Tungsten Carbide Drill Bits

Engineered for extreme durability and accuracy, Retop’s tungsten carbide drill bits offer exceptional performance in metal, composite, and abrasive material drilling. Ideal for industrial and precision machining environments.

Product Description

Tungsten carbide drill bits are cutting tools made from cemented carbide, combining tungsten carbide (WC) and cobalt binders. These bits are designed for drilling through hard metals, composites, ceramics, and other challenging materials. Their exceptional hardness, thermal resistance, and edge retention outperform traditional HSS or cobalt drills, especially in high-volume or high-precision operations.

These drill bits are widely used in industries such as aerospace, automotive, mold making, construction, and oil & gas. From CNC machining of steel and titanium to rotary percussion drilling in geological exploration, tungsten carbide drill bits are the preferred solution for demanding conditions and tight tolerances.

Features

  • Submicron grain structure for enhanced toughness

  • Optional coatings: TiAlN, TiSiN, DLC for performance boost

  • Available in straight, twisted, and helical flute types

  • Suitable for both dry and wet cutting environments

  • Minimal runout for superior concentricity

  • Customized tip geometries for different substrate hardness
