What should I pay attention to when choosing high hardness tungsten steel milling cutters?

Tungsten steel milling cutter is a kind of cutting tool made of tungsten steel (tungsten carbide, also called tungsten-titanium alloy).Generally mainly used in CNC machining centres, CNC engraving machines.It can also be mounted on ordinary milling machines to process some relatively hard and uncomplicated heat treatment materials, tungsten steel milling cutter is widely used, using high-speed processing.Tungsten steel milling cutter hardness for Vickers 10K, second only to diamond.Because of this, tungsten steel milling cutter has the characteristics of not easy to be worn, and brittle hard not afraid of annealing.Carbide cutting tools (especially indexable carbide cutting tools) are the leading products of CNC machining tools.

Cemented Carbide is also a commonly used material in the manufacture of general-purpose tools such as drills and face milling cutters.At the same time, reamers, end mills, machining hardened surfaces of medium and large modulus gear cutters, broaches and other complex tools using carbide is also increasing.The annual output value of cemented carbide tools and inserts has accounted for more than 30% of the total output value of cutting tools.According to the grain size distinction, Cemented Carbide can be divided into common Cemented Carbide, fine grain Cemented Carbide and ultra-fine grain Cemented Carbide.According to the main chemical composition, cemented carbide can be divided into tungsten carbide-based cemented carbide and titanium carbide-based cemented carbide.Tungsten carbide-based cemented carbide includes tungsten-cobalt (YG), tungsten-cobalt-titanium (YT) and rare carbide (YW), each with its own advantages and disadvantages, the main components of tungsten carbide (WC), titanium carbide (Tic), niobium carbide (NbC), etc., commonly used in the metal bonding phase is Co. titanium carbide-based cemented carbide is a Tic-based cemented carbide as the main component, commonly used in the metal bonding phase Mo and Ni.
