Hi Vic,
Sorry but I have no experience of Glanze brand, but I have a little of other types. I would ask if this is your first insert parting tool? If it is, you might find the technique different to your past methods. Another question would be, which lathe do you have?
Now for a little general advice, first off, do not think just because you can have lots of overhang that you can use it all. Limit yourself to, say, 1/2-3/4" projection, any more than that and things may start to get bent. The next thing is to be more aggressive in parting than you would with HSS and if it starts to squeak use some more fluid. How aggressive is down to experience and good judgement and, of course, lathe construction.
I suppose I should have started by asking in what way did it behave that caused you to be not impressed? What were you expecting and how did it fail to achieve those expectations?
