Tungsten carbide double helix holes rod is a kind of rod with double helix holes, the general helix angle are 15°, 40°, 45°and 60°. It is composite by the main material of tungsten carbide with other additives. The main method of the rod is powder metallurgy, which owns the properties of high hardness, high T.R.S. and high wear resistance.

Tungsten carbide double helix holes rod process: powder→mix→wet milling→crush→dry→sieved→add forming agent→dried→after sieving prepared mixes→granulation→ press→forming→sintering at low pressure→forming(blank)→grinding→testing→packing→warehouse

Tungsten carbide double helix holes rod usages: widely used in production area, such as PCB micro drill,electrode rod of optical communications industry, drill bits of machining industry, drill shank, top, push rod, wear precision parts, is the best choice for CNC milling and perforated overall machining tool.

Code: ΦD×2Φd×TKΦ×LxB (L means length, B means the helix angle is 30°, and the A、C、D、E means 15° 40° 45° 60°) unit: mm
