JINFFR 18" Chainsaw Chains 5-Pack .325" Pitch .063" Gauge 68-Link — Semi-Chisel, Chrome-Plated German Steel

JINFFR 5-pack 18" chainsaw chains replace Stihl-compatible .325" pitch, .063" gauge bars with 68 drive links for smooth, durable cutting.

These chains are engineered as direct-fit replacements for many Stihl models that accept an 18-inch bar with a .325" pitch and .063" gauge. Each pack includes five semi-chisel chains made from hardened German steel with Japanese chrome plating for corrosion resistance and long edge life. They are intended for routine cutting, limbing, and general-purpose woodwork—confirm your saw’s pitch, gauge, sprocket type, and drive link count before ordering to ensure compatibility.

How do I confirm these chains fit my Stihl saw?

Check four key measurements on your guide bar or in the owner’s manual: bar length, pitch, gauge, and drive link count. The JINFFR chains in this pack are 18" length equivalents with .325" pitch, .063" gauge, and 68 drive links.

• Look for a stamped number on the bar indicating length and drive links.
• Measure pitch by spacing: three rivet-to-rivet distances divided by two to confirm .325".
• Gauge is the thickness of the drive link; this pack requires .063" (1.6 mm).
• Confirm your sprocket fits .325" pitch and the saw model is listed as compatible.

What cutting performance and durability can I expect?

These chains use high-hardness German steel and chrome plating to resist wear and corrosion while maintaining a sharp edge. The semi-chisel cutter profile balances aggressive cutting with lower kickback and longer intervals between sharpenings.

• Semi-chisel cutters for efficient wood removal and slower dulling.
• Chrome plating helps resist rust and reduces friction in damp conditions.
• Manufactured to ANSI influence for predictable kickback behavior.
• Five chains provide multiple replacements for heavy or repeated use.

Are these chains safe and easy to install?

Installation follows the same steps as most standard saw chains: release tension, fit the chain around the bar and sprocket, then re-tension and lubricate. The semi-chisel design and consistent manufacturing tolerances make alignment straightforward; always follow your chainsaw manufacturer’s safety guidance.

• Fit around the sprocket and bar nose before tensioning.
• Adjust tension with the chainsaw’s tension screw until the chain snaps back under slight pull.
• Always use bar oil and check chain tension after the first few cuts.
• Wear PPE and follow manufacturer safety instructions during installation and operation.

Which Stihl models are these intended to replace?

This 5-pack is made for Stihl saws that accept an 18" bar with .325" pitch and .063" gauge. Common compatible models include MS230, MS230 C, MS250, MS250 C, MS251 and their C/BE variants, plus older 025 series models. Note: some 2022+ MS250 units may use a .050" gauge—verify gauge before purchase.

• Fits: Stihl 025, MS230 series, MS241C-M, MS250 series, MS251 series.
• Not suitable if your bar is stamped .050" gauge or uses a different pitch.
• Confirm your saw uses a .325" sprocket to avoid drive mismatch.

Who is this for: The JINFFR 5-pack is intended for homeowners, arborists, and professional users who operate Stihl-compatible saws and want multiple replacement chains on hand for frequent cutting jobs. It’s a practical option for anyone who needs reliable, affordable chains that balance cutting speed and edge life—just make sure the pitch, gauge and drive link count match your bar before ordering.
