Grit Size Conversion Chart

Steel abrasives are often measured in grit size indicating the number of particles in a specific area, whereas mesh sizes measure the particle size passing a woven wire screen. Non-steel abrasives larger than 40 grit also use the direct pressure delivery blasting cabinets to pneumatically push the larger and heavier abrasives. Media Blast & Abrasive recommends the PowerPeen for these larger sizes.
