Can't you move the cutter laterally and make the groove as wide as you want it? Unless the insert is wider than the groove you want of course.

These are fairly big Willie, would have to look but think they're 1/8 and 3/16 inserts. The last ones I needed were .030.

Ah yes. Gottcha Greg. That's exactly why I asked about the thin grooving tools. I have a couple of parting tools that I always wished they were thinner. It sounds like the Nikcole set that Ed and Russ have pretty much fills the bill in that area. And I just discovered that they have threading inserts for them as well. At that point resistance was futile and I placed the order.
I really should change my grinder back to normal someday.

Follow-up question:
I finally got the Nikcole set after the US postal slow system delivered it to the wrong address for the umpteenth time. (How do you go about getting an inept mail carrier reassigned to a different route???)
Anyway... I was just looking online at the 'GP' grooving and cut-off inserts. I don't see any information about what the maximum diameter is for these cut-off inserts. They don't look any longer than the standard grooving inserts.
Looks like the timing was right for me though. Victor's site shows "Last chance at the old price". ($116)

Hi Willie,
According to http://www.mscdirect.com/browse/Indexable-Cutting-Tools/Indexable-Inserts/Cut-Off-Inserts?navid=12107160+4287902322
Max depth of cut is 6mm (0.2362")

RE: Thin grooving tools? - Highpower - 02-14-2014
Hmmm... interesting. Nikcole's site shows the length of the top edge as 0.235" but because of the angle in the center of the body of the insert, it looks like max depth of cut would be half that.
And both types of inserts appear to have the same length. So I'm still left wondering what the difference is between grooving and cut-off?

Nikcole's web site sucks. There really is very little information about their products on it and what is there is so small you can't read it.

Sounds like a question for Ken.
I wonder if there is a radius on the edges of the groove inserts, so that you don't introduce a stress point by having a square edge. That wouldn't be necessary on the parting inserts. Also, you can get negative/positive parting tips, so that you leave the pip on the stock and not the part.
I'm probably totally wrong though!

What's the use of a parting off tool that can only part off from less than ½" dia. stock?
