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.

These bits can drill plastic, wood, non-ferrous metals and mild steel (not stainless steel or instrumental steel). This is typical for multi-purpose drill bits. Unlike my previous HSS bits, these stay sharp longer and do not break as often. I do not think I ever broke a bit larger than 5/64″, and even that happens rarely. I just keep a few extra bits of small sizes in case they break or get dull. For pilot holes, do not use 1/16″ bit if you do not have to. It is just too fragile, no matter of the manufacturer. Use 5/64″, at least.The plastic case this drill bit set comes with is not great, bits are hard to take out, and I find it too large. Let’s knock down one star for this. I use Huot metal box (drill index), and while it is not perfect either, I prefer it.Overall, these are great multi-purpose drill bits. I own two sets (one stays at home, one in the car). I also have select sizes of specialized drill bits (brad point for hardwood, cobalt for stainless steel, masonry, even solid carbide), but these bits are what I use most of the time.

This is a nice compact drill set that works great in a standard drill chuck or a quick release driver.

Good bits.

Drill bits are a good bargain. Cut mild steel very well and even better with lighter gauge materials. They also seam to keep a good edge for a long time.

SPECTACULAR!

Drill set included up to a 1/2 bit. Bits easily cut 8 holes in 1/4 in steel needed for lawn mower project. Quality + value = satisfied home owner!

All products were easy to assemble and work beautifully. Best product on market for the money.

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.

I’ve had a set of these drill bits for 4 years now. They are the best I’ve used hands down. I’ve drilled heavy ibeam, channel, truck chassis, stainless, spring steel, welded holes up and re-drilled the welded area, lent them to the apprentice, and all of which have been done at some stage with a Milwaukee fuel 18V cordless drill. Super stoked with this product. It’s all about how good you are with your trigger finger, how much weight to apply on the bit and how you sharpen the tip. I get pretty savage with these bits and they have lasted my punishment and the test of time.

Really nice drill bit set I like the Box red is good

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.

The bits themselves are adequate, but barely. Do not expect to drill metal with ANY hardness. The index is horrific. The bits are nearly welded in and either wear a Kevlar glove or buy massive amounts of BandAids when putting them back in.
