Tsumura Chainsaw Bar - 30", 3/8"-.404", .063", Premium Hard Nose, E099

SKU = 30-57-063-PH, 334HT4

Product Overview

The Tsumura 334HT4 is a premium Solid Hard Tip (Stellite-tipped) chainsaw bar. Designed for 30-inch heavy-duty felling and milling, this bar is crafted from a single piece of SKS-51 Japanese steel.

By utilizing a laser-welded cobalt-alloy (Stellite) nose instead of a sprocket, Tsumura has created a bar that is immune to bearing failure. This makes it the ultimate choice for Australian arborists and loggers working in "dirty" wood, fire-salvage, or abrasive conditions where standard sprocket noses often seize or fail.

Why Choose Tsumura Hard Tip Bars?

• Zero Bearing Failure: The absence of a sprocket nose ensures that the bar will not fail due to grease-starvation or debris ingress in the tip.
• SKS-51 Strength: The Japanese steel provides exceptional rail hardness and flexibility, allowing the bar to track straight even under the high tension of a 30-inch chain.

Milling Superiority: The solid-nose design is the preferred choice for chainsaw milling (Alaskan mills), as it handles the constant heat and pressure of longitudinal cuts better than any sprocket nose.
