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

The Milwaukee Thunderbolt 1/4" x 4" High Speed Steel Pilot Bit is engineered for extreme durability and long life in demanding drilling applications. A tapered web design uses a thicker core than standard pilot bits, reinforcing the bit against side-load breakage. The parabolic flute form channels chips and debris away from the cutting edge quickly, helping the bit run cooler under sustained use. A precision-ground 135° split point tip starts on contact, preventing the bit from walking so every hole lands where intended. The 3-flat shank seats firmly in any arbor or chuck without slipping under torque. The bit performs well on curved and angled surfaces with reduced downward pressure, making it a strong match for portable drills. A 1/4" bit diameter pairs with a 3" drilling depth and 5.7" overall length for versatile pilot hole work.
