Every so often I need to cut o-ring grooves, usually on the outside of a shaft, some internal. Does anyone make a good gland tool cutting kit? Ideally it would be nice to get one of each typical size cutter. For my usage HSS would likely be sufficient as I don't do enough of them but it would be handy to have something when the need is there.

What do all of you guys use to do o-ring glands?

Is this on manual machines? On CNC it's really easy to program in whatever width you want and a corner break or radius if you want them.

Waldes Tru=Arc used to (and may still) make a nifty internal slotting tool. I have one in a leather case that looks to have been a salesman sample as it is partially cut away to show the internals. Looks like it would still work.

This is a manual lathe.

I just sharpen a piece of HSS as needed.

I bet the "Thinbit" people do...but I agree it is not hard to grind one

Standard grooving inserts is all I've ever used, and the same at other places I've worked at, too. Nothing special about cutting them unless you get a stupid over educated engineer out there that likes to over spect. groove details for holding only 250 psi!

Yes this is what I currently do then I store and label them all when do the so I know for the next time. However if you read thru the Parker handbook they show you the ideal radi that are harder to grind by hand so I was wondering If anyone sells pre cut form tools with the right profile in them preferably in a kit that had all sizes in them.

Yes, those inserts are available.
Both the plain groove and the dovetail.

I have some Nicole carbide insert grooving tool tools for external.They are way over priced.I had been grinding the internals for use in boring bars.

I found some cheap E-Bay insert tools for int.(RH & LH) & ext.Cost from $7.00 to $20.00 with inserts. They are only avail in 1mm,2mm and 3mm width but by off setting can get the widths I need.

I don't pretend to know more about o'ring grooves than Parker,but I just can't see how the corner radius is critical except for not creating a stress riser.So hand touching up the corners of the inserts is what I do.
