Today we are testing samples sent by our overseas customer, the 125 series, to check its cutting performance on stainless steel and steel bars. 125 cutting disc test: cut two different materials separately and check the wear loss after testing. First sample: 16mm stainless steel round bar. Start cutting. After 69 cuts on stainless steel, residual weight: 15g, residual diameter: 82mm. Second sample: 16mm round steel. After 56 cuts, residual diameter: 79mm, residual weight: 13.6g.
