REINFORCED WEB GEOMETRY FOR MAXIMUM SIDE-LOAD RESISTANCE
Engineered for the high-torque demands of professional drilling, the Milwaukee Thunderbolt Black Oxide bit features a specialized thicker core that significantly increases structural integrity. This reinforced web design is specifically built to withstand the side-load forces that typically cause standard bits to snap during deep-hole applications or when drilling through curved surfaces. The parabolic flute geometry optimizes chip evacuation, preventing heat buildup and friction to maintain a cool cutting edge, while the 135-degree split point ensures an immediate start without the need for a center punch.
- / Thunderbolt® Web Design: Thicker core provides ultimate strength and protects against breakage during aggressive drilling.
- / 135° Split Point: Precision tip starts on contact to prevent walking and ensure accurate hole placement on flat or curved materials.
- / Parabolic Flute Geometry: Clears chips and debris rapidly to keep the bit cool and extend overall tool life.
- / 3-Flat Secure-Grip™ Shank: Eliminates bit slippage in the chuck for maximum torque transfer and control.
- / Black Oxide Coating: Provides superior lubricity and corrosion resistance for long-term durability in metal and wood.
