The ME31 series (Small Diameter) is a specialized variant of JD Diamond TOOLS universal PCD (polycrystalline diamond) ball-end milling cutter, specifically designed for precision machining of small features. • Compatible with the same range of materials as the standard ME31—such as non-ferrous metals (e.g., aluminum, copper), fiber-metal composites, glass, engineering ceramics and plastics, stone, and wood. • Ideal for operations where smaller diameter tools are necessary for tight spaces, intricate contours, or fine detail milling.

The ME38 Series PCD Corn End Milling Cutter (BT Holder) is designed for high-efficiency roughing operations in non-ferrous metals and composites. It features corn-style serrated cutting edges for excellent chip breaking and material removal, combined with polycrystalline diamond (PCD) cutting tips for superior wear resistance and tool life. The BT holder system provides strong clamping force and reliable tool holding, ensuring stable machining performance at both medium and high spindle speeds. This makes the ME38 (BT holder type) a cost-effective and versatile solution for industries that require both performance and precision.
