This tool excels at creating precise radii and smooth fillets in pockets and contours, thanks to its ball-nose geometry and 2-flute design that promote efficient chip evacuation. The short overall length enhances rigidity for accurate copying and reduces deflection in shallow slots, while the neck relief provides additional clearance to prevent rubbing on deeper features. The combination of 30° helix and 12° rake supports clean cutting action and good surface finish in a range of metallic workpieces.
