Import Diamond Honing Stone, Honing Stick — Buy in wholesale FOB from Supplier in China

The Diamond Honing Stone from More Super Hard Product Co. Ltd is designed for precision bore finishing in high-production environments, using synthetic diamond abrasive particles bonded to a rigid metallic or resin matrix. Available in stick and stone forms, these tools are engineered for use with Sunnen, Nagel, Belden, AccuCut, and Engis honing machines. Dimensions range from 10mm to 150mm in diameter and 50mm to 300mm in length, with grit sizes from 80 to 1200, selected based on the material being finished and the required surface finish.

The abrasive layer typically consists of electroplated or sintered diamond grains, with bond types including metal, resin, or vitrified, each suited to different workpiece materials. Metal bonds are standard for hard materials like carbide and hardened steel, while resin bonds are common for ceramics and glass due to their lower cutting aggression. The stones are manufactured to maintain concentricity within ±0.01mm and are available in standard configurations compatible with common honing heads. No certifications are claimed by the supplier, but the product follows industry-standard dimensional tolerances for honing tools.

These honing stones are used by manufacturers of hydraulic components, engine blocks, fuel injection systems, and precision aerospace parts where surface integrity and dimensional accuracy are critical. Buyers include automotive, oil and gas, and heavy machinery suppliers requiring consistent bore finishes on alloy steel, cast iron, and tool steel. Trade terms are typically FOB Zhengzhou, with minimum order quantities negotiated per batch. Packaging is in protective foam-lined cartons with individual labeling for grit and size.

More Super Hard Product Co. Ltd is based in Zhengzhou, Henan, China, and operates as a manufacturer of superabrasive honing tools. The company is verified by harbor tier standards, indicating a baseline level of trade reliability. The supplier does not claim years in business, certifications, or client lists. Its profile confirms direct production capability and alignment with major honing machine brands, but no details on workforce, revenue, or export volume are provided.

The supplier focuses exclusively on diamond and CBN honing stones for industrial bore finishing. It does not offer other abrasive products, nor does it claim in-house R&D or ISO certification. Response metrics show no recorded activity, suggesting limited communication infrastructure. Buyers should treat this as a production-focused manufacturer without documented quality systems, and verify specifications directly before placing orders.
