Milwaukee 7/64" Thunderbolt Black Oxide Drill Bit
Description
The Milwaukee Thunderbolt 7/64" Black Oxide Drill Bit is engineered for extreme durability in demanding drilling scenarios. The Thunderbolt web features a thicker core than standard drill bits, providing the strength needed to resist side-load breakage when drilling at angles or through tough materials. A parabolic flute geometry clears chips and debris from the hole quickly, keeping the cutting edge cooler and helping preserve bit life over repeated use. The 135° split point tip starts on contact, preventing the bit from walking across the workpiece, even on curved surfaces. Milwaukee recommends the Thunderbolt line for portable drill use, as the bit requires less drilling pressure than conventional designs. A black oxide finish adds lubricity to each cut while guarding against corrosion.
