works great

Great for electrical work. Only way to use a step bit is with an impact driver!

Phenomenal value for the price

I needed to drill a 1/2 hole in a 1/16 inch thick piece of curved stainless steel. This worked perfectly. It bit immediately with no skipping and drilled through the various step sizes with ease. Probably wouldn't be great for heavy gauge steel, but perfect for light steel and wood.

The media could not be loaded.

We were working on a craft project that required holes through small sheet metal covers to mount solar lights. The holes were 11/16 inch diameter and these step bits cut a nice, clean round hole in the metal. The bits have angled shafts to prevent rotation in the drill chuck, and seem sturdy and sharp. For cutting something thicker, like wood, I think it would work easier to see clearly when the various step levels occur, because you have more resistance. But overall these worked great for our project, and a new addition to the variety of drill bits we need and use around our DIY projects.

There was absolutely no way I was going to spend $70 at home depot for what they had. Got this one next-day on Amazon for 1/5 the cost and it worked perfectly for my single use requirement!!! Installed an Insinkerator Instant Hot/Cold faucet. Fantastic!

Excelente producto y práctico

Seems like a nice set of step drills. I used one of the drills for the first time recently, drilling holes thru some 15 gallon drums. Sure, they were only plastic drums, but they were pretty thick. Anyway, I popped holes using these and it was like a hot knife thru butter. Very sharp. I don't plan on using these for any drilling of extremely hard metal like stainless steel so I think they'll work perfect for my needs. Nice set for the price. I took off one star only because I don't know how they'll work for harder materials or how long they'll remain sharp. I'm happy with them.

I tessted this on a piece of three eight flat bar it cut through easy enough with a little cutting compound J managed to cut a hole the full diameter of the step bit great piece of kit.

Works well. hope it lasts long.

Have used these to drill out stainless allan key studs. With the appropriate drilling fluid, they were drilled out with ease. Very happy!

I bought this so I could put a new grommet into my Weber Smokey Mountain Smoker. My model was an older model and didn't come with the grommet that allows for temp probes to pass through and monitor the temp of the inside of the smoker and the meat being smoked. When I purchased the grommets (it came 2 to a pack), Amazon recommended this drill bit for making the hole in the smoker to allow for mounting the new grommet. I already have a drill bit like this one from a name brand, BUT it wasn't big enough to accommodate the grommet I was purchasing. So, since I needed this to make my project work and since it was about 25% of what I paid for my other one, I bought it. Also, I factored in that I was probably only going to need to use it once, ever, so it made sense to get this product at the same time of purchase as the grommets.When the grommets and drill bit arrived, I was pleased and excited. I cleaned up the outside of the smoker where I was going to drill and then put some painters tape over the designated spot to try and prevent the enamel from chipping. I then started to drill. The tape seemed like a good idea at the time, but the tape quickly peeled and got stuck in the drill bit. I eventually pulled the tape off completely about 1/3 of the way through for drilling. I needed to make a hole that is 1 and 1/4" in diameter, which was the second to last step on the bit. I was trying not to go too fast 'cause I was worried I would get overzealous and drill the hole too big and then I'd be Really Mad 'cause I would have messed up my smoker. So I took my time and kept on going. When I got about 3/4 of the way through, the bit was not very smooth - not like my other name brand bit. I was getting even more scared that I was going to mess up my smoker and it was making me nervous using this drill bit. However, I had already come this far and there was no turning back at this point. So, I pressed on, but gently.The biggest problem I was encountering was that the bit would catch on the opening it had created with each step that it passed through on the bit and I had to be careful not to cut my fingers, mess up my drill or mess up my smoker. It was frustrating because it wasn't a smooth drilling process at all. However, I eventually got to the stopping point and took the bit out. I could see a nasty burr of sharp metal hanging from the opening I had just created. So I put the drill on the other side of the hole and very gently drilled from that side just long enough to get rid of it and make the opening fairly smooth. Then, I was finally able to install the grommet and breathe a sigh of relief that I had not messed up my smoker.I share all of this with you, the reader, to let you know that this product did work, BUT it was not very smooth and if the name brand bit I had was big enough, I would gladly have used it instead. Knowing what I know now, I would caution you on purchasing this and remember my experience with this drill bit. It Can do the job, but you have to be super careful with it, or you might mess something up that you can't fix later and that would be very, very bad, I would imagine. I give this product 3/5 stars, because it did do the job and the price was nice, but you get what you pay for and you definitely have to be careful with it.
