Product Overview

29/64" Cobalt SP Jobber Drill Bit with 3/8" Reduced Shank (6 Pack)

  • Bosch cobalt drill bits offer the best heat resistance and rigid thick web design for drilling in extremely hard and abrasive materials such as treated stainless steel (precipitation-hardened), cast iron and titanium
  • 135° split point starts on contact with no walking or skating and no center punch is required
  • A tough cobalt alloy delivers heat resistance up to 1100° Fahrenheit allowing the bit to perform for extended periods of time in the most abrasive materials without failing due to the high heat levels
  • Overall bit hardness of 66-68 HRC from the cobalt formulation gives the ability to penetrate exceptionally tough materials
  • High red hardness of cobalt steel permits speeds 30% higher than regular high speed steel drills
