Product Overview
Rounded profile work that a square end tool simply can't produce is where the 142-3281 comes in. This 21/64" diameter 4-flute ball end mill carries a .164" radius, built for surface blending, curved pockets, and finishing work that needs a true rounded cut.
With a 30° helix and uncoated carbide body, this 142 Series tool gives dependable general-purpose cutting across mixed CNC materials. It's a practical choice for mild steel, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites wherever the feature calls for a rounded rather than flat finish.
