Broke after drilling 7 holes

Very disappointed with the quality of these bits. I received them on Saturday and proceeded to drill holes to attach the bike rack to the concrete floor. The first 7 holes are drilled like a champion. On the 8th hole - it broke in the hole - there is no way to pull it out. That's a 5'2" woman, so I'm pretty sure I didn't rape the puncher and it shouldn't have broken. By the way, I'm suspicious because of the age of the drills - note the rust on the drills. and the photo was taken on Sunday - 1โ€ฆ

Pros
  • Wear indicator: For exact hole diameter
Cons
  • Out of fashion

Durable drills! for masonry bits

My days of buying cheap drills are over. I'm building a deck where I need to attach planks to a concrete foundation. To be honest I was scared of this part because my previous masonry experience was extremely disappointing. The process just hit my arms and shoulders, and I ended up just burning my cheap beats. These beats are different. I wouldn't say they cut through concrete like butter. But once installed, they drill pretty well. I still have a lot to do, but I think this is perhaps theโ€ฆ

Pros
  • Four-edged design removes debris for fast, efficient drilling.
Cons
  • Questionable purchase for older people

ENGLISH BIT, GO IN CONCRETE WITH A GOOD DRILL

So I bought these bits after trying a Chinese bit I bought from Lowes. The Chinese part, as I expected, turned out to be frankly rubbish. This is the real deal with an excellent guarantee from DeWalt. Unfortunately, I first put them in a cheap Skil impact drill (that's just a name now, not the old Skil quality) and they kept twisting out of the drill chuck. Returned the drill, tried my son-in-law's American made drill. No problem. So don't skimp on a drill bit or anything when trying to drillโ€ฆ

Pros
  • Carbide tip maximizes carbide contact with the surface for longer bit life.
Cons
  • Ugly packaging
