Stihl 18" Chainsaw Chain .325 Pitch 74-Link Rapid Super, 0.063" Gauge — Full‑Chisel Professional Cutting

Stihl 26 RS 74 is a professional-grade Rapid Super full-chisel chainsaw chain built for fast, precise cutting on 18" guide bars.

This replacement chain is engineered for demanding forestry and landscaping work where speed and consistent performance matter. With a 0.325" pitch and 0.063" (1.6 mm) gauge, the 74-drive-link configuration fits select mid-size Stihl guide bars and is optimized to clear chips quickly and resist wear under heavy use. Before ordering, verify your chainsaw's specifications to ensure compatibility.

How does this chain improve cutting speed and efficiency?

The Rapid Super full-chisel cutters have square-cornered teeth that slice wood fibers aggressively, translating into faster cuts compared with semi-chisel designs. This sharper profile reduces the number of passes needed to cut through logs and limbs, saving time on prolonged jobs.

• Full-chisel tooth geometry for higher bite and rapid penetration
• Enhanced chip ejection to keep the cutting path clear
• Designed for sustained high-speed cutting in hardwoods and softwoods

Will it fit my Stihl chainsaw and 18" guide bar?

This chain uses a 0.325" pitch, a 0.063" gauge, and contains 74 drive links; it is intended for compatible mid-sized Stihl saws and guide bars built for those measurements. Compatibility varies by model, so cross-check your saw's manual or the bar stamping to confirm fit before purchase.

• 0.325" pitch matches many mid-size Stihl guide bars
• 1.6 mm / 0.063" gauge for compatible bar groove widths
• 74 drive links — verify link count against your current chain

How durable is this chain under professional use?

Manufactured using premium steel and heat-treatment processes, the chain is built to withstand frequent cutting and resist premature dulling. The construction focuses on longevity while maintaining the aggressive cutting profile users expect from a Rapid Super series chain.

• Hardened cutters for improved wear resistance
• Robust rivets and drive links to tolerate heavy loads
• Optimized metallurgy to balance sharpness and life span

What maintenance and sharpening considerations are there?

Because full-chisel teeth cut quickly, they can dull faster when used on dirty wood or in abrasive conditions; regular inspection and timely sharpening will restore peak performance. Use the correct round file diameter and filing angle specified for 0.325" pitch full-chisel cutters, and check rivet tightness and stretch periodically.

• Sharpen with the proper round file and guide for full-chisel cutters
• Inspect for chip buildup and clean bar groove and oil ports
• Replace the chain when rivets wear or pitch/gauge compatibility is compromised

Who is this chain best for? Professionals and serious enthusiasts who run mid-sized Stihl chainsaws for cutting timber, limb work, or property clearing will benefit most from the Stihl 26 RS 74 Rapid Super chain. It excels where fast, precise cutting is required and where operators can maintain the chain properly; casual users or those working mainly on dirty or abrasive materials may prefer a semi-chisel or lower-maintenance option.
