Fifchall 18-inch Chainsaw Bar + 3 M72 Chains (.325" pitch, .050" gauge) — Fits Husqvarna Models, Heat-Treated Semi-Chisel

The Fifchall 18-inch chainsaw bar with three M72 .325" pitch, .050" gauge chains is a durable replacement kit designed to fit many Husqvarna and other popular saw models for reliable cutting performance.

This complete combo bundles one precision-machined 18" guide bar and three heat-treated semi-chisel M72 chains (72 drive links) so you can replace a worn bar or keep spare chains on hand. The components are engineered for long wear, smoother feeding and reduced kickback while matching common OEM specifications; the kit comes coated with protective oil and is ready for fast installation.

Which saw models and sprockets does this 18" Fifchall combo fit?

The kit is compatible with a wide selection of Husqvarna models (including 435, 440, 545, 345, 350, 51, 55 Rancher, 550XP and many earlier and current chainsaws) and several other brands provided the saw uses a .325" sprocket and the specified bar length. Always match pitch, gauge and drive link count to your saw’s requirements before purchasing.

• Pitch: .325" — ensure your sprocket matches this pitch.
• Gauge: .050" — fits .050" guide bars and nose fittings.
• Drive links: 72 — count your current chain for exact fit.
• Bar length: 18" — measure tip-to-tip along the bar's top.

How does the Fifchall bar and chain deliver smoother, longer cuts?

The bar is built from high-strength alloy for improved wear resistance and a stable guide plate, while the M72 semi-chisel chains are heat-treated to keep cutters sharp and durable. Together they promote consistent cutting, reduce friction thanks to the bar’s lubrication channel, and maintain cutting pace even under heavier use.

• High-strength alloy bar resists bending and wear.
• Heat-treated semi-chisel cutters hold edge longer.
• Efficient lubrication channel lowers running temperature.
• Hardened rivets extend chain life and reliability.

What should I expect when installing and maintaining this replacement set?

Installation follows the same steps as OEM parts: align chain, tension to manufacturer spec, and ensure sprocket compatibility. Chains arrive lightly oiled to prevent corrosion; routine maintenance like proper tensioning, regular sharpening and lubrication will maximize life and safety.

• Chains come pre-coated with protective oil for corrosion resistance.
• Adjust tension after warming up the engine for accurate setting.
• Sharpen semi-chisel cutters as needed for efficient cutting.
• Check clutch sprocket and nose sprocket compatibility first.

Why choose a 3-chain plus bar combo instead of single replacement parts?

Stocking multiple chains with one robust bar reduces downtime during extended cutting jobs and gives you interchangeable spares when a chain dulls or is damaged. Buying the combo can be more cost-effective than sourcing each part separately while ensuring matched fitment and performance from the same manufacturer.

• Three ready-to-install chains keep you cutting longer between maintenance stops.
• One bar sized to common 18" applications simplifies compatibility checks.
• Uniform chain specs avoid mismatched cutting behavior.
• Packaged protection oil prevents rust in storage and transit.

Who this kit is for: homeowners, landscapers and professional users who operate Husqvarna and compatible saws with a .325" sprocket and need an economical, ready-to-use replacement solution. If you remove a lot of wood, work in remote locations, or want spare chains for uninterrupted projects, this Fifchall 18" bar plus three M72 chains kit is a practical fit. For precise fitment, verify pitch (.325"), gauge (.050"), drive links (72) and bar length (18") against your saw’s manual before ordering.
