Ground h6 solid carbide fixed-length drills blank HRA 94.0 with
Nano grain size
Specification: OD Ø1.6mm, length 26mm.
Type: h5 ground solid carbide cut to length rods.
Application: Nano grain size, with high wear resistance and
toughness, suitable for finishing of hardened steel,
high-precision, and high-mirror processing of graphite. Good for
making drills.
Recommend carbide grades for machining Aluminum:
Cobalt: 9%
Hardness: HRA 94.0
TRS 4200
Density: 14.45
Grain size: Nano grain size
Advantages of our tungsten carbide rods:
1. Extruded rod and HIP sintering.
2. Ultrafine particle size powder.
3. Runout and roundness can be less than 5 microns (0.005mm).
4. Carbide rods are solid or with straight/spiral coolant holes.
