Cutting hardened steelwith angle grinder

Brown fused alumina is widely used as a raw material in refractories, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding and hundreds of other applications. Washington Mills' brown fused alumina grains and powders are available in standard grit and powder sizes and they can also be made to individual specifications.

¹ = When we say “abrasive blade”, we don’t mean “abrasive grinding wheel”. Never cut with an abrasive grinding wheel. It will shatter or explode on you if you do.

This video, in addition to showing you how to cut hardened steel with an angle grinder, has some valuable safety tips. These tips include how to cut with an abrasive blade¹ without having the blade shatter or break on you. Of course, you don’t have to worry about your blade shattering, breaking or grenading if you cut with a Safety Blade or Safety Blade Grinder/Cutter, because they’re made of solid steel (up to 14″) to prevent such accidents.
