3/8 to 1″, 4 Flute Roughing Square End Mill Set – TiAlN Coating, Cobalt, Single End, Center Cutting | 87646667

87646667 3/8 TO 1″, 4 FLUTE ROUGHING Cobalt is harder than high speed steel and provides better wear resistance It is commonly used on high tensile alloys Square ends are used for general milling applications including slotting, profiling and plunge cutting Titanium Aluminum Nitride (TiAlN) has a higher hardness and oxidation temperature versus TiN and TiCN As a result, it is particularly advantageous for higher speed operations in a variety of steel machining applications.
