Tsumura Light Type 18″ (45cm) 3/8 .058 – 68 Drive Links Chainsaw Bar

Designed for professional chainsaw users who demand lightweight handling, cutting stability and long-term durability. The Tsumura Light Type 18″ (45cm) chainsaw bar is manufactured and assembled using advanced technology machines and salt heat treatment to deliver high standards of durability, strength, finish and dimensional accuracy. Uniform groove gauge tolerances ensure precise chain fit and improved cutting stability over the bar nose.

Guide bars require both toughness and hardness — two normally contrasting characteristics. Tsumura’s salt bath heat treatment process draws out both properties by applying a gradual, steady heating method. This results in an ideal hardened steel structure with excellent stability and reduced distortion.

Key Features & Benefits

• Light Type weight-reduction design: Dove-tailed notches staggered and packed with hard resin reduce bar weight by approximately 20%.
• Salt heat treatment: Produces steel with both toughness and hardness for long-term durability.
• Uniform groove gauge tolerances: Ensures precise chain fit and improved cutting stability.
• Solid guide bar construction: Manufactured from one plate of super hard alloyed steel SKS-51.
• Improved cutting efficiency: Reduced bar weight enhances balance and performance.
• Reduced operator fatigue: Lighter bar design improves handling during prolonged cutting work.

Guide Bar Construction Explained

Tsumura solid guide bars are manufactured from a single plate of super hard SKS-51 alloyed steel. Two styles exist within the solid bar range — one with a replaceable sprocket nose and one with a hard nose. This Light Type bar uses advanced machining combined with resin-packed weight-reduction notches to lower the overall mass without compromising strength.

The salt bath heat treatment method gradually heats the steel rather than applying immediate extreme temperatures. This process creates a stable, hardened steel structure with reduced distortion while maintaining both toughness and hardness — essential characteristics for professional cutting performance.

Why Choose the Tsumura Light Type 18″ Chainsaw Bar?

This Tsumura Light Type bar is engineered for professionals who require durability, accuracy and reduced fatigue during extended cutting sessions. The combination of advanced machining, salt heat treatment and weight-reduction technology delivers excellent cutting stability with improved handling characteristics.

With precise groove tolerances, balanced weight distribution and hardened SKS-51 steel construction, this 18″ bar offers consistent, reliable performance in demanding forestry and arb work environments.
