Tungsten carbide insert are mainly made of solid carbide and the carbide inserts are based multiple production processes. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc. Tungsten carbide is widely used as tool materials, such as turning tools, milling cutters, planers, drill bits, boring tools, etc. As the teeth of modern industry, cemented carbide tools play a fundamental role in promoting the development of the manufacturing industry. High value-added products such as precision carbide CNC tools are popular in the tungsten carbide tool market.

K Series For Cast Iron

K series carbide inserts are made of an abrasion-resistant carbide designed for turning cast iron, these kind of carbide insert tool life is longer than inserts for other materials. With a positive rake, the K series inserts can stick out in front of the holder to reach tight spaces on the workpiece. Built for semi-interrupted cutting conditions, they're commonly used to machine imperfectly round workpieces, such as shafts with a keyway. Install inserts into a matching holder.Dohrecnc offers different kinds of carbide inserts for cast iron. DZT/GHB chip breaker is suitable for ISO K medium finishing and flat form(no chip breaker ) is suitable for ISO K roughing machining.
