Why Choose Tsumura Premium Bars?

Tsumura bars are laser-cut and CNC-finished to provide the most consistent tolerances in the industry.

• SKS-51 Steel: Provides superior hardness and rail longevity compared to standard laminated or softer steel bars.
• Precision Oil Holes: Engineered to ensure maximum oil flow to the chain chassis even at the high RPMs of modern saws like the MS 500i.
• Replaceable Tip: The premium sprocket nose allows the user to replace only the tip in the event of a bearing failure, significantly extending the life of the bar body.

Chainsaw Bar | Tsumura Light and Tough | Professional Performance
Premium Japanese-Crafted Chainsaw Bar for Professional Durability
Experience exceptional strength and precision with the Tsumura Light and Tough Chainsaw Bar - crafted in Japan
using advanced manufacturing techniques and premium materials. This professional-grade guide bar delivers the
perfect balance of durability and performance that serious professionals demand for challenging cutting tasks.

Superior Japanese Engineering & Craftsmanship
What sets Tsumura bars apart is the proprietary salt bath heat treatment process that achieves an ideal balance
of toughness and hardness in the steel. Unlike conventional methods that heat steel rapidly to over 800°C,
Tsumura's gradual heating approach creates a superior steel structure that maintains its integrity even under extreme conditions. The result is a bar that resists bending, warping, and rail spreading significantly better than
standard bars, delivering longer service life and more precise cutting performance.

Professional-Grade Features That Make the Difference
Premium SKS-51 Steel Construction: One-piece solid high-carbon steel provides exceptional strength and
durability for demanding professional use
Proprietary Salt Bath Heat Treatment: Creates the perfect balance of hardness and toughness for superior
wear resistance and longevity
Precision Laser-Cut Manufacturing: Ensures exact specifications and consistent rail dimensions for
smoother chain operation
Replaceable Sprocket Nose with Grease Point: Extends bar life by allowing replacement of the most wear prone component and proper bearing lubrication
Optimized Oil Flow Design: Ensures proper lubrication throughout the bar to reduce friction and heat buildup
Reduced Vibration Technology: Engineered for smoother operation and improved control during cutting
Professional-Grade Balance: Designed for optimal handling and reduced operator fatigue

The Professional's Choice for Demanding Applications
There's a reason Tsumura remains the preferred choice for professionals using high-powered chainsaws in
demanding environments. When your livelihood depends on your equipment, you can't afford downtime or
inconsistent performance. The exceptional durability and cutting precision of Tsumura Light and Tough bars
translate to more productive cutting time, reduced maintenance, and lower long-term costs - critical advantages
for professional loggers, arborists, and forestry workers.
