Stationary cutting disc with high stock removal performance. Extra exterior reinforcement for use at high working speeds. • High cutting speed • Suitable also for cast-iron parts Machine suitability: The ST56 cutting disc can be used on stationary chop saw and table saw machines. Material suitability: The ST56 is designed especially for use on steel (carbon steel – also termed structural steel, St37, S235JR and 1.0037) and cast steels (ductile or grey cast iron, etc.). Structure and production: The cutting disc contains high-quality corundum (aluminium oxide) and 2 full-coverage glass cloth layers. The minimum side load for the cutting disc as defined by EN 12413 and oSa is 40 N (50 N from a diameter of 150 mm). The expiry date (three years) is embossed in the disc hole ring. Consistently high quality is ensured by sophisticated in-process controls applied during manufacturing. To ensure a maximum level of safety, every thousandth disc is tested destructively. This disc features a straight shape (shape 41). Cutting discs with a straight shape enable deeper insertion depths and therefore a greater number of cuts. Quality: The ST56 gives users a tool that easily meets the demanding requirements for quality in manufacturing and the skilled trades. Applications: The ST56 offers an impressively aggressive cut during use, plus smooth, vibration-free operation. This cutting disc helps to make work especially cost-effective.
