Sunnen’s new 60-grit red aluminum oxide honing abrasive cuts material 25 to 50% faster than other conventional stones, depending on the workpiece material. The new abrasive formulation resists chip loading and galling even in stainless steel. The 60-grit abrasive is formulated specifically for machining oil/gas industry parts where fast, base-metal removal is critical to enlarging a bore in a short cycle time. The abrasive is an ideal alternative for shops where inexperienced machine operators might damage a set of faster-cutting, but higher-cost, superabrasives or where inferior honing oils may be in use. In field tests, the red abrasive significantly outperformed brown aluminum oxide and remained clean while cutting stainless steel at high horsepower. Made with a premium, sharper grit, it provides the fastest metal removal possible for a conventional honing stone.
