I have a vintage Milwaukee Thunderbolt Black Oxide 21-piece drill bit set for sale. Features a thicker Thunderbolt web core for enhanced strength and protection against side-load breakage. The black oxide coating reduces heat build-up and provides corrosion resistance, extending the life of the bits. The 135-degree split point tip ensures a precision start and prevents the bit from "walking" on the work surface. Parabolic flutes clear chips and debris faster to keep the bit cool. The bits have a 3-flat Secure-Grip shank to reduce slipping in the chuck.

The item is in excellent condition; however, the 3/8 and ½ drill bits are missing. The rest of the drill bits show very little use.

The locking plastic case is approximately 7” long and 3.5” wide; all drill bits fit neatly inside the case.

Comes from a clean, pet-free, kid-free, smoke-free home.
