Horn Supermini HP tools

Designed for the Supermini tool system, Horn’s HP geometry is suitable for drilling, boring, face turning and skimming. The addition of this geometry is said to make the Supermini into a multi-functional tool. The new cutting geometry is said to enable higher cutting parameters, including in-feed rates. When boring, the tool provides an accurate 90-degree shoulder at the base. The trailing cutting edge (wiper geometry) produces good surface quality, even at high feed rates, the company says.

In addition to turning operations, the tool can also be used for drilling into solid material in diameters ranging from 3 to 7 mm (0.118" to 0.276"). While the Supermini HP’s performance data cannot compete with normal drills, the tool is intended to solve the problem of not having enough tool locations in the machine. The Supermini HP thus offers the option of immediately boring an inner contour after drilling, without needing to change the tool. With the single-edged version, various bore diameters can be produced using a single tool.

Horn provides tools for optimum chip control with and without a chipbreaker. For turning, the variant with a chipbreaker is recommended. The chipbreaker version is not used for drilling. The slightly twisted flute removes chips from the machining zone. The EG35 tool coating enables versatile machining of  both normal and stainless steels.

    Chip control is the bane of every shop’s existence and knowing how to consistently break chips and control burrs in ductile steels like SAE 1018, 1020, and 8620 is the holy grail of the tooling industry. When a shop experiences chip control issues, it affects their bottom line either through machine downtime, scrapped or reworked components, lost inventory due to broken tools or even employee injury.
