This is a set of single flute end mills cutting tool used in industrial milling applications. It is distinguished from the drill bit in its application, geometry, and manufacture. Single flute end mills are used for superior chip evacuation in high speed milling. These end mills are made of tungsten carbide which will tolerate a lot more heat while still keep a good hardness. Features: This set of end mills are made from high quality tungsten carbide for good hardness and the cutting edge is quite sharp. 1/8inch cutting edge and 1/8inch standard shank diameter would fit for many milling machines or CNC cutting machines. Single flute designed end mill with sharp cutting edge would offer a smooth cutting surface and chip clearing. There are total 5 pieces end mills in this set that would be great replacement. Usually these end mills are used for cutting acrylic, PVC, MDF, density board, wood and many other soft materials.
