What are 3 flute 30 degree helix ball end mills and their uses?
We have a wide variety of 3 flute 30° helix ball nose end mills from our suppliers. The additional third flute has 50% more cutting performance than certain 2 flute applications. They are all considered general purpose end mills which have a primary and secondary facetted surface along the outside diameter. They are designed for general purpose slotting, engraving, and profiling in virtually all materials. The 30 degree helix provides good chip removal and surface finish across a wide spectrum of milling needs. They are offered in stub, standard, long, and extra long length geometries and are center cutting. They come as uncoated and AlTiN, and TiCN coated solid carbide. These are the ball end mills you need for general ball milling jobs common in all machine shops.
