, this chain aligns precisely with a 20-inch bar for stable cutting geometry, reducing chain derailment risk and helping you maintain consistent bite depth from start to finish.

Ideal use cases

  • Property maintenance and large-diameter limb cleanup where a 20-inch bar is the go-to size
  • Firewood production, where steady, aggressive cutting speeds speed up processing
  • Professional or seasoned DIY projects that demand dependable performance across multiple saw brands

Why choose SpeedCut M78 over other chains

Unlike generic chains, the M78 is specifically paired for efficiency with a 20-inch bar and 78-link configuration, ensuring predictable tensioning and smooth operation. Its compatibility across top brands—Echo, Husqvarna, Makita, Mastercraft, Solo, Tanaka, and Troy-Bilt—means you can stock a single chain that covers multiple saws in your lineup, reducing downtime and inventory clutter without sacrificing cutting power.

Care, maintenance, and best practices

  • Keep the chain sharp with a proper file or sharpening system tailored to 0.325" pitch. Regular tuning preserves cutting speed and reduces heat buildup.
  • Tension the chain correctly before every cut to prevent derailment and ensure even wear across all drive links.
  • Use clean, high-quality bar and chain oil to minimize friction and extend chain life during heavy use.
  • Match the bar for compatibility: ensure your bar length is 20 inches and the chain is the correct 78-link configuration for best performance.
  • Inspect for damaged drive links or bent sections after heavy cut sessions; replace immediately to avoid unsafe operation.

Choose the Oregon SpeedCut M78 for a reliable, high-performance chain that’s ready to tackle sizeable tasks with a 20-inch bar. Its precise 78-link configuration, 0.325-pitch, and 0.050-gauge design deliver efficient cutting, versatile brand compatibility, and a practical, long-lasting cutting solution for professional and weekend work alike.
