High-performance solid carbide ball nose cutter for NF-metals
The 2-flute solid carbide ball nose cutter provides tool and die makers with a sophisticated solution for 3D contour milling and copy milling in soft materials. The combination of a polished, uncoated K30 solid carbide substrate (RT30K) and a 30° helix angle promotes rapid chip evacuation while minimizing the built-up edge formation typical when machining aluminum. Thanks to its hemispherical tip and centre-cutting geometry, this tool opens up flexible application options, whether for plunging, profile milling or machining clean full radii.

Applications
This solid carbide ball nose cutter is aimed at professional use in 3D contour machining, pattern and mold making, as well as milling transition radii. The design is explicitly suitable for shoulder milling, slot milling, form milling, and ramping in long-chipping non-ferrous metals. The large chip space of the 2-flute construction makes a decisive contribution to ensuring that the resulting aluminum chips are transported away from the cutting zone without jamming.

Special features
Thanks to its uncoated condition, the applied K30 substrate offers extremely sharp and smooth cutting edges, significantly reducing the risk of material adhesion. Combined with the centre-cutting geometry, the ball nose cutter supports efficient workflows, as alternating cutting depths and steep contours can be handled reliably. The precise rounding of the cutter head forms the foundation for a consistently high surface quality on the workpiece.
