Challenger - Deep Hole Drills
  • MSTM’s Challenger Drill series is for deep hole applications for up to L/D=25 to 30. With improved tool geometry and superior coating, under ideal machining conditions, deep holes can be manufactured with single pass, eliminating pecking cycle and maximizing productivity leading to higher tool life. With superior carbide grade and specialized coating, materials up to 50 HRC can be machined.
  • Strong point geometry for stable machining
  • Customized Flute Design to ensure quick chip evacuation and edge strength
  • Slow Helix Angle with through coolant capability to improve tool stability and prevent chip jamming in flute
  • Special TiAlSiN-based coating with HiPIMS technology to minimize edge wear even at high material temperature and smooth surface finish for improved chip flow
  • Modified margin design for improved stability and tool life performance
  • Corner chamfer for added corner strength and improved entry and exit burr finish
