HSS rotary cutters Product information Cut 1 Cut 2 Cut 3 Cut 5 Cut ALU without chip breaker with chip breaker with chip breaker without chip breaker HSS rotary cutters are, due to their special Cut 1 Cut 5 tooth geometry and high production quality, Ideally suited for cutting steel, cast steel and Ideally suited for finish machining, for example particularly suitable for deburring, chamfering, stainless steel (INOX). deburring of steel, cast steel and cast iron. fettling of castings and for the machining of aluminium. They can also be used economically Cut 2 Cut ALU with low-performance machines at lower speeds. Ideally suited for cutting steel, cast steel and Ideally suited for cutting soft non-ferrous metals, cast iron. Also suitable for fine machining, for brass, copper, aluminium alloys, plastics, Advantages example, deburring of steel, cast steel and cast fibrereinforced plastics and rubber. ■■High aggressiveness. iron, non-ferrous metals and plastics. ■■Can be used at low speeds. ■■Large chip removal per time unit. Cut 3 ■■The viscosity of the high-performance high- Ideally suited for cutting steel, cast steel and speed steel (HSS) results in a great stability of cast iron. Also suitable for fine machining, for the tooth cutting edge. example, deburring of steel, cast steel and cast iron.
