Milwaukee 25/64" THUNDERBOLT® Black Oxide Drill Bit

Milwaukee 25/64" Thunderbolt Black Oxide drill bits are engineered for exceptional durability and long-lasting performance. Featuring the Thunderbolt web with a thicker core than standard drill bits, these bits offer superior strength and resistance to side-load breakage. The specially designed parabolic flute rapidly clears chips, while the 3-flat Secure-Grip™ shank ensures a firm hold in the drill chuck. The 135° split point tip provides a precise start and prevents walking, enabling fast and accurate hole drilling. Ideal for curved surfaces, these black oxide bits require less effort when drilling through metal, wood, and PVC, making them highly suitable for use with portable drills. Model Number: 48-89-2731
