Cemented carbide WCMT Insert end mills refer to milling cutters made of cemented carbide. To understand cemented carbide milling cutter, we need to know what cemented carbide is. Cemented carbide is a powder metallurgy product made by sintering high hardness refractory metal carbide (WC, TiC) micron powder as main component and cobalt (Co), nickel (Ni) and molybdenum (Mo) as binder in vacuum furnace or hydrogen reduction furnace. Carbide milling cutters are mainly divided into: solid carbide milling cutter, carbide straight shank milling cutter, carbide saw blade milling cutter, carbide auger milling cutter, carbide machine reamer milling cutter, carbide end milling cutter and carbide ball-end milling cutter. Use of cemented carbide milling cutter: cemented carbide milling cutter is mainly used in cnc machining center and CNC engraving machine. It can also be installed on a common milling machine to process some hard and uncomplicated heat treatment materials.

When machining, the teeth of cemented carbide end mills bear impact load repeatedly, so they Cutting Tool Inserts must have enough toughness. When cutting hardened materials, the cutting force is large, and the toughness should be improved. Nowadays, the hardness of the coating is getting higher and higher, which ensures the wear resistance of the tool when cutting hardened steel, while the machinability and toughness are more ensured by the matrix material.
The matrix material of coated cemented carbide end milling cutter is mainly K-type cemented carbide with high toughness and good vibration resistance (WC is the main component). In order to improve the toughness, the harder the coating surface is, the finer the matrix grain should be, and the higher the performance of the processed hardened steel is. The grain size of the matrix material of Impact Miracle coating can reach below 1μm, which improves its wear resistance and toughness at the same time.
