Features

  • Engineered for heavy duty work, BLITZ BITS® are high performance drills for production as well as tough maintenance applications
  • Made from a premium grade of M-7 molybdenum high speed steel, which has a special black and gold surface treatment to increase lubricity and reduce friction
  • The strong web construction provides greater strength and rigidity to drill in hard to drill materials like stainless steel and titanium alloys
  • The buttressed cutting edge, with an acute rake, makes the BLITZ BIT® cut cleanly and accurately with less effort. The extra clearance behind the side margin reduces friction, enabling balanced cutting action with closer hole tolerances, at higher speeds
