Milwaukee 48-89-2736 15/32" Thunderbolt® Black Oxide Drill Bit

Extreme durability: Thicker web provides greater strength and longer life. Fast, accurate drilling: 135° split point tip starts on contact to prevent walking, while the parabolic flute clears chips fast. Reduced slipping: 3-Flat Secure-Grip™ shank holds the bit firmly in the drill chuck. Versatile: Reduced shank diameter for use in 3/8" chucks. Corrosion resistant: Black oxide coating provides lubricity and resists corrosion of the bit.
