E-Clip Grooving Tool

[bretthl]

Grooving? Anyway ... anyone know of lathe tooling specifically for cutting E-Clip grooves? I currently use a tool made from O1 but it is not great, I have to cut at 30 rpm.

For some of the larger ones I use my standard parting tool, which is 0.040 wide and for narrower ones I have ground down a HSS tool blank similar to a parting tool.

I need a 0.050" wide groove.

Use a retaining ring grooving tool like this one: https://www.amazon.com/Micro-100-RR...100+retaining+ring+grooving+0.050"+right+hand

This one has a groove width of 0.030". Allows you to sneak up on the fit.

Is that an internal tool? I need external (E-Clip)

My mistake. Yes, that is an internal grooving tool. For external grooving, a simple HSS parting tool works fine. A P1-N blade is 0.040" wide and should work well.

Sneak up on it like Mike mentions. Or if you are doing many then grind one.

Easy enough to grind one to suit.

Ditto; grind one from a tool bit.

The clip is 0.042". Do you know of a wider cutoff insert? That would be ideal. I have only an HSS cut off.

This is what I have been using but it is slow (O1 Q&T 0.050" thick). Stays sharp. Does not cut well. Have to turn it at 30 rpm with oil. Is the shape wrong?



I have 60 of these to make (+ additional machining) and I have made only 20 shown below. T416 1/2" round.
