Product OverviewThe Milwaukee 21-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.

I actually prefer their old cases with the sliding latch, but it feels more durable than an old one I have. Really only complaint about the box is it's bulky. At 2" thick, it's probably designed to match up with something in the Packout line, but it takes up a good bit more space than my 10-15 year old 15 piece set in one of my bags.
For an economical Chinese bit that holds up well [youtube.com], search for the DeWalt DWA1184 series... And since he tested the black oxide like the OP Milwaukee are, the titanium coated in same model number are even better. Here is the 14pc set [homedepot.com], but they go up to 21pc and more.
PS: We use Hanson and Triumph drill bits that we buy direct, but when on a job site and need a bit, the DeWalt will get you by.

Just watch the video.... [youtube.com]and if not sure which model, go down to the link section and check the model from the seller.

For a 1/2" bit, that is a pretty good price, but be careful with steel that it does not catch and break off that shank if you need it for an impact. Me, I would hope it did break, or cut it off to use the full shank in a regular drill.
When I do that...it changes back to the $29 price.

Have I used the Milwaukee cobalt - no I have not used them just saying comparing apples to tomatoes or whatever.
The project farm I did not watch this time did in past - says the very expensive Bosch are tops or the dewalt for cheap....
The Bosch tested are cobalt of course they will be better
oh and edit snagged one set for hopefully moderate use for cheap.
wish there were good sales on cobalt bits particularly large ones
