Ball Nose Endmill | Precision Machining bit for Metal

Some projects need sharp corners. Others need smooth curves.

Ball nose end mills are designed for contouring, relief carving, and 3D surface finishing where a standard flat end mill would leave visible steps and sharp transitions. Whether you're machining aluminum, brass, copper, silver, or creating detailed CNC reliefs, a ball nose cutter helps produce smoother surfaces and finer detail.

These solid carbide cutters feature a standard 3.175mm (1/8") shank compatible with many desktop CNC machines, including the Carvera Air, Makera Z1, and other ER11-based systems.

Available Sizes
• 1mm Ball Nose – Fine details, small text, intricate relief work
• 2mm Ball Nose – Balanced detail and durability for general-purpose contouring
• 3.175mm Ball Nose – Larger contours, faster finishing passes, and broad surface work
