Product Overview

The 21-Piece Thunderbolt Black Oxide Drill Bit Set offers convenience and heavy-duty performance on the jobsite. Milwaukee Thunderbolt Black Oxide drill bits are designed for extreme durability and long life. 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 fast, while the 3-Flat Secure-Grip shank holds the bit firmly in the drill chuck. The 135° split point tip delivers a precision start and prevents walking for fast, accurate holes. Effective for drilling on curved surfaces, Milwaukee Thunderbolt Black Oxide bits require less effort to drill through metal, wood and PVC, and are highly recommended for use with portable drills. The set comes in a resilient case and includes bit sizes (2) 1/16", (2)5/64", 3/32", 7/64", (2) 1/8", 9/64", 5/32", 11/64", (2) 3/16", 13/64", 7/32", 15/64", (2) 1/4", 5/16", 3/8", and 1/2".

  • Extreme durability: A thicker web provides strength and long life
  • Fast, accurate drilling: 135° split-point tip starts on contact to prevent walking, while the parabolic flute clears chips fast
  • Reduced slipping: 3-flat secure-grip shank holds the bit firmly in the drill chuck
  • Corrosion resistance: black oxide coating provides lubricity and resists corrosion of the bit
  • Flexibility with projects: includes 21 twist drill bits in jobber length bit sizes for a variety of applications
  • Various sizes: bit sizes range from 1/16 in. to 1/2 in.

Customer Reviews

Thunderbolt Black Oxide Drill Bit Set (21-Piece) is rated 4.1 out of 5 by 23.
Rated 5 out of 5 by from Great Bits! Great bits for the price but unfortunately my home depot decided to stop carrying them. Every time depot has something good they decide to get rid of it. It's very obvious that the people making these decisions are sitting behind a desk somewhere and have never done a day of manual labor in their entire lives. Instead of always worrying about what bits to get to save a couple cents worry about what customers want.

Rated 4 out of 5 by from Good set of drills for a good price. I bought these as an add on to an order of things I needed. Surprised by the low price and free shipping (because of my order total) was a bonus. These are not high end drill bits as evidence by somewhat rapid dulling when drilling steel and tendency of smaller bits to bend. But, for the money the are great!

Rated 5 out of 5 by from These drill bits worked good in both wood and metal. Had a job requiring me to drill multiple holes and sizes in wood and soft steel pipe. The real challenge for the bits was the pipe. The 3/8 bit was able to drill 4 holes through 2' pipe with no cutting lubricant at a slow speed and had no detectable dulling of the edge.

Rated 5 out of 5 by from Very pleased I needed some new drill bits for the new Milwaukee drill impact driver I got over Christmas. The case is sturdy with a good latch and it fits nicely into my tool bag for easy transportation. I've only used the bits on wood so far but can say that they cut well and show no sign of wear or chipping. I would definitely buy these again. Especially since I got them on sale for a steal!

Rated 4 out of 5 by from Good drill set I bought this set strictly for wood, and they've been great. Haven't had to sharpen them yet and I've used them in hard and dense woods such as cocobolo and bubinga. I can't speak to their ability in plastic or metal, but I bought the Rigid Cobalt set specifically for that, something I highly recommend, keeping a separate wood and separate metal drill set.
