Ringwood-based Horn Cutting Tools Ltd (www.phorn.co.uk) has launched a new broaching tool range — N117.

The holders for these tools allow coolant to flow through the insert seat as well as to the side for efficient cooling at the point of cutting; furthermore, the geometries have been optimised for use in broaching machines — and for turret broaching on a CNC lathe.

The targeted cooling reduces wear on the tool, increasing its life and improving the quality of the workpiece surface. Furthermore, the internal coolant supply ensures optimised temperatures — even when taking deep cuts.

The stronger flushing action also improves chip removal, reducing the risk of chip accumulation.

Meanwhile, the ability to carry out broaching on a lathe offers users several advantages. It is a cost-effective alternative to conventional broaching and can be used on virtually any turning centre.

Moreover, 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.
