Carbide Grade Selection

Grade HB-410

A Bimodal Grade Carbide

Tough, Wear-Resistant Carbide for Deep Hole Drilling Applications

Grade HB-410 is a specialized tungsten carbide engineered to deliver a combination of exceptional toughness and wear resistance. Its unique properties make it particularly well-suited for deep hole drilling applications, including gundrilling, where maintaining accuracy, straightness and minimizing tool wear are critical.

Benefits

Ideal for Deep Hole Drilling & Gundrilling

  • Specifically developed for long-reach, high-precision drilling applications.

Exceptional Toughness + Wear Resistance

  • Withstands impact and abrasion, helping to minimize tool failure and maximize uptime.

Consistent Performance in Demanding Materials

  • Reliable across a wide range of ferrous and non-ferrous materials commonly used in gundrill applications.

Engineered for Long Tool Life

  • Reduces the need for frequent tool changes in high-volume or deep-hole operations.
