Milwaukee 19/64" THUNDERBOLT® Black Oxide Drill Bit (6 PK)

REINFORCED CORE TECHNOLOGY FOR HIGH-STRESS DRILLING

Engineered to withstand the mechanical rigors of high-torque portable drilling, the Milwaukee Thunderbolt® series redefines the structural integrity of the standard jobber bit. By utilizing a significantly thicker core—the Thunderbolt web—these bits provide superior torsional strength and resistance against side-load breakage, a common failure point when drilling through thick metal or curved surfaces. The parabolic flute geometry is specifically designed for rapid chip evacuation, preventing heat buildup at the cutting edge and maintaining drilling speed throughout the life of the bit.

• / Thunderbolt® Web Design: Features a reinforced thicker core to provide ultimate strength and protect against breakage during aggressive drilling.
• / 135° Split Point Tip: Delivers a precision start on contact, preventing the bit from walking and ensuring accurate hole placement without the need for a center punch.
• / 3-Flat Secure-Grip™ Shank: Engineered with three flat contact surfaces to prevent the bit from slipping in the chuck under high-torque loads.
• / Parabolic Flute Geometry: Optimized to clear chips and debris quickly, keeping the bit cool and extending the service life of the cutting edge.
• / Black Oxide Coating: Provides essential lubricity and corrosion resistance, reducing friction and heat during metal-to-metal contact.
