Platinum

Platinum abrasives and shop equipment - Original, Razor and Razor Plus cutting discs, fiber discs, flap discs and flap wheels, twist knot wire wheels, the 9A angle grinder, PROMAX auto-darkening helmets and the FR5 flame-resistant jacket.

Fiber discs by grain

• Aluminum oxide - lowest cost, for light grinding and general purpose work.
• Zirconia - tougher grain that self-sharpens under moderate pressure. Good all-round choice for steel and stainless.
• Ceramic - fastest cut and longest life under heavy pressure. It needs pressure to fracture and expose sharp edges - used lightly, it glazes.

Cutting discs: Type 1 or Type 27

Type 1 flat discs give the deepest cut. Type 27 depressed-centre discs give clearance for flush cuts. Use aluminum cutting discs on aluminum - steel discs load up and stop cutting.

Wire wheels for weld cleaning

Twist knot wheels remove slag, scale and spatter between passes and are standard for pipe root and hot pass cleaning. Keep separate wheels for stainless so carbon steel does not contaminate it.

Match the RPM

Every disc and wheel carries a maximum RPM. It must be equal to or higher than the grinder's rated speed. The 9A grinder runs at 11,000 RPM.
