Thunderbolt Black Oxide Drill Bits last longer and drill faster than standard drill bits

Meet your drill's new best friend. These bits are ideal for drilling on curved surfaces and feature a core that’s thicker than standard bits to protect against side-load breakage. The specially-designed parabolic flute clears chips fast to keep the bits cool and a 135°. split point keeps the bits from “walking” for faster starts. The unique 3-flat shank won't slip in the drill chuck. Reduced shank diameter for use in 3/8" chucks. For general purpose drilling in light gauge metal, high carbon steel, aluminum, wood, plastic and fiberglass.

Bits include: two 1/16", two 5/64", one 3/32", one 7/64", two 1/8", one 9/64", one 5/32, one 11/64, two 3/16", one 13/64", one 7/32" one 15/64", two 1/4", one 5/16" one 3/8" and one 1/2".
