Milwaukee 13/64" Thunderbolt Black Oxide Drill Bit 48-89-2829
MAXIMUM CORE STRENGTH FOR HIGH-STRESS DRILLING APPLICATIONS
When you're pushing a drill bit through thick steel or curved surfaces, the most common failure point is side-load breakage. The Milwaukee Thunderbolt design addresses this with a significantly thicker core than standard jobber bits. This increased web thickness provides the structural integrity needed to resist snapping under heavy pressure. The 135-degree split point is critical for professional accuracy; it bites into the material immediately without walking, which is essential when drilling into pipes or structural beams where precision is non-negotiable. Combined with a parabolic flute that clears chips rapidly to prevent heat buildup, these bits are engineered for long-term ROI in a professional's daily kit.
- / Thunderbolt Web: Thicker core increases bit strength and prevents breakage during high-torque applications.
- / 135° Split Point: Precision tip starts on contact, eliminating the need for a center punch and preventing bit walk.
- / Parabolic Flute: Engineered geometry clears chips and heat rapidly, extending bit life in continuous use.
- / 3-Flat Secure-Grip: Prevents the bit from spinning in the chuck, ensuring maximum power transfer to the cutting edge.
- / Black Oxide Coating: Provides essential lubricity and corrosion resistance for long-term jobsite durability.
