  • Having a solid case to keep the bits nice and sharp vs just rolling around with other metal bits. Very versatile, do-it-all kit.
  • If you're going for smooth and efficient these will blow through most Stainless Steel/Metal Sheet/Wood/Plastic/Aluminum Sheet/Copper and other metal sheets at high speed like butter.
  • Whether you're working on a big project or a quick fix, our step drill bits are your go-to tools. MABLEVI will repair and replace any defect, without charge, and without waiting.

  • They don't work very well.
I use uni unibits on almost all jobs that I do. I have tried using them a few times now and each time I switch to my old ones. When I'm drilling my hole they get stuck and cause the drill to suddenly stop. There should be a smooth operation as the hole gets to the size hole you want. I went out and bought a different set and they are working great. Don't buy unless you want to get frustrated drilling your hole. ... show more
