With Pferd 411 ne grinding oil, you achieve clean, stain-free finishes on stainless steel and non-ferrous metals like copper, brass, and bronze. The specialized formula provides active cooling and lubrication during grinding, preventing metal chips from sticking to your coated abrasives. This stops unwanted discolouration and marks on sensitive stainless steel surfaces before they can start. By significantly reducing friction and heat build-up, you extend the service life of your abrasive belts and discs while securing a consistent, uniform finish. The convenient 400 ml aerosol spray can allows fast, targeted application directly to your workpiece in any metalworking job.
