Milwaukee 15/32" THUNDERBOLT® Black Oxide Drill Bit (6 PK)

REINFORCED WEB GEOMETRY FOR AGGRESSIVE DRILLING APPLICATIONS

When you're pushing a high-torque drill to its limits, the weakest link is often the bit's core. The Milwaukee Thunderbolt series addresses this by utilizing a significantly thicker web than standard jobber bits, providing the structural integrity needed to withstand heavy side-load pressure without snapping. The 135-degree split point is a critical feature for professional users, ensuring the bit bites into the material immediately upon contact—even on curved or uneven surfaces—eliminating the need for a center punch. By combining a parabolic flute design for rapid chip evacuation with a black oxide coating for reduced friction, these bits maintain a lower operating temperature, which is the primary factor in extending the service life of high-speed steel in repetitive metal-drilling cycles.

• / Thunderbolt® Web: Engineered with a thicker core to provide ultimate strength and protection against side-load breakage during heavy-duty use.
• / 135° Split Point: Precision tip starts on contact to prevent bit walking, ensuring fast and accurate hole placement without a pilot hole.
• / Parabolic Flute Design: Clears chips and debris rapidly to keep the bit cool and prevent binding in deep-hole applications.
• / 3-Flat Secure-Grip™ Shank: Features three flat sides to provide a solid connection with the drill chuck, preventing slipping under high torque.
• / Black Oxide Coating: Provides essential lubricity and corrosion resistance, reducing heat buildup for a longer-lasting cutting edge.
