Description of ๐Ÿ”ง IRWIN Tools Black Oxide, Model 4935643

These drill bits use a 135ยฐ split-point tip to start drilling quickly and minimize walking. Each drill bit is made with high-speed steel with a black oxide treatment to resist corroding. 1/4-inch hex shank works in most Lock-n-Load quick-change extensions as well as most drill chucks. Suitable applications include automotive, maintenance and repair, portable drills and stationary drill presses. 12-piece set includes 1/16", 5/64", 3/32", 7/64", 1/8" (2), 9/64", 5/32", 3/16", 7/32" and 1/4" drill bits and a Lock-n-Load quick-change extension.

Look for impact ready bits instead unless you need a case

I love this stylish bit with a quick change shank that fits screwdrivers. And I love the business. HOWEVER, these drills are upset on a quick-change shank. They don't hold up well when drilling metal, and the larger ones tend to slip in the shank even when drilling wood. The idea is awesome, but do yourself a favor and get your drum beats ready. Irwin makes them for a reasonable price. They are only slightly larger but strong with a hex shank to keep them in place. They can break if you're notโ€ฆ

Hex Shank Bits - Love Them

Great set. I build a lot and have tried many drills. I was impressed with this set. I like having the bits in an "index" for easy selection, so I like the sturdy case and easy bit extraction. The hexagonal shank is of great importance and is important to me for quick insertion into the drill chuck and for stabilizing the drill under load during use. The quick release adapter is a nice bonus, although I didn't use it much. After some comparison shopping I found the price of this set to be quiteโ€ฆ

Pros
  • High marks for grip and durability from testers
Cons
  • Not as thick as other bits

Edited 5/16/13 - Not as good as I'd like

5/16/13 - I used one of the smaller ones and barely touched the plastic with it and it broke. Not sure if it's due to landing in the feed? I've used thinner bits in a regular chuck with no problems. In fact, I mostly break them when I tilt the drill and almost never while I'm working. But this little piece broke immediately in the hex shank configuration. So now I guess it's not that hot. You can get a really good hex shank drill chuck that will work with extra fine bits. Instead I used it with
