Magnum 1/2" (12.7 mm) Ballnose HSS End Mill (EMB12)

Machining complex 3D contours and smooth radiused internal pockets is effortless with a precision-ground tip. The Magnum EMB12 Ballnose End Mill is essential for mold making, decorative surfacing, and die work where standard square ends cannot reach. This High-Speed Steel tool features a hemispherical tip for smooth transitions between depths, providing the structural mass needed for stable surfacing passes in steels and non-ferrous alloys.

Frequently Asked Questions

Q: What is the main use for a ballnose end mill? A: They are used to create curved surfaces, fillets, and 3D contours that a standard flat-bottom end mill cannot produce.

Q: Can I use this for slotting? A: Yes, but the slot will have a full radius bottom; for flat-bottom slots, use a square end mill.
