Vortex Carbide Burr Type C - Ball Nose Cylinder - Double Cut - 16mm Diameter SPIRALMILLINSERT 7 is a precision inspection

7 is a precision inspection tool designed to verify external thread diameters on metric coarse threads

30° helix with facet relief for smoother cuts: The 30-degree helix and facet relief minimize rubbing and chatter

Color/finish: Light Grey with Dark Grey drawer fronts for a professional

Long flute length for rigidity: The 8–12xD flute length increases rigidity and reduces deflection during deep drilling

and other substrates without coatings that can affect heat management or finish

Vortex Carbide Burr Type C - Ball Nose Cylinder - Double Cut - 16mm Diameter SPIRALMILLINSERT 7 is a precision inspectionThe Vortex Carbide Burr Type C Ball Nose Cylinder Double Cut is a rugged carbide rotary burr engineered for precision metal shaping, deburring, and finishing. With a 16 mm diameter and a ball nose profile, it glides over curved surfaces and tight edges, delivering consistent detail work across a wide range of metals. Ball Nose tip for curved surfaces: The rounded end follows complex curves and edges smoothly, enabling gentle transitions on radii,
