About this item

  • Milwaukee Thunderbolt Cobalt drill bits are designed for extreme durability and long life in specialty applications
  • Milwaukee Thunderbolt Cobalt bits require less effort to drill through stainless steel
  • High alloy steel and cast iron


Milwaukee Thunderbolt Cobalt drill bits are designed for extreme durability and long life in specialty applications. The Thunderbolt web features a thicker core than a standard drill bit to provide ultimate strength and protect against side-load breakage. A specially designed parabolic flute form clears chips and debris fast to keep the bit cool. The 135ш split point tip delivers a precision start and prevents walking for fast, accurate holes. Effective for drilling on curved surfaces, Milwaukee Thunderbolt Cobalt bits require less effort to drill through stainless steel, high alloy steel and cast iron. Highly recommended for use with portable drills.

I've been testing various drills against hard steel on my drill press. My "hard steel" sample is a used Woods mower blade, about 1/4" thick. I previously tested a Milwaukee cobalt bit that had a "pilot point." Neither do the job. They both start out great but are completely dull after about 3/16" of cutting. They both drill mild steel ok. Bits that I found drill through the blade are made by Bosch, Irwin, and Century. Don't waste your money on this bit.
