Stihl Hexa filed Round. Is the shape better?
Рет қаралды 285
Күн бұрынAn attempt to see if there is an advantage to the shape of the Stihl Hexa cutter or if its cutting speed comes from the narrower kerf. I dramatically changed its shape in the hope of seeing a big change and nothing happened.
It's a good chain, the file is good. Its shape makes sharpening easier for most people and I would recommend it, but I cannot find an advantage or disadvantage to its actual shape. If someone can, please let me know.
Dolmar 7900, 66DL bar, 2 original Stihl Hexa chains, 3/8 8 tooth sprocket.

Great little vid. Nice to see cuts that make for a fair comparison, thank you. So, no significant difference in your test. I've seen a couple of vids showing freshly ground full chisel is slightly faster than Hexa out of the box. I assume you're aware that _"Chainsaw Users"_ has found Stihl Hexa a little faster in Iron Bark, i.e. very hard wood. It seems the Hexa angles give an advantage in very hard woods but even with your conservative round file angles a regular full chisel with round file was sufficient to match Hexa with a powerful saw. It seems the main advantage of Hexa is for ease of getting angles that work well across the board (and Stihl gets to sell plenty of files.) Hexa is an elegant way of simplifying sharpening, I love the knowledge and thought in it. Many go through a long learning process before they can get chain durably sharp - I did. Hexa eliminates that process and chainsawing with a durably sharp chain takes using chainsaws to a much more satisfying place - it's a game changer. Thanks again for the vid Cheers sincerely d

I'm a fan of Hexa because of the design of the file and how much easier it makes sharpening. I'm just not convinced the shape helps its cutting ability and at this stage I have been unable to prove it one way or the other. I think its slightly narrower kerf helps the cutting speed a lot more than the shape but could be wrong. Time will tell It's overall design makes it better for everyone that uses a full chisel and when I buy more 3/8 063 FC, it's what I will buy. I bought a few different semi chisels, Stihl RM, Husky S85 and Oregon DX so that's the next thing I will test. I'll see how they compare to their full chisel equivalent (RS,C85,EXL) and if we can speed them up a bit. Should be done in the next week or 2 if the weather plays ball.

Did you use a progressive depth gauges on both chains before the test

Yep, the Stihl one

What did you mean by that dramatic shape change? Round filing of Hexa?

Yes. Changed its side plate from the Hexa shape to that round file one in the pic. 25/60/60 in its original shape, 25/80/60 after I made it round. Was hoping to see some difference but it cuts and feels the same

@@SawChainTheories Thanks for confirming what seemed very likely, given how the cutting edges are shaped in both cases.

@@elpolaco7654 I should have made it clearer. Both chains are real Hexa and I filed one round to see if the Hexa shape had any advantage. Completely changed it, cuts the same. I'm not really sure what that means or what to try next. I really expected something to happen
