Oregon Tool S45 Advancecut 12 in Chainsaw Chain Low Kickback

Product Description

The OREGON TOOL S45 is a 12-inch semi-chisel chainsaw chain built for small to mid-size gas saws up to 42 cc. It runs a 3/8-inch pitch and a .050-inch (1.3 mm) gauge, making it compatible across a wide range of consumer and light-duty professional chainsaws. The cutters are hard-chrome plated over a precision heat-treated steel body, which extends edge retention and resists wear from debris-heavy cutting conditions. The S45 features Oregon's Lubri-Tec automatic oiling system, which channels bar oil to critical chain contact points during operation, reducing friction and extending chain life. Low-kickback and low-vibration geometry helps reduce operator fatigue during extended cuts.

The S45 is suited for landscapers, tree service crews, and homeowners running lightweight guide bars on low-powered saws. Typical applications include limbing, firewood cutting, and general yard clearing where a narrow kerf chain on a short 12-inch bar is the practical setup. The chain must be paired with a narrow kerf bar. It is not intended for high-displacement professional saws or milling applications. The design meets ANSI low-kickback standards, making it appropriate for operators who prioritize safety in routine cutting tasks.

Key Features

• 3/8-inch pitch and .050-inch (1.3 mm) gauge fit a broad range of chainsaw brands
• Hard-chrome cutter coating extends edge life and resists wear from dirt and debris
• Precision heat-treated semi-chisel cutters maintain smooth cutting with higher debris tolerance than full-chisel profiles
• Lubri-Tec automatic oiling system delivers oil to key chain contact points during operation
• Low-kickback, low-vibration design meets ANSI standards and reduces operator fatigue
• Hardened rivets and chrome outer layer minimize stretch and reduce the frequency of tensioning adjustments

Compatibility

Designed for all chainsaw brands that run 3/8-inch pitch, .050-inch gauge chain on 12-inch guide bars. Rated for saws up to 42 cc. Must be used with a narrow kerf bar.

Installation Notes

Chain installation and tensioning should be performed with the saw powered off and the spark plug boot disconnected. Use the bar and chain adjustment tool appropriate to the saw model to set proper chain tension — the chain should move freely around the bar without sagging below the rail. Always wear cut-resistant gloves when handling exposed chain. Confirm bar groove width matches the .050-inch gauge before fitting.
