ME31 series PCD end milling cutter (Small diameter)
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.
