  • It is recommended that only Danville 50 and 27 micron abrasives be used as they are dry, high purity alpha alumina and specially formulated for maximum performance. Other powders can result in poor performance or equipment damage, powders other than Alpha Alumina should never be used based upon health concerns. Abrasives readily absorb moisture from the air and become thickened which results in plugging. Keep abrasives tightly capped. Dry abrasive should flow like water. Moist abrasive will "avalanche" when poured or even clump. Tan color abrasives will stain white surfaces.
  • Never reuse spent powders. Both microns are ideal for all applications; 50 micron cuts slightly faster, 27 is considered by some to induce less sensitivity.
