There are 3 types of Sugihara Guidebar – Pro Laminated, Pro Solid and Light Type pro. Have a look at the second picture above in the gallery to see how these bars differ.

What makes a Sugihara bar so good? This is a difficult question to summarise easily.

Sugihara bars started manufacturing chainsaw bars in 1967 by Hideo Sugihara. Japan has always had a reputation for excellence forging and working steel. Having the knowledge to manufacture quality chainsaw bars is not something that is gained overnight. It is a complex process of which cutting out the initial bar is only one part.

Steel has different properties dependant on how it is heated then cooled. Sugihara bars may go through the process of heating and cooling up to 4 times on different parts of the bar in order to gain maximum performance. The rails need to be accurately cut and hardened but over hardening can make them brittle. The bar body needs to be stiff yet flexible. We have used a number of different chainsaw bars over the years including all the major manufactures. Sugihara bars are the hardest wearing bars out there. Even their laminated bars will outlast rivals.

On the single piece pro and light type bars the hardness of the rails is measured at HRC 60. Compare this to Stihl at HRC 57 and Oregon at HRC 55 and it is clear why these bars last longer. They are so hard they resist most flat files when it comes to bar dressing (we recommend a diamond dressing knife which can be found here).

However bear in mind they are more ‘thoroughbred’ in that if they are mistreated and the bar gets over heated they are more prone to chipping. In the wrong hands these bars have a far shorter lifespan so please be aware of your bar maintenance:

  1. Check your drive rim/drive sprocket BEFORE you buy a new bar – if worn you MUST change this before running a brand new high tolerance bar

  2. Old chains [yes if they have a been used ‘a few’ times this counts as old – must NOT be run on a new bar [or you can but you will likely wear the bar much faster]. If in doubt do not do it.

  3. DO bed in your new bar and allow all the different parts to begin the bedding in process

Sugi Pro Lam bar review.

Well, not really had it long so I can't give a full review yet. Just hoping it out lasts the stihl rollermaticE as I seem to be burning through them at an alarming rate.
As far as weight goes it doesn't feel any different to Stihl but I wasn't expecting that from this one.
The oil hole is bigger on the sugi than the stihl. That's good I guess. There's also an oil/greece hole for the nose sprocket, to be honest I'm not sure if there's much benefit for this or a possible hindrance if it fills with material. No issues so far though after a couple weeks of use.
So I can't say anything about the longevity I'm afraid.
So, it's a bar, it fits me saw, does the whole spinney thing as it should, it says sugi hara on it which makes me feel posh with a sense of individualism, even though its way cheaper than Stihl's made of laughing cow cheese bar!

Sugihara bar

This bar has just finished a week of forestry work and has performed very well, very well balanced on an ms261 and shows no signs of wear, will buy again
