Paul Horn GmbH is proud to present DDHM, its CVD diamond-tipped tool system for cost-effective drilling and countersinking of carbides and sintered ceramics with a hardness of up to 3,000 HV. With the launch of this drilling system, Horn is further expanding its range of products for machining fully sintered carbides. With new geometries for producing precise core holes, the tool system allows machining to take place on conventional milling or turning centres and there are no costly and time-consuming grinding and eroding processes. There is also an opportunity for savings in that investment in expensive new machinery can potentially be avoided.

The DDHM system is aimed primarily at customers in the tool and die-making industries. The focus is on machining carbide punches and dies efficiently. However, the tool system also offers significant advantages in other contexts, including the medical and aerospace sectors; the automotive industry; and punching, forging and forming technology. The diamond tools enable shorter throughput times, high surface quality, lower overall costs, greater flexibility within the production process and longer tool life. The drills can be used for producing holes in solid material to a maximum depth of ten times the diameter. The CVD-D-tipped drills have a two-edged design and are available in diameters ranging from 2 mm (0.079") to 10 mm (0.394"). All versions boast internal channels for cooling with air.
