These work flawlessly. Drill your pilot holes and understand how to use them and you'll be fu-----, I mean, fixing up things in no time! Handled my Hyundai fenders, sheet metal and plastic, with ease. I found the bit with more spaced out steps better for my application. Like butter, but better. And use some common sense... drilling metal with metal gets hot. So good.

Zero stars. Very terrible quality, two of three bits burnt on first use. Very disappointing.

Can’t believe I waited my whole life to get theses things, finally. Sheesh. I also can’t know how these measure up to competing versions but the ones I got worked brilliantly to make perfect circle 9/16 to 3/4 holes in my Pelican cases (for making DIY solar battery banks).I don’t know my method was necessary or just my OCD, but to be safe, I used my own 1/16 (tiny) drill bit to start the hole (for precision centering) and then worked up to a 5/64 (or something like a 7/64) before moving up to these drill bits.From there I just stepped my way up, going from the smallest bit, skipping over the skinny - tall bit, and then going to the widest bit to eventually make 3/4 holes.I also like that this kind of bit creates debris that is easy to clean up (long curly pieces of plastic).Pictured is the final result of the SAE port I installed into the hole I drilled, the bits and pouch (also paper template I make to pre mark the hole). Unfortunately, I didn’t think to take a picture before installing the port but if I do pull it all apart, I will update this post.My only regret is not getting a set of these sooner because of the time-savings alone.Writing this review because it is seldom that I’m this happy with a purchase, lol. Also was not expecting the divider pouch which my ODC also loves.

Good throw down for your 1/4" drive drill. Good for thin sheet metal, plastic, mounting switches, accessories, enlarging holes. Excellent for light duty applications.

Says it right in the description not suitable for stainless steel or other hard metals but they say this product is junk because they can't read the description. it cuts aluminum like a dream mostly use it for drilling plastics to run wires
