Import Diamond Pcd Engraving Cutter — Buy in Bulk from Supplier in China

The Diamond PCD Engraving Cutter from Zhengzhou More Superhard Company is a CNC tool designed for precision engraving on hard materials including granite, marble, jade, ceramic, porcelain, aluminum, and brass. The tool features two distinct cutting geometries: a center sharp knife with a maximum engraving depth of 1mm, and a flat bottom knife capable of 4mm depth for character engraving between 3mm and 8mm. A third variant, the milling bedplate cutter, is recommended for groove milling at 2mm depth to support image base preparation.

The PCD material is imported and engineered for high abrasive resistance and sharpness retention. Typical industry standards for PCD tools include a grain size range of 5 to 20 microns and a binder content of 5% to 15% cobalt, which this product aligns with. The tool’s stability under high-speed rotation and resistance to chipping are consistent with industrial-grade PCD performance, making it suitable for continuous use on abrasive stone surfaces without frequent regrinding.

This cutter is primarily purchased by stone fabrication shops, monument manufacturers, and CNC workshop operators who require durable, high-precision tools for decorative and functional carving. Packaging is typically bulk in cartons with foam inserts, and standard trade terms include FOB Zhengzhou or EXW factory. Buyers should confirm tool holder compatibility with their CNC spindle, as no standard shank size is specified in the listing.
