A variant of Horn’s successful Supermini precision tooling system has been introduced with new HP geometry, allowing higher infeed rates and other cutting parameters. It also enables multi-functional use on a lathe across a range of operations including drilling, boring, face turning and skimming.
Holes from 3 mm to 7 mm in diameter may be drilled into solid material using Supermini HP tools without a chipbreaker. While the performance data cannot compete with normal drills, the system is a practical solution if the number of cutter locations in a machine is limited. With the single-edged version, various hole diameters can be produced with a single tool.
The Supermini HP offers the option of immediately boring an inner contour after drilling without having to change the tool. An accurate 90-degree shoulder can be achieved at the base of the hole and the wiper geometry produces excellent surface quality, even at high feed rates.
