Wholesale Inserts & Tools For Carbon Steel Processing Manufacturers & Factory

Standard vacuum sintering leaves microscopic internal voids and residual porosity within the WC-Co matrix. APEX utilizes integrated low-pressure Sinter-HIP furnaces operating at 60 bar with pure Argon gas during the liquid binder phase. This pressure profile collapses internal pores, increases transverse rupture strength (TRS) by 15–20%, and prevents catastrophic tool fracture during heavy interrupted cuts on carbon steel weldments or raw forgings.

For unhardened AISI 1045 carbon steel (approx. 180–220 HBW), recommended surface cutting speeds (Vc) range between 180 and 260 m/min for semi-finishing operations with an edge hone of 25 µm. Under heavy roughing conditions, Vc should be maintained at 130–170 m/min with chip loads (fz) of 0.12–0.28 mm per tooth, ensuring sufficient feed volume to push heat away into the chip body rather than into the tool core.

Yes. We run dedicated production cells across our 3 factories. We supply unground sintered rod blanks (330 mm standard length), centerless ground solid and coolant-channel rods with h5/h6 diametrical precision, as well as finish-ground indexable inserts and special custom tooling according to CAD drawings (.step/.dwg formats).

Tool edge preparation is processed through multi-axis CNC brushing and micro-abrasive blasting systems. Every mass production run is monitored using 3D optical surface profilers (focus variation metrology) to guarantee that the hone radius (K-factor and Eradius) falls within a controlled band of ±3 µm, preventing premature micro-chipping or early built-up edge formation.

Standard in-stock rods and blanks ship within 48 to 72 hours. Custom formulated preforms, drawing-based special tooling, or custom coated inserts follow an initial sample verification process (typically 7–10 days). Mass batches ship between 15 and 25 days depending on total quantity, backed by sea/air shipping options and export documentation.

Our minimum order quantity for standard ground or unground carbide rods begins at 1 piece to allow for sample validation on your CNC tool grinders. For custom-profiled inserts, step drills, or drawing-specific tool blanks, the typical MOQ is 10 to 50 pieces depending on geometry complexity and tooling setup requirements.
