1. Product Overview
The Kyocera SC Rod DIA7 L310.0mm KPTZ0022 is a Kyocera solid carbide rod blank, Ø7 mm × 310.0 mm, manufactured from ultra-fine grain (0.4–0.6 µm) tungsten carbide for grinding custom cutting tools — endmills, drills, reamers, punches and wear parts. The h6 ground diameter with ≤ 0.02 mm/100 mm straightness allows direct tool grinding without pre-machining.
This blank weighs approximately 172 g (ρ = 14.4 g/cm³) and provides enough stock to grind tools up to Ø7 mm with 310 mm of usable length. Its ≈ 4,000 MPa transverse rupture strength and HRA 92.0–92.8 hardness give the finished tool both sharp-edge capability and chipping resistance; grind with diamond wheels (D64–D126 roughing, D15–D25 finishing) under continuous coolant.
