All abrasive and polishing products are high quality PSA backed 3M brand. Aluminum abrasive mounting plates (discs) color coded for easy identification.
IMMF - An aluminum oxide microfinishing film that has the ability to cut hard steel. Fast cutting. An excellent choice for sharpening knives, carving tools, and turning tools. Available in finer grits than Regal or Trizact, but not as durable.
Regal - An excellent abrasive that is durable, consistent in grit, and cuts fast. Can be used wet or dry. Best for initial coarse grinding of either high carbon or high speed steel. Uses a high quality, micron graded Aluminum Oxide, bonded to a sturdy 5 mil polymeric backing.
Polishes - A mix of both Trizact and aluminum oxide polishing papers.
Trizact - A film consisting of microscopic pyramids of micron graded aluminum oxide. Wears away as it is used, continually exposing fresh abrasive, ensuring a consistent cut rate and longer life for the film. Should be kept lubricated in use.
Regalite - A ceramic and aluminum oxide blend on a strong polyester backing. The grit sizes available are in 36, 50, 80, and 120 mesh (not micron). Normally used dry, these coarse abrasives are used when moderate amounts of metal must be removed. Primarily used in sharpening planer and jointer knives, but can also be used for coarse abrading of other tools, stainless steel, or nickel alloys.
Diamond Mesh - For sharpening carbide edged blades only. Best used for initial edge grinding steps. Should be used with continuous flow of lubricant.
