Don’t rely on the pictures, check the description

The item’s pictures show that it comes with a bit that has a 25mm max step size. I ordered these for that drill bit. After receiving the drill bits, I discovered that it doesn’t include a 25mm bit. The description of the sizes is accurate though, so don’t rely on the photos. I kept the set because I needed them but I would’ve returned them if I had more time.

Pros
  • Bought these to drill parking sensors holes on a bumber.
Cons
  • Despite being marketed as a DIY woodworking tool, the HSS Titanium Coated Step Drill Bits Set may not be suitable for professional use or for heavy-duty drilling tasks due to its relatively low durability and longevity

Ease of drilling best in my review

These bits ate through metal like butter. I live how you can easily enlarge the hole step by step without switching bits.

Pros
  • Easily makes perfect holes to the exact diameter requested.
Cons
  • Did the job
