Milwaukee 15/16" Thunderbolt Silver & Deming Black Oxide Drill Bit 48-89-2752
INDUSTRIAL-GRADE BORING FOR HIGH-TENSILE STEEL AND CAST IRON
Engineered for the rigorous demands of industrial hole-making, the Milwaukee Thunderbolt Silver & Deming drill bit features a reinforced core that provides a significant mechanical advantage over standard twist bits. The Thunderbolt web design is engineered with a thicker cross-section to resist side-load breakage, ensuring long-term professional ROI when boring through stainless steel and cast iron. By utilizing a parabolic flute geometry, this bit maximizes chip ejection to mitigate heat buildup, which is the primary cause of premature bit failure in high-torque applications. The 1/2-inch reduced shank allows for large-diameter boring using standard handheld drills, while the integrated 3-flat grip ensures that the torque generated by the tool is transferred directly to the cutting surface without slippage in the chuck.
- / 135° Split Point Tip starts on contact to eliminate walking and the need for a center punch in hard metals.
- / Thunderbolt Web Design features a thicker core for increased strength and protection against flute breakage.
- / 3-Flat Secure-Grip™ Shank prevents the bit from spinning in the jawed chuck during high-load drilling.
- / Black Oxide Coating provides superior lubricity and corrosion resistance for extended tool life in wet or dry conditions.
- / Parabolic Flute Geometry clears chips rapidly to prevent clogging and reduce frictional heat.
