Highly productive drilling

With the D1122 solid carbide drilling system, HORN presents a new generation of tools for productive and economical drilling in steel and cast materials at AMB 2024 in Stuttgart. The straight cutting edge is highly stable and reduces the formation of built-up edges. Furthermore, the corner chamfers contribute to wear protection of the cutting edge and thus to a longer tool life. The specially developed in-house HiPIMS coating offers a high level of wear protection for the tool. The open, precision-ground flutes ensure reliable chip removal.

With the new tool system, Horn demonstrates its expertise in the development of drills for demanding machining operations. The solid carbide tools offer an attractive price/performance ratio.

The customised cutting edge geometry demonstrates a high level of process reliability. Horn offers the drills with point angles of 135 degrees and 140 degrees. Two land margins ensure stability and reduced friction. The 135-degree type is available in an 8 x diameter version with four land margins. This offers optimum drilling quality and high positioning accuracy. The 140-degree drill is available in short and long versions (3 x D and 5 x D) in accordance with DIN 6537. The optimised point enables good chip formation and coolant distribution for both angles. All types are equipped with internal coolant supply. The clearly assigned material groups enable the user to select tools easily.
