"Micro PCD Drill" for Drilling Holes in Hard, Brittle Materials

Product Overview

We have achieved smaller diameters (φ0.3–1.5) for PCD drills, which are essential for high-precision machining of hard and brittle materials such as SiC and cemented carbide. With the drill tip composed entirely of PCD, these drills offer a long service life and minimize chipping during drilling. They meet the next-generation requirements for semiconductor-related components, precision mold parts, and other applications.

Application

• Small-Diameter Drilling in Brittle Materials

Product Features

Its unique tip design enables drilling with a long service life and reduced chipping.
