Diamond Insert Cutting Tools

High Precision, Long-Lasting Cutting Solutions for Industry

  • Automotive: Ideal for cutting aluminum engine parts, composite materials, and non-ferrous components.
  • Electronics: Manufacturing of circuit boards, semiconductors, and other delicate, high-precision components.
  • General Manufacturing: Machining non-ferrous metals like copper, brass, and plastics with superior accuracy.

Advantages of Diamond Inserts

  • Unmatched Tool Longevity: Diamond’s hardness significantly reduces tool wear, allowing for longer-lasting tools compared to traditional carbide inserts.
  • High Precision and Surface Finish: Diamond inserts deliver exceptional surface finishes, reducing or eliminating the need for secondary finishing processes.
  • Increased Cutting Speeds: Higher cutting speeds mean faster production cycles, enhancing overall productivity and efficiency.
  • Reduced Downtime: Fewer tool changes and longer tool life lead to reduced machine downtime, ultimately increasing profitability.

Types of Diamond Inserts

We offer a wide variety of diamond inserts for different machining needs:

  • Polycrystalline Diamond (PCD) Inserts: Best for non-ferrous materials like aluminum, copper, and brass. Ideal for high-volume machining with a focus on wear resistance and sharpness.
  • Cubic Boron Nitride (CBN) Inserts: Perfect for machining ferrous materials like hardened steel and cast iron. CBN inserts are known for their thermal stability and hardness.

Available Insert Shapes and Specifications:

  • Rhombic (35°, 55°, 80°): Versatile shapes for various turning applications.
  • Square and Triangle Inserts: For specific high-precision and corner machining tasks.
  • Bright/Uncoated and Coated Options: Depending on your needs, choose from bright PCD or CBN inserts, as well as PVD, TiN, and TiAlN coated options for additional protection.

Why Choose Diamond Insert Cutting Tools?

Investing in diamond inserts offers long-term cost savings, enhanced tool performance, and superior machining quality. While the initial cost may be higher than conventional tools, the extended tool life, reduced wear, and fewer replacements make diamond inserts the smarter choice for high-volume and high-precision machining. Here’s why:

  • Reduced downtime from fewer tool changes.
  • High-precision machining that minimizes scrap and rework.
  • Improved surface quality, reducing post-machining processes.

Frequently Asked Questions

  • What materials can PCD inserts machine?
    PCD inserts are ideal for non-ferrous metals, including aluminum, copper, brass, and composites.

  • Can I use diamond inserts for steel machining?
    No, PCD inserts should not be used for ferrous materials. Instead, CBN inserts are recommended for steel and cast iron machining.

  • How long do diamond inserts last compared to carbide inserts?
    Diamond inserts last significantly longer than carbide, particularly when machining abrasive or hard materials.
