MACSTROC  tungsten carbide tipped (TCT) annular cutters are durable to use in hard and high tensile steel, stainless steel , rail steel as well as difficult materials, non-ferrous and alloys. It can use on core drilling machines (magnetic drilling machine) and stationary machines. Macstroc Broach cutters are built with Universal shank, Weldon shank, or *Mac-shank and it is applicable to hole cutting and process of annular groove on various magnetic drills and press. *The specifications from the Φ12mm to Φ130mm, depth of cut from 25mm, 35mm, 50mm, 75mm, 100mm *Made of high-performance CARBIDE TIPPED. And can be used on various materials, like steel plate, Copper, aluminum, cast iron, and stainless steel *Special multi-cut geometry with ply-cutting and lower friction to reach better performance of endurance and removal of chips. So its life is lengthened. It is stable made and can cut with high speed, and make the surface of materials smooth.
