We switched to Truegard SWISS #148 from Keller Heartt and it completely changed our shop. On 316 and 304 stainless steel jobs, we used to change inserts every couple of hours — now they run a full shift and still look good. We also cut cycle times nearly in half because the old oil couldn't keep up. And a bonus: it works great on brass and copper without any staining.
