  • PREMIUM HSS 4241 & TITANIUM COATED: Crafted from industrial-grade High-Speed Steel 4241 for exceptional strength, wear resistance, and heat dissipation; enhanced with a premium titanium coating for superior corrosion protection and extended tool life, outperforming standard drill bits.
  • EFFICIENT DOUBLE SPIRAL FLUTE: Features an advanced double spiral flute design that rapidly evacuates chips and debris, significantly reducing friction and heat buildup; ensures faster drilling speeds and delivers cleaner, burr-free holes in various materials.
  • PRECISE START & NO WALKING: The 118° split point tip prevents drill bit "walking" for immediate, accurate starts without a pilot hole; includes an automatic center punch to precisely mark drilling spots, ensuring professional-grade precision and saving valuable time.
