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 degree 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 reduced shank won't slip in the drill chuck.

    Comments about Milwaukee 29-Piece Thunderbolt Black Oxide Drill Bit Set:

    Used a 27/64 bit to drill a hole in an acrylic pen blank. On the first blank it drilled a nice clean hole. On the second blank the bit seized and snapped in two.

    Generally I have had good success with Milwaukee products. Right now I am considering this product failure a fluke. Too early to provide any type of recommendation, will wait to see how the remaining bits perform but I would say I am disappointed.


    great buy
