Specifications

  • Manufactured from high-speed steel with 5% cobalt content (HSS-E5) for enhanced heat resistance and cutting stability
  • Features a TR-type self-centering tip (135° point angle) to ensure precise starts and minimize walking
  • NTA type flute geometry with high chip clearance for optimal debris removal
  • Short series (DIN 338 standard) for improved rigidity
  • Four-facet sharpening derived from monobloc carbide techniques for sharp, durable cutting edges

Usage

This drill bit is designed for use with rotary drilling machines. It excels in drilling through stainless steel and cast iron, benefiting from advanced flute geometry and cobalt alloying.
