Husqvarna 28-inch X-Cut skip-tooth chain C83SK — 3/8" pitch .050" gauge, 93-link square-ground

Husqvarna's 28" X-Cut C83SK is a skip-tooth, square-ground chisel cutting chain (3/8" pitch, .050" gauge) designed for smoother, faster, and more precise cutting on 28-inch bars.

This retail-packaged replacement chain (model 585551493) fits 28" guide bars and contains 93 drive links. Engineered as a skip-sequence chisel cutter, the C83SK reduces the number of cutters to improve chip clearance and lower the power needed to maintain engine RPM. It sharpens with chisel files and delivers consistent cuts compared with standard chains, making it a practical choice for demanding pruning and felling tasks where speed and clean cutting matter.

How does the skip-tooth design affect cutting performance?

The skip sequence spaces cutters farther apart than full-skip or full complement chains, which reduces drag and helps clear chips more efficiently. That means the saw can sustain RPM with less load and the chain runs cooler under heavy use.

• Fewer cutters reduce resistance and improve chip ejection.
• Lower continuous power draw on the engine during heavy cuts.
• Better for larger-diameter wood where rapid chip clearing prevents clogging.

Why choose a square-ground chisel cutter with .050" gauge?

Square-ground chisel cutters have sharp, squared teeth that slice wood cleanly and consistently. Combined with a .050" gauge, this setup balances strength and cutting aggressiveness for faster, precise cuts while remaining serviceable with standard sharpening tools.

• Sharp square edges give quick, consistent bite into wood.
• .050" gauge provides durable cutting performance on tougher jobs.
• Sharpenable with common chisel files for field maintenance.

Will this chain fit my saw and guide bar?

This C83SK chain uses a 3/8" pitch, .050" gauge and has 93 drive links, which is compatible with 28" bars that require that specification. Always verify your saw and bar manufacturer specifications or consult your owner’s manual before installation to ensure correct fit and safe operation.

• Pitch: 3/8" — match to bar and sprocket pitch.
• Gauge: .050" — ensure bar groove accommodates this thickness.
• Drive links: 93 — must match the bar length and saw model requirements.

How should I maintain and sharpen the C83SK chain?

The C83SK is designed for field sharpening with chisel files appropriate to the cutter size. Routine maintenance—correct tensioning, cleaning, lubrication, and timely sharpening—extends chain life and preserves cutting performance.

• Use the recommended chisel file and guide for square-ground cutters.
• Keep proper tension: snug but able to rotate by hand when cold.
• Clean sawdust and sap from the chain and bar groove; lubricate before use.

Who is this for: The Husqvarna 28" X-Cut C83SK chain suits professional arborists, loggers, and serious homeowners who use 28-inch bars and need a robust, sharp-cutting chain that clears chips efficiently and maintains engine RPM under load. If you require faster, cleaner cuts on larger timber and want a chain that can be maintained in the field with basic sharpening tools, this chain is a practical, high-performance replacement option.
