Drilling is one of the most important machining processes. It is where Horn demonstrates its expertise with solid carbide twist drills and specially profiled custom solutions. Drilling involves different cutting speeds at the cutting edge. While the cutting speed is highest at the circumference due to tool rotation, it is close to zero in the centre. It means that friction is at its highest here and the workpiece material is only displaced outwards. Adapted cutting edge geometries and internal coolant supply ensure process reliability and high performance.

With the D1122 solid carbide drilling system, Horn offers a new generation of tools for productive and economical drilling in steel and cast materials. The straight cutting edge ensures high stability and reduces the formation of built-up edges. Furthermore, the corner chamfers contribute to wear protection of the cutting edge and thus to longer tool life. The specially developed in-house HiPIMS coating also offers a high level of wear protection for the tool. The open, precision-ground flutes ensure reliable chip evacuation. With this tool system, Horn demonstrates its expertise in the development of drilling tools for demanding machining tasks. The solid carbide tools offer an attractive price/performance ratio.

Drilling with profiled tools enables economic advantages in series production. Based on the 117 tool system, Horn offers profiled inserts of 16 mm diameter and above according to customer requirements for use on turning and milling centres. The patented, high-precision insert seat of the 117 system guarantees high concentricity and axial runout accuracy, as well as repeatability of placement to within microns. The precision-ground cutting edges deliver high accuracy and surface quality. The cost savings are derived from the possibility of retipping, lower tool costs and less machine downtime. Cooling of the contact zone and removal of the chips are ensured by internal coolant supply through the round shank to both cutting edges.
