Milwaukee Thunderbolt Black Oxide 15/32" Drill Bit 48-89-2736
ENGINEERED FOR EXTREME RIGIDITY AND HIGH-TORQUE LOADS
When drilling through structural steel or thick timber with a portable drill, the primary failure point is often side-load breakage. The Milwaukee Thunderbolt® 15/32" drill bit addresses this with a significantly thicker core than standard jobber bits, providing the mechanical strength required to resist snapping during deep-hole applications. The parabolic flute geometry is specifically tuned for rapid chip evacuation, preventing heat buildup and binding. For professionals working with 3/8" chucks, the reduced Secure-Grip™ shank ensures that this larger diameter bit remains locked in place, delivering maximum torque transfer without the risk of the bit spinning in the chuck under heavy load.
- / Thunderbolt Web Design: Features a thicker core to provide ultimate strength and protect against side-load breakage in demanding materials.
- / 135° Split Point Tip: Delivers a precision start on contact, preventing bit walking and eliminating the need for a center punch.
- / 3-Flat Secure-Grip™ Shank: Engineered with three flat sides to provide a rock-solid connection in the drill chuck, preventing slipping during high-torque drilling.
- / Parabolic Flute Form: Clears chips and debris faster than standard flutes, reducing friction and heat for a longer tool life.
