I couldn’t find my other set of 3 and needed them yesterday. So I got on Amazon and found these with next day delivery. Now it’s time to ruffle the feathers of the review checkers, these will get the job done, they come in a nice box with foam cutout for each bit. Haven’t used them yet because it’s been so hot, but I don’t think that I’ll have any issues with them.

Need to drill some holes in a steel rack unit 1U blank. This worked, albeit slowly. Bit jumped a bit before I drilled so it is slightly off. I suspect that is what the punch is for but I was lazy. I would not call the case “rugged” at all, but it is cute enough for good storage.

I bought this for basic EV plug installations. I just needed an affordable step bit to just be able to make a legitimate hole inside an electrical panel or tesla wall connector housing. I use this with a milwaukee fuel hammer drill and I have zero issues. Keep in mind if you put too much stress on the step bit, the chuck may not unwind. Use common sense and safety and this product should give you your moneys worth.

I owned and operated a developmental machine shop for 30 years, working mostly with exotic alloys, but for some reason never tried a step-drill. Finally, I had a small job at home that required putting a couple of holes in sheet metal in an awkward location and decided to give these a try. I was skeptical of the quality at this price. Fortunately, the drill size I needed to use worked beautifully. I ended up with a couple of nice clean holes. Drilling 2 holes didn't seem to affect the step-drill in any way, but I can't suggest how these bits would hold up under sustained use or with exotic alloys. As with any drill bit, some cutting oil will diminish the heat build-up at the cutting edge and extend the life of the tool. I only needed the one size of bit, so the extra were a bonus. Definitely worth the price for the job I needed to do.

I've bought the expensive uni-bits way too many times. They wear out so fast and for the price they are not worth it .but these right here last so long and you get a variety of sizes for less than half the cost of the expensive ones

High quality kit and it’s nice that it comes with a case. I mostly use them on sheet metal for HVAC

I needed to enlarge eight 1/2" holes to 3/4", in some mild steel square tubing. By working slowly, and using plenty of cutting oil, this bit did the job. The bit had some damage, but not too bad. Since this is my first step bit, I can't compare it to any other brands. It was cheap and did the job. GOOD ENOUGH!
