Wholesale Solid Carbide End Mills Manufacturer & Supplier

We employ low-pressure sinter-HIP integrated furnace technology operating under an active overpressure argon cycle up to 10 MPa. This process closes residual metallurgical micro-pores (achieving ISO porosity ratings of A00, B00, C00). In addition, high-energy attritor wet milling guarantees uniform dispersion of grain growth inhibitors (VC, Cr3C2), preventing localized cobalt pooling and ensuring consistent hardness throughout the cross-section.

For ground rods, standard centerless grinding provides h6 and h5 tolerance classes, with special options holding diameter tolerances within ±0.0015 mm. For finished end mills, cutting edge diameter tolerances are controlled within 0 to -0.010 mm for general grades, and within ±0.003 mm for precision mold ball nose series. Total Indicator Runout (TIR) from shank to cutting edge is routinely verified at ≤ 0.003 mm.

Upon receiving your DXF, STEP, or detailed technical drawings, our application engineering team runs kinematic grinding simulations within 24 hours. We evaluate clearance angles, core thickness ratios, and chip flutes for your target workpiece material. Prototypes are typically ground, edge-treated, coated, and dispatched via express courier within 7 to 10 business days for customer validation testing.

Our NaNo Blue coating is a multi-component silicon-doped titanium aluminum silicon nitride (TiAlSiN) nanostructure deposited via high-ionization arc PVD. The inclusion of silicon forms an amorphous Si3N4 boundary phase that blocks oxygen diffusion, raising oxidation resistance to 1,100°C compared to ~800°C for standard TiAlN, while increasing surface microhardness to 3,600 HV for superior performance in dry, high-heat operations.

For standard catalog end mills and standard h6 ground rods, our MOQ starts at just 1 piece for evaluation samples, and 10 to 50 pieces for production wholesale batches. Stocked catalog items ship within 48 hours. Batch manufacturing for custom geometries, specific chamfering, or proprietary PVD coatings typically ranges from 12 to 20 days depending on lot size and coating specifications.

Yes. Every delivered shipment is traceable back to its specific sintered batch. On request, we provide 3.1 Mill Test Certificates containing exact chemical assays (cobalt percentage, tungsten carbide purity), measured physical properties (density, coercive force, magnetic saturation, Vickers hardness), as well as compliance declarations for RoHS, REACH, and Conflict Minerals (RMI).
