    5.0 out of 5 stars Makes your holes bigger and better

    A.C. · March 27, 2025

    (function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } I’ve been using this KSEIBI step drill bit set for about a month now on different home metalworking projects, and I’m really happy with how they’ve held up. I mostly work on DIY repairs in the garage — stuff like fixing brackets, making cleaner holes in sheet metal, and modifying hardware — and these bits have made that way easier.They cut smooth and don’t grab or jump when I start drilling, which is something I’ve had trouble with in cheaper sets. I’ve used them on aluminum, steel, and even some old brackets I wasn’t sure about, and they still feel sharp. For the price, they’ve definitely delivered more than expected — really solid value for the money.Functionality-wise, they hit the mark. The steps are clearly marked, so it’s easy to stop at the right size without over-drilling. The metal feels durable, and they haven’t overheated or dulled quickly, even with frequent use. I haven’t had to sharpen them yet, which says a lot.If you do light to medium-duty metal work at home, this set punches well above its weight. Solid performance and a good buy all around.

    Great drill bits, case is quite nice but I’m not sure it couldn’t be smaller, though the size isn’t terrible it’s not real compact. Fantastic bits and the case isn’t required if space is an issue.I will be ordering a set for my son.

    Working great

    4.0 out of 5 stars Work good, but not indestructable

    J.T. · January 13, 2025

    These things did great going through most of what I used them on, but I'd question the impact rating. I broke a bit in my first set trying to open up a hole on a trailer for a wiring harness. When built they used a torch to blow a hole in the metal. I wanted a nicer rounded hole for passing protective sleeving through. Was using the bit in my impact driver because drill was too long to fit in area. Bit promptly caught and snapped off at the shank.Was still in return window and Bolo or seller was quick to replace. Haven't had any more issues, but also haven't put them into a similar situation.

    5.0 out of 5 stars Good stuff!!

    M.Á.S. · April 25, 2025

    5.0 out of 5 stars Amazing metal drill bit

    T. · December 4, 2024

    Was a little skeptical with the step bit, but most of the reviews were great and let me tell you what they were not wrong. I’ve used this bit for the past couple of months on several different projects and with a little cutting lubrication this bit has yet to fail me one time I mounted a trailer hitch on an older F250 that required six holes to be drilled through the frame. In this thing handled it with ease on an impact gun then I drilled another eight holes through steel on my trailer to mount the winch then in additional eight more holes on the tongue to mount electric jack and toolbox a little cutting lube and this thing handles like a champ, and it’s still not dull yet would definitely definitely recommend
