  • Constructed of M-35 High Speed Steel
  • Contains five percent cobalt steel for super abrasive resistance in tough metals
  • Heavy-duty web construction for strength and durability
  • Heavy-duty spiral flute design produces faster chip ejection
  • Shorter cutting lips reduce torque for drilling in high tensile strength materials
  • 135° split point allows drilling to start on contact, minimising bit ‘walk’ and reduces feed pressure for easier penetration.
