Product Overview

• Conprofe's Super-Hard Cutting Tool Series include Solid PCD micro-edge cutting tools, solid PCD thread mills, solid PCD helical milling tools, solid PCD drills, brazed PCD tools and single-crystal diamond tools (MCD/CVD/ND).
• Conprofe applies dedicated manufacturing processes and strict quality control to deliver nanoscale precision and extended tool life for high-precision industrial applications.

Advantages of PCD Tools

• Manufactured by brazing PCD composite blanks onto carbide or steel tool bodies.
• Extremely high hardness and wear resistance for prolonged life in abrasive materials.
• High thermal conductivity and low thermal expansion for fast heat dissipation, low cutting temperature and reduced thermal deformation.
• Low friction coefficient to improve surface finish and reduce machining forces.

Application Cases
Conprofe solid PCD drills excel in machining hard‑brittle materials, composites and hard‑to‑cut metals. They minimize chipping, improve surface quality and enable high‑precision ultra‑deep micro‑hole machining in sectors such as precision components, electronics and aerospace prototyping.
