Milwaukee 49-56-8000 1/4" High Speed Steel Pilot Bit

Milwaukee Thunderbolt pilot bits are engineered for extreme durability and prolonged lifespan. Featuring a thicker core in the Thunderbolt web, these bits offer ultimate strength, effectively guarding against side-load breakage. The specially designed parabolic flute form swiftly clears chips and debris, ensuring efficient cooling during operation. With a precision start and a 135-degree split point tip, these bits initiate contact immediately, preventing bit wandering and ensuring fast, accurate hole drilling. The Thunderbolt tapered web enhances durability, while the 3-flat shank design prevents slipping in the arbor or chuck. These bits are particularly well-suited for drilling on curved surfaces, requiring less effort and highly recommended for use with portable drills.
