Horn broaching tools feature internal cooling

Horn has launched a broaching tool range, N117, featuring holders that allow coolant to flow through the insert seat, as well as to the side, for efficient cooling at the point of cutting. In addition, the geometries have been optimised for use in broaching machines and for turret broaching on a CNC lathe.

Targeted cooling reduces wear on the tool, increasing life and improving surface finish. Due to the internal coolant supply, a lowering of the temperature is assured even when taking deep cuts. Furthermore, the stronger flushing action improves chip removal, reducing the risk of their accumulation.

The ability to carry out broaching on a lathe offers users several advantages. In short, the process represents a cost-effective alternative to conventional broaching and can be used on virtually any turning centre. Machining can be carried out in a single clamping without having to re-fixture the workpiece. Additionally, the broaching process allows geometries of any type to be produced, from gears, keyways and helical cuts, through to curved features.
