Horn’s DDHM is a CVD diamond-tipped tool system designed to provide cost-effective drilling and countersinking operations for solid carbides and sintered ceramics with a hardness of up to 3,000 HV. This drilling system further expands the company’s range of products for machining fully sintered carbides.

With new geometries for producing precise core holes, the tool system enables machining to take place on conventional milling or turning centers, thereby eliminating the need for cost-intensive and time-consuming grinding processes, the company says. Using the DDHM system also potentially helps eliminate the need for new machinery.

The company says the diamond tools enable shorter throughput times, high surface quality, lower overall costs, more 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 10 times the diameter. The CVD-0-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 have internal channels for cooling with air.

The DDHM system is especially designed for customers in the tool and die-making industries. The focus is on efficiently machining carbide punches and dies. The tool system is also said to offer advantages in other areas such as the medical, aerospace and automotive industry as well as punching, forging and forming technology.
