100% Virgin Tungsten Carbide Ground Round Rods D8*100mm h6 tolerence

This 8*100 carbide round bar serves as ideal raw blank for producing solid carbide end mills, drill bits, reamers, punch pins, mold core shafts and mechanical wear‑resistant parts. It maintains stable mechanical performance under continuous heavy‑load cutting and friction conditions, effectively lowering tool fracture risk and extending service life. Our factory strictly controls WC grain size and cobalt content to guarantee consistent performance among batches. Custom options including special grades, surface treatment and cutting‑to‑length service are supported for bulk orders. It is widely applied in CNC tool factories, mold workshops and mechanical processing enterprises worldwide.
