CS Unitec, based in Connecticut, US, has released the new Eco Brazing (EB) diamond grinding discs reduce sparking to 1% of that produced by resinoid wheels, making these discs suitable for use in hazardous environments such as nuclear plants, and oil and gas industries. Reduced sparking decreases the fire hazard from sparks and also increases the visibility of the workpiece, allowing more accurate grinding. The EB diamond grinding discs are suitable for grinding steel, stainless steel and other materials. Available in grits from 30 to 80 on disc sizes 4in, 4-1/2in, 5in and 7in in diameter, the disc’s light weight allows for high-rotation grinding on portable angle grinders. Additionally, its high-yield steel backing plate is elastic, helping to ensure that operators do no grind the material by over removal. The EB diamond wheel wears approximately 1% as much as a resinoid wheel, therefore increasing the tool life and significantly reducing the amount of abrasive dust emitted.
