Import Diamond Honing Tools — Buy in wholesale FOB from Supplier in China

Moresuperhard supplies single-pass diamond honing tools designed for precision bore finishing in industrial components. Each tool consists of a superabrasive diamond sleeve mounted on a tapered mandrel, engineered for one-stroke honing cycles. The tools are available in electroplated and sintered configurations, with diameters customised to match workpiece drawings. Machinable hole diameters are not standardised but tailored to client specifications, typically ranging from 2 mm to 50 mm depending on application. The design allows compatibility with most standard honing machines without requiring tool modification.

Electroplated diamond tools use a nickel bond to secure diamond grit, offering consistent cutting performance across mild steel, hardened steel, cast iron, and ceramics. Sintered versions provide longer life under high-load conditions and are preferred for abrasive materials like carbide and glass. The abrasive sleeve design includes engineered chip channels for efficient debris removal, reducing thermal buildup and improving surface finish. Typical diamond grit sizes range from 80 to 400 mesh, with finer grades used for finishing and coarser for stock removal. Surface roughness targets can reach Ra 0.1 µm or lower when paired with proper machine parameters.

These tools are widely used in automotive, aerospace, and refrigeration manufacturing for honing cylinder bores, hydraulic valve seats, brake cylinders, and powder metallurgy components. Buyers include engine part manufacturers, compressor producers, and precision machining shops requiring tight tolerances. Orders are accepted for both standard models and fully custom designs based on technical drawings. Packaging is protective foam-lined steel cases, with lead times of 15 to 30 days for custom orders. MOQ is typically one unit for prototypes and 10 units for production runs, subject to confirmation with the supplier.
