Saw tail off a flat file?
 
I would like to do that. Anybody know if that's possible? And how you would go about doing it?

Thank you, as always!

I would grind a couple grooves in it, snap it off and grind broken area smooth.

A file is very hard steel and can't be sawn. You can grind it however. Frank's method will work great. A cut off wheel in an angle grinder is what I would use. The cut off wheel is only about 1/16" thick and will screw right on the threads of the grinder.

An ordinary bench grinder will also work if you hold the file at 45 degrees to the corner of the wheel. It will leave a wide groove and it will take a long time, but it will work eventually. You have to groove both sides of the tang of the file. Be careful wear gloves and eye protection. It will get too hot to hold in your bare hands. You can dip the end in a can of water to cool it off if needed. I do a lot of metal work and have grinders up to 9" in diameter. My go to grinder is a cheap Harbor Freight grinder with a 4 1/2" cutoff disc. I have several of these, and they just seem to last forever in spite of the metal dust environment. :vs_cool:

Its doable with a cut-off wheel in an angle grinder, as has already been mentioned, but i have to ask, why do you want to? The tang is there for a purpose, as a place to hold the file, im curious as to what you you have in mind where that wouldnt be needed...

I am very fond of the angle grinder.

I want to set the file onto a block at an angle to bevel guitar fret ends. The tang (now that I know what it's proper name is) would get in the way. Mine would be hardwood.https://uploads.tapatalk-cdn.com/201...3d0b0c0f62.jpg

This ^^^

I have a 4" that always has a cutoff wheel in it, and a 4-1/2" with a grinding wheel. Nothing better for cutting metal IMO. A Dremmel with one of those fragile cutoff discs would work too though it might take more than one disc.

I have a 3 in Harbor Freight air cut off tool that works for that. I also have a Dremel. Didn't think of that. :-)

i have quite a few custom metal files that were cut with an angle grinder
a 3/16" file cut in half lengthwise is a perfect keyway file for pulleys and gears

personally i find those air cutoff tools and dremels to be the worst for cutting metal
you have lots more control with a right angle grinder, all of mine are harbor fright or equivalent

Good information here! Thank you so much.
I had success adequate for what I was doing. Cut one off by clamping the file into the vice and breaking the tang off. Did not like the marring of the filing surface from that clamping so I put the tang end in the vise and had problems with braking in the right place. Actually didn't have problems with it breaking in the RIGHT place but the way I put pressure on the file to snap it caused it to break in another place. Learned something.

I'm wondering, is Harbor "Fright" frightful on purpose or simply a typo? I found it pretty darn funny! :-)

buying anything from harbor fright is a crapshoot, especially if it has batteries or a cord
though i do find myself buying more non-electrical stuff from them, i figure at my age/health, they are lifetime tools

The tail on most flat files is soft metal and can be cut with a hack saw. You can out the tail in a vise and it will bend.

I've been calling it that for years ....

See post number 3.

I don't know if the Ogre just liked the term or if he thought that he thought a new one up? :|

Home Despot, EvilBay, Harbour Fright, Amazombie, Crudeworker Supply, they all reflect some buyer's experiences.
At the same time, I have gambled on offshore tools and more often than not, hit real home runs.


NAREX (CZ) hand tools like chisels. Wonderful steel. SAMONA spokeshaves (Korea) look like Hello,
they are crudely made. But that can be fixed. The blades are razor steel, they sing in the wood.
