PRODUCT OVERVIEW

Model # 48-89-2801

Internet # 100670139

Enjoy the convenience and heavy-duty performance of the Milwaukee Thunderbolt Black Oxide Drill Bit Set. These drill bits were designed for extreme durability and long life. Use them to drill curved surfaces, as they require less effort to drill through wood, metal and PVC, and are highly recommended for use with portable drills. The Thunderbolt web features a thick core for ultimate strength and protection 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 gives you a precision start and prevents walking for fast, accurate holes. The set comes in a resilient case and includes the following bits: two 1/16 in., two 5/64 in., 3/32 in., 7/64 in., two 1/8 in., 9/64 in., 5/32 in., 11/64 in., two 3/16 in., 13/64 in., 7/32 in., 15/64 in., two 1/4 in., 5/16 in., 3/8 in., and 1/2 in.

  • 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

Rated 4.1 out of 5 by 23 reviewers.
Rated 5.0 out of 5.0 by 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. January 3, 2016
Rated 4.0 out of 5.0 by Nice bits... Usually not a lot to say about drill bits, but these work really well. Have used on sheet metal (gutters) and plastic. And they come in a very nice case!! December 8, 2015
Rated 4.0 out of 5.0 by 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. December 6, 2015
Rated 5.0 out of 5.0 by Just what I wanted!! I needed new drill bits & wanted ones that would last. Price was right and the bits are sharp. October 27, 2015
Rated 4.0 out of 5.0 by Good price and Good quality! Good set of drill bits at a great price. It's just the right size to carry around in a small tool box for those emergency needs or your everyday around the house tasks. October 20, 2015
Rated 5.0 out of 5.0 by super good price!!! these are great drill bits, holds up very well as long as you take care to use cutting oil and the correct speed. been using these bits on stainless steel and are doing a great job. these drill bits are equal to your high priced bits. cant go wrong for the price and home depot has them in stock all the time. September 22, 2015
Rated 4.0 out of 5.0 by Really good value in this set I use these bits to drill holes in steel rifle barrels. They have held up very well and the tips are sharp enough to prevent the bit from "walking" off the target point; requiring only a light tap from an auto-punch. They were on sale when I purchased too, which was a bonus. I believe this bit set is an excellent value. August 5, 2015
Rated 4.0 out of 5.0 by So far so good I have only used the bigger sizes a couple of times but they seem to hold up to the UHMW plastic that I am putting holes in. August 25, 2015
