The ME31 series is a universal PCD (polycrystalline diamond) ball-end milling cutter by JD Diamond Tools, designed to excel in machining a wide array of materials—including non-ferrous metals (aluminum, copper, and their alloys), fiber-metal composites, glass, engineering ceramics, plastics, stone, and wood. It supports multiple milling operations, such as insert milling, side milling, slotting, contouring, and spiral interpolation.

We present to our clients a wide variety of Special PCD/PCBN Tools. These tools are used for cutting cast iron, aluminum, copper, stainless, bronze, and several heat treated metals for metalworking and Automobile industries. Custom designed as per the requirements of our clients, these products are high on performance, and highly durable. Furthermore, we have designed these products to make them work with high precision machines with tolerance of 0.001mm and 0.005mm run out.

Product Details • Product Name: PCD Standard Insert – CN Type • Geometry / Shape: Rhombic (80° included angle, ISO CN style) • Clearance (Relief) Angle: 0° (negative rake insert) • Cutting Edge: Polycrystalline Diamond (PCD) tipped • Common Sizes: CN..1204, CN..1606, CN..1907 (custom sizes available) • Edge Prep: Sharp or honed depending on application • Holder Compatibility: Fits all standard ISO CN tool holders • Typical PCD Grades: 1300/1500 series or equivalent Description The PCD Standard Insert CN Type is a negative-rake 80° rhombic insert designed for heavy-duty roughing, interrupted cuts, and finishing of non-ferrous and abrasive materials. Its 0° clearance angle provides maximum edge strength, making it ideal for rigid setups and high metal-removal rates. The PCD cutting edge delivers exceptional hardness and thermal conductivity, ensuring superior surface finish and long service life in demanding applications such as automotive, aerospace, and composite machining.
