I'm searching for a well-priced (not cheap) possibility to buy helical-groove-engraving-cutters. This is what i'm talking about:
So i'd like to know two things:
1. What is the right term for the research?
2. Does anybody know a "cheap" shop or manufacturer?
I have no problems with chinese or indian tools, as long as they are precise and well-priced.
They have to be very sharp, uncoated and if possible, with polished groove. I want to use them for acrylic and wood-engraving.
Oh, and they should be around 1/4"
It would be very nice if someone could give me some further information and/or terms to search with
Thank you very much and best regards,
