Great step bits For electricians
These are great bits if you are an electrician as they are quick to cut through thin gauge steel or aluminum for connectors.

Good Value & Clean Cuts
The bits seems sturdy. I've drilled many different materials with great success (plastic, wood, and metal) it makes very clean holes and suspect the bits will last a long time. My only complaint is the letters for the hole sizes on the bits are hard to read, and the font has already worn off after a few uses. Kind of expected though so it's not a big deal.
