Milwaukee 48-89-2840 3/8 in. Thunderbolt Black Oxide Drill Bit

Product Description

Milwaukee Thunderbolt black oxide jobber length drill bits are made for durability and long life. The Thunderbolt web has a thicker core than standard drill bits, providing strength to prevent side-load breakage. A parabolic flute clears chips and debris quickly to keep the bit cool. The 135-degree split point tip starts on contact, preventing the bit from walking for accurate holes. The design is effective for drilling on curved surfaces and is highly recommended for use with portable drills. The 3-flat secure-grip shank eliminates slipping in the drill chuck. The shank diameter is reduced for use with three-eighths inch chucks.

• Durability: thicker web increases strength and longevity
• Fast drilling: 135-degree split point tip prevents walking while the parabolic flute clears debris rapidly
