Polycrystalline diamond (PCD) reamers are a highly developed machining technique specifically designed for the precision machining of demanding materials such as aluminum, composites, and high-strength alloys. PCD reamers offer a long service life thanks to their extreme hardness and abrasion resistance, ensuring excellent surface quality and precise dimensional accuracy of the machined holes. These tools are particularly effective in modern manufacturing, where high production speeds and tight tolerances are required. The use of PCD reamers not only significantly reduces machining time but also minimizes tool wear, contributing to significant cost savings.
