Four flutes produce a better finish than\nfewer flutes. The tool’s ball nose creates contoured surfaces where sharp\ncorners are not required. The center-cutting design has cutting teeth at the\nend of the tool, so it can be fed into the workpiece like a drill bit. The\n30-degree helix angle supports general-purpose applications. It balances lower\nangles’ strong cutting edge for difficult-to-machine materials with higher\nangles’ increased cutting action. Cobalt steel can be run at faster speeds and\nstays sharp longer than high-speed steel tools, while offering resistance to\nheat and abrasion. With no coating or surface treatment, this uncoated tool\ncan be used on a broad range of materials. Cutting diameter tolerance is +\n0.0010 to - 0.0000\" for end mills with a different shank and cutting diameter\nand + 0.0015 to - 0.0000\" for end mills with the same shank and cutting\ndiameter. The tool has a Weldon shank. End mills are designed to remove\nmaterial and create multi-dimensional shapes and profiles. They have cutting\nedges along the outside diameter and flutes that remove chips from the cutting\narea and allow cooling fluids to enter. If heat is not reduced effectively,\nthe tool’s cutting edges will dull and additional material buildup can occur.\nThe number of flutes can range from two to eight. Two-flute designs offer the\nmost efficient chip removal, but more flutes provide a smoother finish. The\nshank is the end of the tool held in place by a tool holder or machine.\nCenter-cutting end mills can create three-dimensional shapes and profiles, and\nmake plunge cuts similar to a drill bit. Non-center-cutting end mills are for\napplications such as peripheral milling and finishing, but cannot make plunge\ncuts. YG-1 manufactures drills, taps, end mills, and rotary tooling.
