MACHINE SHOP, USA
“We ran one of the inserts on 17-4 stainless steel on our CNC lathe……..The coating did seem to make a difference. I would say at least 15 to 20% better than without it. I ran the small insert on 1045 steel. bored 40pc with 2 passes for each bore. One thing I noticed right off the bat was,the coating gave an improved finish over a standard insert finish. I did not have to change insert and finished all 40 pcs without the tool breaking down!”
