Square files, the what and the where?

[Wonkydonkey]

Well, that order sadly got cancelled. They said that the manufacturer had a backorder with no expected fulfillment date.

That really sucks..

Try your local Stihl dealer for this part number:


Please report back. (my dealers suck balls so I won’t bother)

My STIHL dealer (4th generation family owned) said that they never carried them. STIHL catalog just refers them to the triangular / hex files.

About a year ago, I attempted to order the 7010 871 0006 from the dealer that closed by me. When he checked, it subbed to the 7010 871 0132 triangle file for square chain. He ordered a dozen, kept two and I bought the other ten. I think midwest Stihl was discontinuing them.

This apparently is a current part, according to European square file group for Vallorbe made Stihl branded double bevels.
So my question is, did you ask about any double bevel offered by Stihl ever, or did they look up that part number?

STIHL offers a lot of items in other countries, that are not available in the US, even by special order. The stock numbers do not even show up. Just like thle progressive depth gauge tools.

If you ever vacation overseas, or know someone stationed there in the military, it might be worth putting together a list, and visiting a STIHL dealer for a shopping trip.

I had another look at this chain I got.. no prizes as to where it’s from. I took it out the packet for closer inspection today.. after writing what I did above..
This chain is a semi chisel and I thought it had a sq grind on it. So can someone tell me what sort of grind it has on it from the factory
For ref.. it’s a 16” 325 chain

I don’t have the chains at hand but that cutter side profile looks exactly like some semi chisel Archer I bought a couple years back. I commented on how unusual it was and wondered what the grinding wheel would look like and I believe @Philbert commented on how many of the newer aggressive grinds were accomplished on CNC machines using multiple passes at different angles

I kind of think @RI Chevy had some with that same funky sideways chevron grind

File Sharpening?

Folks said that Save Edge used to offer a file sharpening service, but discontinued it. Someone on another forum suggested this company:

https://boggstool.com/file-division

They said that they can sharpen a wide range of file types, but I wonder how that works on the critical corners of double bevel / chisel bit files.

Does anyone have experience with this company? Has anyone tried other file sharpening services and have experiences to share, especially with these kinds of files?

Thanks.

As far as I have ever known all “file sharpening” processes involve dipping the cleaned up file in sulphuric acid for a period of time followed by rinses in a bicarbonate of soda solution followed by multiple water baths

To my knowledge there is no other process

I have heard of people doing it at home with drain cleaners and other sulfuric acid based compounds

It simply eats away at the once sharp corners and restores them somewhat to their original state

I have used a few over the years and they ranged from surprisingly good for a used file to downright dreadful

YMMV

I have heard of acid dips too. Tried it once at home, trying to be open minded on the subject.

This company claims to blast the underside of each tooth with abrasive under steam pressure (?). Visit the website.

Looks pretty affordable to try. I only have dull round files and depth gauge files to try, which are so cheap to buy that it is not worth it.

But for a $16 file, even getting half another life out of it could be a good deal. I’m not sure about the corners though.

Wow

That’s a whole new technique on me

I don’t have access to any of my gear or I would send a couple off just to see

When I get home, hopefully in June, if no one else has taken the plunge I’ll try them out

For science and stuffs...

Thanks for schooling me

Look pretty similar

Those look like micro chisel like the 19hx is.

I had to look up 19HX

I honestly can’t find a good enough picture to get a comparison

I have seen pictures of other Chinese chains with similar side profiles in the various threads when someone discovers a new brand of chain

Just looking at it from the side I agree it has a very linear geometric profile that might make you think it’s some weird square variant

Both of these are 19hx

So it’s harvester chain, right?

Is it considered full chisel or semi chisel or what

Looks like flat top plate, flat side plate, and a 45 degree angle jointing them instead of a 90 or a curve

 

[Wonkydonkey]

its intresting you say the chain I took pics off looks similar to an archer. the chain was from hutzl aka farmatec
iirc I ordered the same as I did before. then those guys sent me those chains, which were different to the first lot.
ive no idea which one are the correct chains to the part number I ordered.
although I'm sure one of the types was a husky chain [1.5mm] instead of the 1.6mm that I ordered.

I will go back through my orders and see if I can make anything from it.

edit. I just looked at the chain and it looks like a micro semi chisel ( its small and rounded, no sq edges), is that a rapid super in the stihl range

Yes it’s harvester they call it micro chisel.

I don’t think I have ever heard that term micro chisel before

Glad to learn something new

I didn’t mean to cause anyone to have to scramble around checking stuff out

RM in Stihl terminology I think if it's semi chisel

Manufacturers make up different terms to describe their chains. ‘Micro-chisel’, ‘chamfer-chisel’, etc. are variants of ‘semi-chisel’ chain.
