    Dürr composite countersink DIAplus

    Countersinking is a chip-forming process that is applied to predrilled bore holes. Often deployed to create a hole that will accommodate the head of a screw, it is usually carried out in the metal-working industry because - in contrast to wood - metal doesn't yield very easily. But besides these two examples, there are of course some plastics that are just as unrelenting as metal yet much harder to machine - glass-fiber-reinforced or carbon-fiber-reinforced plastics (GFRP/CFRP), for example. These materials have met their match, however, as the new DIAplus high-performance composite countersink from precision tool specialist Dürr is said to boast a cutting force that can perfectly sink even GFRP and CFRP.

    The cutting geometry of the DIAplus constitutes another breakthrough among the precision tools that have secured Dürr great success over the years with regard to machining difficult-to-cut materials. The extremely sharp cutting edges of the DIAplus countersink slice through the stabilizing fibers of composites such as GFRP and CFRP with ease, ensuring perfectly smooth surfaces. Delamination, which would turn such costly materials into worthless scrap, does not take place. Made from a special carbide alloy and given a CCDia AeroSpeed diamond coating from the manufacturer CemeCon, the DIAplus achieves outstanding definition and offers an unrivaled service life. This solution is available in five different diameters, each with a countersink angle of 90 and 100 degrees. Dürr even caters to special requests for other angles and diameters up to 25 mm.
