Stihl DURO chain - round file

[Evansaw]

Hi all there

Happy Eastern best wishes to you and yours.

Accidentally i came across something that might be useful to the members.

For Stihl's DURO chain with Carbide Cutters I found there is a round file available. I don't know anything more other than the basic description of the store located in Germany. So no manufacturer or if available across Atlantic.
In my country sharpening a Duro chain is expensive at 5 euros per chain usually 20inch. They rarely price more a bigger chain. So the round file with cost of 20€ might worth more than the 4 store sharpenings.

It is what it is...so might be useful to you guys

Interesting.

4.8mm will NOT fit into the stock factory gullet of a Stihl Rapid Duro nor Stihl Picco Duro.

Ask me how I know.

I got 5.5mm diamond laced files off eBay, three different grits.
They are not working for what I had high hopes they would be good for.

I have no further information about those files. Not even if they come in different sizes.

I bought some from the farm and fleet store my wife works at in forester packages but haven’t used them yet to even see it they work

I saw those and was wondering if I should get some.. have you tried them with normal chain, or did you just try the carbide chain

Diamond isn’t recommended for standard chain just carbide

I tried the medium and fine diamond file on regular chains, they take off too little material per stroke to make them worth the trouble.

The coarse file is way too rough, I haven't found a use for it so far.
