  • It’s great for sheet metal, aluminum sheets, wood chips, plastic, and wood board. It’s a perfect choice for DIY and engineering use.
  • Engraved Sizes Easily identify which size you need with the contrasted, laser-engraved sizes inside the step drill bit flute.
  • High-speed steel along with titanium coating ensures outstanding durability and sharpness, can reduce friction, and runs cooler.

Five Stars

My husband really enjoyed this! It's ideal for creating the necessary hole for our sink.

I bought this to assist in installing a spoiler on my CTS coupe, but I completed the job before they arrived. They seem like a comprehensive set with various sizes you might need and come with a nice case. I haven't tested them yet. If they hold up well, they deserve the four stars I've given them.
