The Milwaukee 48-89-2802 (29-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 degree 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 1/16 in, 5/64 in, 3/32 in, 7/64 in, 1/8 in, 9/64 in, 5/32 in, 11/64 in, 3/16 in, 13/64 in, 7/32 in, 15/64 in, 1/4 in, 17/64 in, 9/32 in, 19/64 in, 5/16 in, 21/64 in, 11/32 in, 23/64 in, 3/8 in, 25/64 in, 13/32 in, 27/64 in, 7/16 in, 29/64 in, 15/32 in, 31/64 in, and 1/2 in.

  • Extreme durability: thicker web provides greater strength and longer life
  • Fast, accurate drilling: 135 degree 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 resistant: black oxide coating provides lubricity and resists corrosion of the bit

Rated 4.4 out of 5 by 11 reviewers.
Rated 5.0 out of 5.0 by Great! These drill bits work very well. Have not had any issues with them. March 3, 2015
Rated 1.0 out of 5.0 by Bit snapped in half drilling second hole 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. October 2, 2014
Rated 5.0 out of 5.0 by Every size and then some I like the fact these stay centered when you first start to drill.You get every size from 1/16" to 1/2" . Very sharp and a nice case to store them in. January 20, 2015
Rated 5.0 out of 5.0 by Good quality set I bought this drill bit set because I wanted a good quality set and was tired of fumbling through the loose mismatched set of dull bits I already had. The bits are pretty sharp and seem to hold their edge well, and drill through hardwood and soft easily, as well as plastics and even metal very well. I drilled through a half inch of cast iron without a problem and without oil fairly quickly. I have no sharpened these yet but because of their strength it seems they'll sharpen well. Also the case is actually designed fairly well and opens and closes without any trouble. May 10, 2013
Rated 4.0 out of 5.0 by great bit for the price A solid drill bit. great cant beat the price. July 29, 2014
Rated 4.0 out of 5.0 by Great bits but horrible box! Bits drill through 3/8 steel plate or cast iron without a problem but u need to start from the smallest bit and go one by one to your desired size. Don't skip sizes or u will regret it. The only thing that really bothers me is the box. Taking bits out and back in is better done with pliers or u will cut your fingers! February 21, 2014
Rated 4.0 out of 5.0 by pretty good product. love the bits. have drilled through metal, wood, and drywall. bits have maintained their sharpness from day 1. have had them about 3 months and use them almost every day. May 25, 2013
Rated 5.0 out of 5.0 by AwesomeI I needed a nice set of drills for precision work and I found them in this set. January 14, 2014
