    Ball mills are also used for the particle size reduction of black powder, cement, fertilizer, silicates and even a variety of ferrous and non-ferrous metals. Ball mills are very similar in design and operating concept to rock tumblers, which used milling media to polish rocks in a rotating cylinder.

  • Longreach End Mills Mcmastercarr

    These end mills have a long shank and a cutting edge that curves around the top of the ball end, allowing them to reach into pockets to create undercuts. Made of solid carbide, they are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup.
