'Composition: A thick alumina coated grade with a moderately hard, deformation resistant substrate. Application: This is a great finishing grade for use in a large variety of workpiece matenals including most steels, ferritic and martensitic stainless steel, and irons. The thick coating is the preferred choice for cast iron machining because it has outstanding abrasion resistance and maintains hardness at high cutting speeds. Best economy and productivity can be attained when used at high speeds. Can withstand some interruptions.
