Thread: Tipped Tools
16/06/2009 14:14:29
Many excellent and useful response all ready and probably don't have much more to add. I too have some cheaper tipped tools that leave terrible finish I have BH600 so plenty of power and I mainly use them for roughing out. I also swear by Greenwood tools but due to expense only use for finishing cuts, they once came to give a lecture many years ago at Plymouth miniature steam it was really good and they explained the grade of carbide/cermet they use has been designed for ME on the basis that we take shallow cuts at lower speeds, they saw a niche in the market and worked with the producers of the tip to come up with something. I brought the parting tool as well and at the time had an old hobby mat lathe which I couldn't get setup to work with any parting tools. Anyway this parting tool worked a treat and I still use it now nearly 8 years on.
If you have something that works for you then stick with it, but tips are very useful and I do think greenwood IMHO was a good investment for me, even got my father in law to spend money on a set and even he was impressed and that's some going
Also on the cheaper tips, a higher speed and cutting oil gives better finish but no where as good as brazed or HSS or the Greenwood tools.
BTW I do not work for greenwood.
have fun
