Description
Milwaukee Thunderbolt black oxide jobber length drill bits are built for extreme durability and long life. The Thunderbolt has a thicker core than a standard drill bit, that provides ultimate strength and protects against side-load breakage.
A parabolic flute form clears chips and debris fast to keep the bit cool. A precision start, 135 split point tip starts on contact to help the bit from walking for fast accurate holes. Excellent for drilling curved surfaces, requires less effort to drill and is recommended for use with portable drills.
