Hell of a deal for the price. Step bits always are a hit or miss. This was a hit for sure with it incredibly rigid design and high quality. It’s sharper than most. It has so many uses and functions. It works best with light weight metals but will drill through almost anything. I needed this for my shop and it has out some of my other bits to shame in performance.

A bargain step bit that performs very well!Step bits perform better in thinner metals and this one does that very well. The metal feels weird; yet it is durable. I used it several times and have not notice any degrade in performance. It does remain sharp. Once you place the bit at the location, it stays there with slight pressure. The drilled holes are clean. The quick release works well and it’s a plus.A very good bit!

This is a step drill bit for practically any size hole out of any material. I was really happy to get this. I've used it for wood and it works wonderful. I can just stop when the hole is big enough. I don't have to keep changing bits. Is machined well with no burrs and it cuts like butter.SPECIAL NOTE: As an approved Amazon Vine member with Gold status, I am trusted to select items for review (sometimes from a list of almost 130,000 options). Many of these items are new to the market, or a seller simply wants some additional exposure for their product. I am NOT required to review every item in exchange for receiving and trying it out. I only order products that are important to me (ones I know I have an interest in and will use), and always strive to provide an honest evaluation of my experience. I do not automatically give a 4- or 5-star review, because the community of Amazon purchasers deserve to know real thoughts and experiences. So, my reviews are always and only based on my use and testing of the product. In that you can trust 100%. It's also important to note that I pay almost 30% in federal income taxes for each item that I receive, whether I review it or not.

I tried this on an electrical panel and was pleasantly surprised at how well it drills, I didn't drill a pilot hole and it didn't need it, after drilling a few holes it seems nice and sharp unlike other cheap step drills...
