is there a good narrow kerf standard mount bar for stihl?
« on: November 13, 2011, 01:53:58 pm »
I got the microlite pro, (now name changed to Pro-lite Plus), and put it on my 361 with a 9 tooth sprocket, only one available. It cut like crazy, and smooth as silk, but within two or three tanks, the bar groove had worn wide, and the chain flops to the side in soft wood. Even a brand new chain slops side to side in the bar. My Husqvarna branded narrow kerf bar has no problems like that; I've been using them for six months on a 346. The Stihl is using enough oil. I came across this one other time with a cheaper bar. Is there a good narrow kerf bar for the Stihl standard mount?

No, 9T .325. I'm pretty sure narrow kerf setups come only in .325.

I have no clue. Never ran a saw or seen a saw with narrow nerf.  What exactly is it?

I did get a trim saw with .043 stuff and I pulled the whole set up off.

I've heard narrow kerf referred to but I've never seen one in person or in pictures.
So I'm assuming the teeth of the chain are narrower than standard, and running .325 x .050 gauge
Is the width of the bar itself narrower too?

I was hoping the OP would shed some light on this so us unknowing types had a clue.

So what is this narrow kerf stuff?  Info man info.................................... ::)


Just searching for info to try and understand.

narrow kerf technology. Narrow kerf saw chain makes your chainsaws cut faster with less power, because both the bar and chain have been streamlined to a thinner size.

Works with the following Chainsaw Chain:

    * Husqvarna H30, S30
    * Oregon 95VP
    * WoodlandPRO 20NK

Tried narrow kerf, don't like it for 2 reasons.
Chain is not chisel style and not tough enough for my type of work.
95VP is the best of the lot.

As far as bars go, I have never found a good narrow kerf bar for Stihl.

Thanks for your replies, everyone. Hadn't checked here for a few days. Yes, narrow kerf chain cuts a narrower band of wood than the standard .325. The bars are also narrower. I was using a 361 with lgx 3/8 .50, then switched to the 346 with narrow kerf 95 vp and 95 vpx, (the low vibe version of 95vp). In a 14 inch aspen cut the 346 was three seconds slower than the 361 (13 and 16 seconds), and that was little enough time lost for me to switch to the smaller saw. (I haven't done a timed cut between a 3/8 standard and .325 narrow kerf on the same saw, but just in general, the 361 seemed much faster and smoother with the narrow kerf than the 33rsc (3/8) Stihl chain.) The narrow kerf setup weighed .7 lbs less than the 3/8 setup. The chains last me about three weeks compared to the 3/8 at about ten days in use of about six to seven hours a day. Considering the weight difference between the 361 and 346, the whole saw and narrow kerf setup was two pounds lighter than the 361 3/8 setup. So, I didn't have the same experience as Old Iron. I really like the chain, and the Husqvarna narrow kerf bars hold up fine, but would like to find a good quality narrow kerf  bar to run on the Stihl. It looks like I'm maybe out of luck because the Oregon Microlite bars, as I mentioned in the original post, don't hold up.

I have found the best application for the narrow kerf .325 H30 / Oregon 95VP is on my 2 top handle saws, Husky 338XPT and Stihl MS200. The beauty about the 338XPT .325 setup is it has a rim sprocket , the MS200 only has a .325 spur drum available.
I use the Husqvarna narrow kerf bars on both the 200 and 338.
I prefer the micro chisel [semi chisel] as a work chain. Holds a excellent edge for the long run. I have tried the H30 / 95VP on my 346XP and found it was more agressive and "seemed" to cut faster then the chisel 20LP. Now Oregon has introduced the 95VPX with more efficent top plate angles and is said to cut 15% faster then the old 95VP.
For the "bigger" Stihl 361 why not just use .325 20LP with 9 pin and forget about the narrow kerf setup?
