3/16" cutting diameter, 2 flutes, double end, ball nose, uncoated.
Ground from solid carbide. This tool cuts 3/16" diameter, has 1/2" of flute and measures 3-1/4" overall.
The ball nose leaves a radiused bottom, which is what you want for 3D contours, fillets and mould surfaces rather than flat floors.
The Weldon flats give the holder a positive grip so the tool cannot pull out under load.
Uncoated, so the edge stays as sharp as it can be ground — the usual choice for aluminium and other soft, sticky materials.
