Tsumura chainsaw bars are manufactured and assembled using advanced technology machines and salt heat treatment to provide high standards of durability, strength, finish and accuracy. They incorporate uniform groove gauge tolerances for precise chain fit and improved cutting stability over the bar nose.


Guide bars require both of contrasting characteristics of toughness and hardness. Tsumura has adopted salt heat treatment that draws both of the contrasting characteristics. The salt bath heat treatment is the best way to achieve ideal steel which has toughness and hardness. Normally, Steel is heated over 800°C immediately, but the salt bath heat treatment provides a gradual steady heat method. Then, a good hardened steel structure, which is stable with less distortion, can be obtained.

There are two types of solid guide bar. One has a replaceable sprocket nose and the other has a hard nose. Solid guide bars are manufactured from one plate of super hard alloyed steel SKS-51.

Light Type bars have dove-tailed notches that are staggered and cut into the bar surface and packed with hard resin which reduces the weight of the guide bar by about 20%. This improves cutting efficiency and stability and also reduces user fatigue.

expensive nose

i purchased 2 bars a while ago to go on my 550 , the saw cuts great with them, however the nose gave up on the first bar pretty quickly (a few weeks ) the second has been doing the job now for a lot longer , i thought id buy a replacement nose to make use of the first bar and its £28 for a new one ! almost half the price of a complete one .

Brilliant bar

Swap my husky bar for one of these on my husky 525 climbing saw and what a difference. Putting it mainly down to it having a sprocket nose and the husky bar doesn't that makes so much difference.
Great improvement on the little saw!!!
