Milwaukee® Thunderbolt® Black Oxide Jobber length drill bits are designed for
extreme durability and long life. The Thunderbolt® web features a thicker core
than a standard drill bit, which provides ultimate strength and protects against
side-load breakage. A specially designed parabolic flute form clears chips and
debris fast to keep the bit cool. A precision start, 135 Split Point tip starts on
contact to keep the bit from walking for fast accurate holes. Excellent for drilling
on curved surfaces, requires less effort to drill and is highly recommended for
use with portable drills. The 3-Flat Secure-Grip shank won't slip in the drill
chuck. Reduced shank diameter for use in 3/8" chucks.
