Ingco 18-Inch (450mm) Professional Replacement Chainsaw Chain - 72 Drive Links, 0.325" Pitch, 0.058" Gauge High-Performance Saw Chain (AGSC51801)

Using a dull, stretched, or low-grade saw chain turns logging and timber management into a slow, hazardous task. Worn chains force you to apply excessive downward pressure on your machine, causing rapid bar friction, engine overheating, and uneven cuts that veer off alignment. Worse yet, an unmaintained chain significantly increases the risk of violent kickback injuries on the job site. The Ingco AGSC51801 18-Inch Professional Replacement Chainsaw Chain is an industrial-grade forestry accessory engineered to deliver aggressive, paper-smooth wood chip clearance and long-lasting edge sharpness. Outfitted with a premium 72 drive link structure, this highly resilient replacement loop allows tree surgeons, land clearers, and firewood processors to slice through thick trunks, structural logs, and dense hardwoods with absolute control.

The elite cutting speed and immense structural life of this chain stem from its hard-chromed semi-chisel cutter geometry. This specialized metallurgical configuration stands up beautifully against abrasive dust, resinous saps, and dense wood grains, retaining its sharp bite significantly longer than standard steel alternatives. Its 0.325" chain pitch paired with a 0.058" (1.5mm) gauge profile ensures smooth, low-vibration operation at maximum engine RPMs, reducing hand-arm fatigue during long outdoor work shifts. Precision-engineered to channel bar oil straight to the vital rivet joints, the chain minimizes thermal friction stretch, ensuring a perfectly tensioned fit. Packed securely in protective double-blister casing, it arrives factory-sharp and job-ready to restore your chainsaw's peak performance.

Key Features

• Hard-Chromed Cutter Links – Semi-chisel cutters deliver rapid, low-friction slicing through both softwoods and dense hardwoods while retaining their razor edges under heavy heat.

• Low-Vibration 0.325" Pitch Layout – Optimizes cutting speed and engine weight distribution, making it exceptionally smooth for heavy logging and timber sectioning.

• Exact 72 Drive Link Matrix – Specifically measured 72-link layout fits standard 18" guide bars perfectly to eliminate chain slack, skipping, or derailing.

• Advanced Internal Oil Delivery – Built-in oil holes and channel pathways help pull guide bar lubrication across the entirety of the chassis rivets, extending overall service lifespan.
