D6R3 ball nose end mill is a high-precision hard alloy ball end milling cutter widely used in mold manufacturing, surface processing, and high gloss shaping fields. This cutting tool is made of high-quality hard alloy material, combined with advanced coating technology, effectively improving wear resistance and service life. AMG introduces optimized blade geometry in tool design to maintain stable cutting performance in high hardness material processing.
Specifications
| Model | Cutting Diameter (mm) | Ball Radius (R) | Shank Diameter (mm) | Overall Length (mm) | Flute Length (mm) | Coating | Material |
| D6R3 | 6 | 3 | 6 | 50 | 12 | AlTiSiN / DLC | Carbide |
Working principle
The D6R3 ball cutter disperses cutting forces and reduces local stress concentration by contacting the workpiece surface with its spherical cutting head. The spiral design of the blade helps to achieve smooth chip removal and reduce cutting heat accumulation. Combined with a high-speed spindle and stable feed rate, the tool can achieve extremely smooth machining surfaces.
