| The TOL. of Unground cut-to-length rods | ||
| D / L (mm) | The TOL. of D & L in mm | |
| L <= 70 | 70 < L <= 150 | |
| D < 5 | D (0.20 ~ 0.30), L (0.20 ~ 1.5) | D (0.25 ~ 0.35), L (0.20 ~ 1.5) |
| 5 <= D < 40 | D (0.25 ~ 0.35), L (0.20 ~ 1.5) | D (0.30 ~ 0.40), L (0.20 ~ 1.5) |
The tolerance of the long rods is h5/h6 or at customer’s requirement in Dia., and 0.00~+5.00mm in Length as normal.
The tolerance of the ground cut-to-length rods is h5/h6 or at customer’s requirement in Dia., and 0.00~+2.00mm in Length as normal.

Frequently Asked Questions (FAQ)
Tungsten solid carbide rods are press molded through extrusion or die pressing, and sintered using a low-pressure sintering integrated furnace to ensure high overall physical performance and structural density.
The outer diameter can be precision-ground and polished according to customer requirements. Common standard tolerances include h5, h6, and -0.005mm, with optional end chamfer processing.
They are suitable for cutting and machining general steel, cast iron, stainless steel, heat-resistant steel, nickel-based alloys, and titanium alloys.
They are primarily utilized as blanks for general-purpose carbide cutting tools including twist drills, end mills, machine taps, and gun drills, as well as specialized PCB micro-drills.
The main variations include unground long rods, unground cut-to-length rods, precision ground long rods, precision ground cut-to-length rods, and PCB rods.
APEX Carbide maintains high quality standards through proprietary blank production, rigorous inspection and testing processes, advanced CNC grinding equipment, and professional packaging and shipping.
