China Woodturning Carbide Cutters Manufacturer & Global Supplier

High-Speed Steel (M2, M42) rapidly loses its temper and edge sharpness when working with dense, abrasive hardwoods (such as African Blackwood, Teak, and Ipe) or silica-rich, epoxy-stabilized burls. APEX Sinter-HIP tungsten carbide cutters exhibit a room-temperature hardness exceeding 92.5 HRA and resist thermal softening well beyond 700°C. Consequently, carbide inserts sustain sharp cutting edges 10 to 25 times longer than HSS, eliminating constant sharpening breaks. When an edge eventually dulls, the operator simply loosens the central Torx retaining screw, rotates the cutter to a fresh edge, and resumes cutting immediately.

We manufacture all industry-standard profiles alongside custom OEM dimensions:
• Round Inserts: Ø8.9mm, Ø11mm, Ø12mm, Ø15mm, and Ø16mm (flat face or dished rake for hollowing vessels and rough bowl gouging).
• Square Inserts: 14x14x2.0mm, 15x15x2.5mm straight edge, as well as 2" (50mm) and 4" (100mm) radius face designs (ideal for roughing and spindle profiling without catching).
• Diamond / V-Profile Inserts: 10x28mm, 10x30mm, 35° diamond detailing cutters, and 58° detailing inserts for fine beading, parting, and dovetail tenon work.
• Bevel Angles: Typically 30° or 35° cutting relief with an 82° or 90° countersunk mounting hole compatible with standard M3/M4/M5 machine screws.

Every production batch undergoes full vertical control at our Jiangxi facilities. Starting from virgin submicron tungsten carbide powder blended in-house with precise cobalt formulations, blanks are compacted in multi-axis precision CNC presses. Sintering is conducted in advanced 100-bar low-pressure Sinter-HIP integrated furnaces. The combined vacuum sintering and high isostatic gas pressing at 1450°C closes micro-porosity (achieving ISO porosity ratings of A00 B00 C00), ensuring a dense, void-free crystal structure with exceptional Transverse Rupture Strength (TRS ≥ 2800 MPa).

Yes. As an integrated manufacturer with three specialized factories, OEM and ODM manufacturing represents over 60% of our global export operations. We can produce custom geometries from your engineering drawings or physical reference samples. Our in-house capabilities include laser engraving your brand name, part numbering, and rotation indexing marks directly onto the top face of the insert, as well as supplying customized retail boxes, vacuum blister packs, and custom-threaded Torx fasteners.

For standard catalog sizes and blanks, our MOQ starts from 1 piece (enabling fast prototype evaluation and sample testing). Standard catalog batch orders typically ship within 7 to 15 days. For custom engineered profiles requiring specialized EDM wire forming or dedicated powder compaction tooling, initial sample prototypes are completed within 14 to 20 days, followed by full volume production within 25 days.
