Cheap and effective but only slightly shorter life expectancy

Did the job I needed it for before it broke completely. It took both of the smaller drill bits to drill 9-10 holes fully into the porcelain tile to install a couple of anchor bolts. It did a good drilling job and the low price meant I was ok and expected the same. Will do the same and will buy more for the same purpose in the future if needed.

Pros
  • Pretty impressive
Cons
  • boring packaging

These drill bits are great

I am a contractor and need to install (3) handrails in (2) private bathrooms, paper towel dispensers, toilet paper dispensers, mirrors and other sanitary product containers Walls are ceramic. I haven't had any luck with the drill bits I bought from local hardware stores, I could never get them to drill (3) holes without burning through. I recently bought these drill bits because I had (4) 1/4" drill bits in the pack that I needed and I was hoping 4 would be enough. Now after drilling 56 holes…

Pros
  • Stylish and modern design
Cons
  • Slightly wrinkled

They're actually metric, but they're so cheap they're practically disposable

Tl;dr: They work great. They're metric, but they pierce through hardened steel well and are cheap enough that you won't feel bad after blowing one of them. I bought this set of bits along with some pure carbide twist drills. The four twist drill bits I bought cost over $100 and I ended up breaking one of the expensive drill bits while drilling hard steel (S35VN hardened to 60 HRC). I ended up with them and they dulled, but consider this set of bits did the job and cost less than half the price…

Pros
  • Very Good Price
Cons
  • Piggy Bank Price
