I was using Top notch in the late eighties, they were good reliable tools, Iscar are always good but I found them as expensive as they are good so I tend to stick to Kennametal, Old habits!
I may be a dinosaur but I still like HSS for threading and grooving, I like control over my geometry in a way that indexable tools just don't allow, and when threading I like razor sharp tools which gets expensive when you need to replace tips to get that razor sharp edge for the finish cut, with HSS I take a minute before the finish cut and polish the edge with a diamond file, Lovely.
Best regards

Whatever it is, do it today, Tomorrow may not be an option and regret outlasts fatigue.
