These rather nice chaps will send you a rather neat Speed n Feed thingy (like a slide rule) which details RPM, SFM, No Inserts, IPM, FPT, DOC Horsepower, MMR n stuff.

Just E-Mail them, or you can use their online calc. Click on "Free Stuff" up the top of their Web page.

I got no connection with the company other than the fact that they sent me a freebie, which I thought was jolly nice of them
