diprofil-polishing-stonesEDM-series

Our most popular series containing hard Aluminium Oxide. A hard-structured stone, especially developed for the removal of the hard “scale” left by the Electrical Discharge Machining process. Read more about our dimensions and grit sizes for EDM-series (opens as PDF-document).

FAO-series

Soft Aluminium Oxide. A very accurately graded aluminium oxide stone. Soft bonded with rapid breakdown for final finish work. Read more about our dimensions and grit sizes for FAO-series (opens as PDF-document).

HCM-series

Resilient resin bonded stone. Extremely snap resistant. Does not scratch or load. The resin helps to produce a silky finish. Read more about our dimensions and grit sizes for HCM-series (opens as PDF-document).

MOL-series

Semi-hard Aluminium Oxide which is widely used for removal of EDM surfaces and for finishing heat-treated moulds and dies. Especially good for slots and ribs. The stones are oil-filled to prevent loading. They break down slowly and retains shape. Read more about our dimensions and grit sizes for MOL-series (opens as PDF-document).

SCM-series

Semi-hard Aluminium Oxide. Excellent for all mould and die surface finishing. Fast cutting and breaks down slower than the SSC-series. Good for fine EDM surfaces. Read more about our dimensions and grit sizes for SCM-series (opens as PDF-document).

SSC-series

Medium-soft Silicon Carbide for general mould and die polishing. Breaks down evenly and retains shape. Will not load. Very fast cutting. Recommended for heat-treated surfaces. Also good for milled and turned surfaces. Read more about our dimensions and grit sizes for SSC-series (opens as PDF-document).
