The MILWAUKEE 29 piece Thunderbolt Black Oxide Drill Bit Set offers convenience and heavy-duty performance on the job site. These drill bits are designed for extreme durability and long life. The Thunderbolt web features a thicker core to provide ultimate strength and protect against side-load breakage. Corrosion resistant coating provides lubricity and resists the corrosion of the tip. A specially designed parabolic flute form clears chips fast, while the 3-Flat Secure-Grip shank holds the drill bit firmly in the drill chuck. The 135° split point tip delivers a precision start and prevents walking for fast, accurate holes. The Milwaukee Thunderbolt Black Oxide bits are effective for drilling on curved surfaces and require less effort to drill through metal, wood, and PVC. The set comes in a resilient case and includes the following bits: 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.

There is nothing quite like having the right sharp drill bit when you need it.

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.

When you catch it on sale these are an awesome set of bits for what you get. 1st off as far as I’m concerned the case is amazing. It is the same style of case that milwaukie puts their screwdriver bits and assortments in only bigger. As far as the actual bits go all of them that I have used so far are extremely sharp. They are coated with some type of rust preventer I’m guessing. You can feel it a little bit on the bits when they are fresh and they are all a bit stuck in their holes at first. They should last a long time for general drilling if you know how to use drill bits and take care of them. Since these are black oxide bits and not cobalt ore tin coated or anything like that don’t expect to be blowing through stainless all day that’s not what these are for.
