NEIKO 10180A Steel Spiral Quick-Change Step Drill Bit for Metal with 4-Flute Spiral Grooved Design, Nitride-Coated High-Speed Steel Multitool with 12 Sizes in 1 Step Bit, Unibit, Hole Drill Bit

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.

I'm an HVAC installer and use this on a regular basis (2-8x a week) and it works really well on sheet metal and furnaces. Will have to see how long it'll go but so far very nice for the money. Recommended

I purchased the NEIKO 10194A Titanium Step Drill Bit, and I must say I'm not extremely satisfied with its performance. This versatile tool has become an essential part of my toolkit for both woodworking and metalworking projects. What sets it apart from other step drill bits is its high-speed alloy-steel construction, which ensures durability and longevity.One of the standout features of this step drill bit is its ability to expand holes in various sizes. With 10 step sizes ranging from 1/4 inch to 1 3/8 inches, it covers a wide range of hole diameters, making it incredibly versatile. Whether I'm working on a small DIY project or a larger construction task, this drill bit has got me covered.The titanium coating not only enhances its durability but also ensures smooth and clean cuts through wood and metal. I've noticed that it reduces friction, which means less effort is required when drilling, making my work more efficient.I appreciate the precision and accuracy I can achieve with the NEIKO 10194A Titanium Step Drill Bit. It's designed to create clean and uniform holes, which is crucial for a professional finish. Plus, the ergonomic design of the bit makes it comfortable to handle during extended use.Overall, I highly recommend the NEIKO 10194A Titanium Step Drill Bit to anyone in need of a reliable and versatile drilling tool. It's made my projects easier, faster, and more enjoyable, and I couldn't be happier with the results it delivers. If you're looking for a high-quality step drill bit, this one should be at the top of your list.

I have tried several brands of the cheap step bits, and they all burn and dull very quickly. The best set I found was D*walt (I have 2 sets if that says anything). My problem was I needed a larger size my set didn’t go up to. I bought this as I only needed to drill 3 holes and figured if it dulled, it was a cheap throwaway that wouldn’t hurt my wallet. I was surprised after 3 holes into 1/8” mild steel, it is still extremely sharp.

NEIKO 10181A Step Drill Bit Set are durable accurate and sharp. At this price point, they way exceeded my expectations. I have used other brands at a much higher price that did not perform nearly as well or nearly as long. Great Buy!!

Great bit for step enlarging a hole. Used on a musical instrument and needed a smooth, one shot solution that wouldn't catch or ruin wood. This worked well.

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.

Well engineered, works for my needs

Si Me Gusto Perfora Muy Bien el Metal,Madera, Aluminio Etc.

Buena calidad por el precio y el punzón funciona muy bien y es cómodo

He estado haciendo unas repisas de metal y me han servido muy bien estas brocas cónicas. No espero que duren una eternidad pero hasta ahora han aguantado bien. Unos 50 hoyos en PTR calibre 14. En cada perforación le pongo a la broca un chorrito de WD40 pa que me ayude a que no se caliente tanto y pierdan el filo.
