Tsumura Lightweight Bar - 20", 3/8", .058", Premium Sprocket Nose, D009

Product Overview

The Tsumura 407FK4 is a premium "Light & Tough" professional chainsaw bar manufactured in Japan. Engineered for the Husqvarna Large Mount (D009), this 20-inch bar features Tsumura’s signature weight-reduction technology: staggered dove-tailed notches are laser-cut into the SKS-51 steel body and filled with a specialized hard resin. This reduces the bar's weight by approximately 20%.

For professional operators using high-torque Husqvarna powerheads, this weight reduction provides a significantly better pivot point, making the saw feel lighter and more maneuverable during felling and bucking without sacrificing the rigidity needed for straight cuts in heavy Australian hardwood.

Why Choose Tsumura Lightweight Bars?

• Superior Balance: Removing weight from the bar tip shifts the saw's center of gravity back toward the handles. This reduces the physical effort required to lift and pivot the saw, leading to less back and shoulder strain.
• Resin-Filled Stability: Unlike hollow-core lightweight bars, Tsumura's solid steel body with resin inserts maintains the stiffness of a solid bar, preventing the chain from wandering in deep or off-angle cuts.

Japanese SKS-51 Tool Steel: The induction-hardened rails offer exceptional wear resistance. Tsumura steel is designed to be "tough-hard," meaning it resists chipping and rail-spread even under the high-impact conditions of professional logging.
