Sorry, didn't get that across very well. They're a great system of someone like yourself Russ who is cutting dozens of groves over and over and therefore can stock a good range of inserts. I might need one grove with an odd width, I can't afford $16.90 for the insert that may never get used again, (and I'd probably never find it if I did need it again)
Free advice is worth exactly what you payed for it.

I'm with Greg on these inserts as well as carbide inserts in general. They are ideal for running a larger number of parts, but not economical or practical for the home machinist. In addition, they are easily damaged by a less experienced operator. High speed steel is more versatile, economical and forgiving than carbide in the home shop. That said, I do use carbide. I have a selection of carbide end mills, a carbide face mill for my mill and a set of insert turning tools for the lathe that I use for roughing. The turning tools are not very useful with Hardinge because it lacks the power required to use them effectively, all it takes is one stall and the insert is toast.

Good points from both perspectives.

I agree Willie. Tough decision but I went ahead and ordered the kit. I hate grinding tools, probably because I suck at it.

Ed,
You won't regret your decision buying that kit. Keep the tool loaded in a holder on center and leave it that way. Whenever you need a groove, pop in your insert and go to town.
Simple rule of thumb for grooving. If you do not have an insert that is full width (from the ones supplied with the kit), use one small enough to step over half the width of the insert.
Ex: .050" wide groove - use a .035" wide and step over .015" to finish.
You should NOT use the .043" wide (in the kit) and step over .007".
Always try to step over at least half the width of the insert and it will keep the side walls straight.
Best Regards,
Russ
