FEATURES

With a 140º point angle and precision through coolant to optimize tool life, chip evacuation, and close tolerance, the Patriot HP® 928 Series 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
