SPI THREADED HOLE COATED ZIRCONIA FLAP DISCS

 

FEATURES:

  • Coated abrasives can be used for most applications, from grinding to polishing. They consist of a thin layer of abrasive adhered to fiber, paper, cloth or rubber. Coated discs are normally used on angle grinders.
  • Type 29 flap discs are more aggressive and the angled face provides larger surface contact for higher stock removal.
  • More durable than aluminum oxide, zirconia-alumina is best for medium- to heavy-material removal. The material grains constantly fracture to produce new sharp edges. Commonly used on carbon steels, aerospace alloys, nickel alloys, aluminum, cast iron, forgings and some stainless steels
