Abrasive discs for grinding and cutting steel

The Silentio grinding wheel is one of new two products for freehand grinding and cutting from Tyrolit. The Silentio combines maximum stock removal rates and long life with a noise level, as perceived by the operator and others in the vicinity, said to be halved. The resinoid-bonded, fibreglass-reinforced wheel is a Tyrolit 3-star premium product, and is aimed for working on steel and stainless steel to a maximum speed of 80 m/s. It features novel damping for better run-out. Four diameters are available in the range 115 to 230 mm. Another new 3-star product for machining stainless steel at up to 80 m/s is the Super-Thin cut-off wheel. By using specially coated abrasive grain, optimising the bond system and including newly developed fibreglass reinforcement, a dense matrix has been created that promotes safety in use and long service life, despite the wheel’s 1 to 2 mm thickness, depending on diameter (115 mm to 230 mm). The wheel is free-cutting for aggressive machining and the thin profile has the effect of reducing dust, noise and machine load, leaving a clean, accurate cut with good surface finish.
