CRX S endmills are two-flute, diamond-coated milling cutters for machining copper and copper alloys, as well as wrought or abrasive aluminium, soft graphite, CFRP/GFRP and abrasive plastics. They are available in 1–12 mm diameters with plain shanks.

The range includes square, ball nose and corner-radius cutting shapes, allowing selection for the required profile or feature. Selected styles are offered with an extended neck, while rip-processing and die-sinking variants provide further choices within the CRX S series. The cutters use DLC-coated nanograin carbide with anti-adhesion properties for the specified materials.
