Grade Data - Brake Drum & Rotor Turning

Uncoated Grades

Uncoated carbide grades are composed of tungsten carbide and a cobalt binder, with some grades having an addition of titanium carbide and/or tantalum carbide, to enhance critical properties. Uncoated grades are very versatile and can be used in almost any metalcutting application for cutting iron, steel, stainless steel, high-temperature alloys, non-ferrous metals, and even non-metallic materials such as plastics and composites. These grades are best-suited to applications with lower cutting speeds or for short jobs.

AN2 K10-K25
C2 AN2 is an uncoated, unalloyed grade with good abrasive wear resistance. Designed specifically for turning of cast iron and other non-ferrous materials, this is the perfect general purpose grade for brake drum and rotor turning.


CVD Coated Grades

CVD coated grades start with solid substrates, many with cobalt-enriched surfaces to promote coating adhesion and enhance cutting characteristics. Coatings are applied through chemical vapor deposition (CVD) in specialized furnaces. Materials such as titanium carbide, titanium nitride, titanium carbonitride, and aluminum oxide are applied in various thicknesses and combinations to create a variety of grades tailored to specific metalworking applications. These grades offer cobalt-enriched substrates which produce cutting edges with increased edge strength and fracture resistance. CVD coated grades can be used for machining cast irons, steels, stainless steels, and exotic materials.
