Ball end mills, also known as “ball nose” end mills or full-radius end mills, have a constant single radius – or ball – at the end of the cutting tool. The nose radius is equal to half the diameter of the tool, and the edges are center cutting. The cutting profile has no sharp corners or straight edges.

HTPM series milling cutters have unequal flute spacing (variable pitch) and multiple helix angles (35° and 37°) to reduce chatter and harmonics, for improved stability and better finishing. This also optimizes chip formation and chip evacuation. These 4-flute end mills feature a spherical ball end.

Aluminum Chromium Nitride (Hybrid AlCrN) coating reduces wear and increases heat resistance. These end mills are excellent for roughing and finishing, and fully capable of taking heavy cuts in steel, stainless steel, titanium/Inconel up to 40 HRc, as well as cast iron.

HSAM1 series milling cutters are 2-flute, center-cutting, high-performance end mills for aluminum. They have unequal flute spacing (variable pitch) to break up harmonics and reduce chatter and vibration. The wiper facet design improves floor finishes. These end mills provide extraordinary metal removal rates (MRR), by combining roughing and finishing operations for any aluminum plunging, slotting, and profiling application. The proprietary flute geometry is designed for rigidity and improved chip evacuation, generating wall-to-floor perpendicularity, even in thin-wall applications.

Ball end mills are used for a variety of milling operations, such as contouring, profiling, slotting, and pocketing. Due to their shape, they are particularly suited to machining 3D part contours, milling large corner radii, and grooving with a full radius. Ball end mills are commonly used for finishing and semi-finishing operations in moldmaking, tool & die, and other applications with complex contours and profiles.
