928 SOLID CARBIDE DRILLS

140º point angle and precision through coolant to optimize tool life, chip evacuation, and close tolerance.

FEATURES

With a 140º point angle and precision through coolant to optimize tool life, chip evacuation, and close tolerance, the Patriot HP® 928 Solid Carbide Drill is designed to excel in all ISO class workpiece materials and in the most demanding applications.

  • Precision through coolant and 140º point angle increase chip evacuation, close tolerance, and tool life (which also increases machine utilization and process security)
  • Low thrust force design and 140º point angle suited for multi-application drilling
  • Stronger flute face for additional torque without scarifying shearing action or causing damage
  • Straight lip point reinforces the edge, perfects cutting action, and provides durability in the toughest materials
  • Advanced edge prep along drill point creates clean radius, void of fissures and high or low spots
  • Wear-resistant, low friction coating stands up against extreme temperatures, thermal shock, and difficult-to-machine materials
  • DIN 6535 HA cylindrical shank to support precision tool holding capabilities
  • Close hole tolerances with a geometry suitable for all workpiece materials
  • MQL (Minimum Quantity Lubrication) shank as standard on all sizes
  • Performs well in oil, emulsion, and dry cutting conditions
  • Wide flute design for extended tool life, reduced cutting forces, and improved chip evacuation
  • H8 to H9 achievable hole tolerance

OFFERING

DRILL LIKE A BOSS

Watch the Patriot HP 928 Solid Carbide Drill cut through stainless steel, steel and other other ISO class materials. Its low thrust force design and 140° point angle generates longer tool life and increased close tolerance hole after hole.
