Thread: Filing Stainless Steel

  1. #1

    Filing Stainless Steel

    Hey guys,


    I need some guidance on filing stainless steel. I do not have a grinder and I get really nice results from my filing jig with my carbon steel.

    I got an order for 154CM, the first stainless steel I've worked with. The steel work hardens very easily and quickly. I know this is the case as my file will just skate across the surface. In my reading many have had the same issue.

    I've done some investigation and I see some people using Pferd Corinox files that are specifically for stainless.

    I really hope there is a repeatable and sensible solution to my problem while using a file.

    Any ideas? I know the compulsion is to suggest I get a grinder but I really enjoy working with the files believe it or not.

    I'd appreciate it!

    I have draw-filed CPM154 using a typical mill @@@@@@@ file. I was shocked at how much metal the file moved. Using a file in the usual way did not remove nearly as much metal as draw filing did. When drawing the file, play with the angles and you will discover a sweet spot that begins to bite and remove large amounts of metal.

    It's odd that you mention that but the ONLY method that works consistently is draw filing

    I have a Corinox and MaxiCut file on the way which supposedly will be harder than the work hardening and will cut through it

    I have a Pferd Corinox and love it. It will eat just about anything, as long as it is softer than the files hardness of 70 Rockwell C.

    There's always a certain level of "give-n-take" with most things we do concerning steel. The quality of files you use certainly has a huge impact on how easy or difficult the task is. I agree with John about the methodology.....draw filing is going to yield the fastest results. However.....and here's the "give" part of the equation..... draw filing is going to leave a rougher finish, which will require more finishing time. That's just the nature of the beast...... and it'll make you want a belt grinder all the more.

    so true. Typically a hand sanded finish begins for me with 320 grit. When filing, expect to begin with 120 or 220. I had forgotten about that, Ed. You brought back some fairly painful memories!

    I have a 1 x 30 but honestly I just don't have the feel for it. I mess up a lot whereas I just feel like I can go slower and be more precise with files.

    ONE DAY I'll get a nice grinder but I think there is going to be a big pay off one day because I did it the harder way first.

    In regards to the finish sanding I understand the pain there. I don't mind it as I've gotten better at it as time has gone on.

    Filing is a great skill to learn.

    If possible, find a maker in your area and see if you can borrow a couple hours on his 2x72 (hopefully with a speed control.) This will force you to sell a car or 4 rifles or a boat to get a grinder...lol. They are expensive and worth every penny. If you could experience a good grinder it would get your focus on getting one, building one, etc. It would also give you insight into the "big payoff" of "one day" having a nice grinder....which I contend would be "why did I wait so long?"

    The 1x30 is in no way a good comparison for grinding vs filing. Everybody messes up on a 1x30. I have all the tools you are using and am fairly new to making.... I simply could not resist the "compulsion" to recommend a good grinder...for good reason.

    If you have the time to file and enjoy it then don't let me get in your head. If you plan on selling knives though, it would be very difficult to break even filing them.

    I'd disagree on the 1 x 30 slightly. My new approach going to be to use the 1x30 with a jig to remove 90 percent of the stock from the bevels then finish with the files. Not as fast as a proper grinder, but faster than pure file work.
