[H4-20] 407FB4-A Tsumura Light Bar Black Edition 20″[50cm] 3/8 .058 72 drive links [ANNIVERSARY PRE ORDER SET ETA 20th MAY 2024]

Tsumura are doing a 100th anniversary collectable set. Each bar will have a serial number on it.

Black edition.

‘No.1,No.11,No.22,No.33,No.44, No.55, No.66,No.77,No.88,No99 and No.100 will be special bars’

I don’t know what will be special about the above bars – but they will be allocated at random.

I’m going to do an NFT that goes with each bar – don’t worry if you are not into that it’s a bonus will make a video later.

I will set up a pre order offer of £100+vat per set – only one set allowed per person [only x100 sets in total on this worldwide – we have x75 sets ear marked for Chainsawbars cause I got in early!].

These are not for using but for collecting.

Tsumura Black Label light bars –  ONLY 20″ large Husky mount for now. Other mounts/sizes may become available Dec 2022 – this is it for now and once these are sold – Yes Dec 2022 before we get more of these again! 200g lighter than the previous incarnation of this bar.

Only one bar allowed per customer [please don’t place multiple orders]. May allow more in the future but these have to last a year…

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.
