Tsumura Chainsaw Bar - 20", 3/8"-.404", .063", Hardnose, D009

SKU = 20-17-063-PH, 428HT4

Product Overview

The Tsumura 428HT4 is a professional Solid Hard Tip (Stellite-tipped) chainsaw bar. At 20 inches, it is the ideal "stumping" and "dirty wood" bar for Husqvarna large-mount saws. Milled from a single piece of SKS-51 Japanese steel, it is designed to thrive in environments that would destroy a standard sprocket nose.

By eliminating the nose sprocket and bearings, Tsumura has removed the primary failure point for arborists working in sandy soil, fire-damaged timber, or abrasive hardwoods. This bar offers maximum durability for professional users who prioritize reliability over high-speed bore cutting.

Why Choose Tsumura Hard Tip Bars?

• Zero Maintenance: No sprocket bearings to grease or replace, making it the most "set-and-forget" bar in the Tsumura lineup.
• Pitch Versatility: This bar natively supports both 3/8" and .404" chain without any nose modifications—perfect for professionals who switch between chain types for different tasks.
• Superior Heat Sink: The solid steel construction and Stellite nose dissipate heat more effectively than laminated or sprocket-nose bars during heavy-duty bucking and felling.
