0.6 Grain Size K30-K40 Unground Carbide Rods Dia 4mm For Metal Working

Specification:

Type: Unground Carbide rods

Diameter: 4mm +0.3

Length 330mm

Application: Endmills blank/metalworking. The high hardness and T.R.S make tungsten carbide cutting tools have excellent service life compared to other materials.

Carbide Grade: K30-K40

Hardness: HRA 2-92.5

TRS 3850-4050 N/mm²

Density 14.10-14.2 g/cm³

Grain size: 0.6μm

Our regular carbide rod diameter is from 1.0 to 32mm.

Recommend application:

Ultrafine grain size, high cobalt, good hardness and toughness, used for making endmill and reamer, especially suitable for cutting steel, aluminum alloy, and titanium.

Our advantage for inground rods:

100% virgin material, no recycled material
Spray drying tower and HIP sintering furnace
Constant excellent quality
Large stock for all sizes
100% inspected before delivery
