Advanced Salt Heat Treatment

Tsumura guide bars use specialist salt bath heat treatment technology to gradually heat the steel structure rather than rapidly heating it at extreme temperatures. This process helps create a more stable hardened steel structure with excellent durability and reduced distortion.

Strong & Durable Alloy Steel Construction

Solid guide bars are manufactured from premium SKS-51 alloy steel for maximum strength and durability during demanding professional cutting applications.

Precise Chain Fit & Stability

Uniform groove gauge tolerances help maintain accurate chain fitment and improved cutting stability across the full length of the guide bar.

Light Type Guide Bars

Tsumura Light Type guide bars feature staggered dove-tailed notches packed with hard resin to reduce overall bar weight by approximately 20%.

This lightweight construction improves handling, reduces operator fatigue and helps improve overall cutting efficiency during prolonged use.
