Deburring Stones (stones for deburring)

Don't laugh! I realise this might not be a *thing*, but ...

I am already in the possession of a bench lay whetstone to sharpen some of my tools. However, I've seen a few videos of late where a few of the popular hobbyists use (hand) stoning to finish the edges of their work.

Are these just the usual Aluminium Oxide/Silicon Carbide stones or something a little more specialist?

I did watch a video [0] in an attempt to educate myself, but it turns out the range/choice is even wider than I first thought.

The only time I hand stone (so far) is touching up HSS tooling but you're right that available stones are numerous - even akansas stones are in different grades. If you start looking at japanese knife sharpening (water) stones then the grit range is also massive. For practical reality just 'touching' up a HSS tool a small fine stone is all that's needed. The one I like best was a wesh slate stone but by it's nature it didn't last as long as the more dense types and i haven't managed to replace it. Some folk prefer a small fine diamond on plastic thingy instead 'cos all I'm doing is essentially a quick honing.

(when I'm using the term hand stoning I'm talking about holding stone and HSS in each hand for a few strokes as opposed to shaping or sharpening a wood chisel and honing the edge of that)

You can use any abrasive material to remove burrs, etc. Whetstones are handy - rectangular for flat or outside radii, round versions (also called slips) can be helpful for internal curves. And so can files, the finer the better, as long as the component is not dead-hard.

Abrasive papers (emery, wet & dry, etc) can also be used, and there are neat tools a bit like a bent screwdriver which can be run along a burred edge and clean it up without leaving traces of abrasive around.

Another way, used in industry a lot, is to put burred parts in a sort of concrete-mixer device, along with pebbles, or steel balls, (etc) and a liquid, and roll them round for an hour or two.

Hope this helps

I like a fine India oilstone for touching up tooling. For deburring I generally use a fine flat Swiss file, or a 6" second-cut flat for larger work.

The diamond lap I use for keeping router bits sharp is handy for taking sharp edges off and a very light treatment of a cheap digital caliper was transformed to a smooth action pleasant to handle tool, I suppose it was almost a polish.

I have a small 1 inch by 1/2 inch by 4 inch smooth one side rough the other side India  stone and it fixes most burrs or bumps. Or a needle file fir soft material.

on the subject or deBurring.......

I use a chainsaw flat file for that job around the lathe.....have the other shapes as well.......

also have 1 perm on both mills........they are that cheap......

Oregon and other's make em.....€4 each the last time I bought some.....

Mine are European made but just cant rememeber the name and anyway the are buried in a packing crate somewhere.....

My thinkig was when I bought my first file was that if the can sharpen a HSS steel blade, it will do all I want.....

My go to little flat ultra fine file, always on the lathe must be now 10 years old and still works like new......

always coved in an oily residue (Suds), just a wipe off with a dry cloth and off u go again.....

Sometimes I even tickle a shaft that needs a tiny amount taking off or polishing.....u know when the bearing is just to tight.....

Have given a few to friends when visiting and all remark how good they are.....

Remember now "Bacho" .... Sweden not Europe.......sorry a grey moment.....hahaha...

Bahco files? Portugese
Argument re Sweden ..can be classified as Northern Europe (optionally Scandinavia) and Sweden is in the European Union (1995)

..need more grecian 2000

Thanks guys that's super helpful.

@John Pace, I watched that too, but it's not relevant unfortunately.

The Oregon files I have were made by Valorbe.

Be that as it may, I use a file or a deburring tool for deburring edges in the lathe or after grinding/milling and either a dubbed (surface ground to be flatter) handle-less file or a ground flat Norton type stone or a hard flat Arkansas stone for deburring flats, depending on the level of precision needed.

Tongue in cheek Lee, yes I do have a few sharp edges

A while ago, I bought a so-called oil stone from the local superstore without there being any indication of its quality. I was expecting a typical double-sided oil stone for sharpening wood chisels etc.

When I came to use it however, I found it was softer than the donkey stones my mother did the steps with; actually the latter is not quite true.

One of the stones I value in my toolbox is Arkansas.

A bit brittle but gives a good final finish.
