Milwaukee 15/64" Thunderbolt Black Oxide Jobber Length Drill Bit (12-Pack) 48-89-2831

Milwaukee 15/64" Thunderbolt Black Oxide Jobber Length Drill Bit (12-Pack) 48-89-2831

ENGINEERED CORE STRENGTH FOR HIGH-STRESS DRILLING

The Milwaukee Thunderbolt series represents a significant advancement in drill bit geometry, specifically engineered to solve the primary failure point of standard bits: core snapping under side-load. By utilizing a thicker, reinforced web, these bits maintain structural integrity when drilling through heavy-gauge metals or when the drill is subjected to the inevitable lateral pressure of handheld operation. The black oxide coating serves a dual purpose, acting as a lubricant to reduce friction-induced heat while providing a critical barrier against oxidation in humid jobsite environments. For professionals cycling through high-volume drilling in steel, wood, or PVC, the parabolic flute design ensures that chips are evacuated efficiently, preventing the bit from binding and overheating during deep-hole applications.

  • / Thunderbolt Web design features a thicker core to provide ultimate strength and protection against breakage during aggressive side-loading.
  • / 135° Split Point tip enables a precision start on contact, eliminating bit walking on curved or hardened surfaces for faster, more accurate holes.
  • / Parabolic flute geometry facilitates rapid chip and debris removal, keeping the cutting edge cool and extending the service life of the bit.
  • / 3-Flat Secure-Grip shank prevents the bit from slipping in the chuck, ensuring maximum torque transfer during high-demand drilling.
