NEIKO 10181A Step Drill Bit Set, 3 Piece, Spiral Grooved for Faster Drilling, Step Bits for Stainless Steel, Metal, Wood, Plastic, Unibit Cone Drill Bits with 31 Step Sizes Total

This set provides everything most people would need. It’s a good value for what you get. I’ll update this if I can once I know how they last however, I am happy with the purchase.

Deeeeez boys CUT. Look for the price, nothing is beating the quality. Sure go with a bigger brand name, but you could buy this set 3 times before you’d clear the value of a different brand.

The shipping was fast, as expected a nice and shiny set of hole makers. I put them to the test come the next work day. Sharp and durable (if used in the right way). All great until you find the tip of the smallest bit broke off. Not sure when and where but to my dismay one bit was no longer useable. I would recommend this set for light to medium light work.

Perfect size holes

Spiral step bit drill fast and last lt

These bits technically are functional as advertised, but they definitely don't even come close to the legit name brands. If you're working with wood, plastic, or a soft metal these are perfectly fine. but if you're working with 1/8 inch steel or thicker, these things will try to break your arm. The metal comes off as tiny chips instead of little curly spirals, that should tell you everything. I only used the smallest bit to test out, and it was not pleasant. There's no way I'd use one of the wider bits with the metal I'm drilling. You'd probably break your arm or your drill with a powerful enough tool.

exactly as advertised

I do HVAC installs and have only used this a handful of times and it's too dull to cut anything. Was just trying to widen some holes in an electrical box today to hook up some whips and this died on the fourth one. For some products it really does make sense to get a higher quality, and this is one of those.

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

Looking good item. Hopefully they last long

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