Review: Absolutely best bits I own - These relatively inexpensive bits outperform very high dollar carbide machinist bits, and other much more expensive cobalt bits. The cut so fast that the material barely has any chance to get hot which makes them last forever. I've been using them not for several months and I am very sincerely impressed. It's really hard to trust sellers these days. I think I paid 60 bucks to try them in my body shop just as a chance they might work on the lighter sheet metal and they performed so well and lasted so long I have started using them in my machine shop. They are suitable for cutting harder than mild steel, alloys and stainless with no issue whatsoever. I cannot speak highly enough of how surprised and utterly impressed I am with the performance. The most surprising part is the cost! They are the cheapest bits I own and they are also the best drill bits I own! I'm putting together a list to start replacing my professional machinist quality drill bits with these as they go bad and dull. They cost less than sharpening my bits and I have yet to dull any of these as of yet. Very surprised, impressed, and happy with them! I wish more things were like this. I'm happy I took a chance and bought these taking a low risk chance that had really taught me a wonderful lesson.
Review: HIGH QUALITY, cuts dang fast, love it, still use drill oil with it, doesnt take much - High value, easy to use, WORKS FANTASTIC. had to drill holes into steel trailer, after using a normal drill bit I purchased this bit. AMAZING. would advise to use drill oil, I just dipped the tip into the bottom I got at Home Depot, keeps the bit cooler, cuts easier, and doesn't get the metal your drilling into as hot. Never used one of these STEP BITS before. DEFINITE MUST. I have had no problems with this brand. cut speed is INCREDIBLE.

### ⭐⭐⭐⭐⭐ Well Made
*by S***A on November 7, 2025*

This tool definitely helped me with what I needed. I have a smaller stepper drill bit and could not open a big enough hole for the work I was doing to my car. The drill bit is very sturdy and cuts through metal pretty easy.
