Works as intended. Coating held out great too!

Great deal. Low cost drill bits for metal. I used them to drill holes in my aluminum rain gutters.

Good tools, work very well. It has a short taping section, then you lit a bigger drill size.

I've had to use you several times to clean screw holes and make screw holes. The screws rusted out of the bathtub overflow plate so I used one of these to drill next to those and put the plate back on with a new set of screws. Now it's saved a whole bunch of time in a lot of misery because my options were to replace the tub shoe assembly overflow plate and cut a drywall hole behind the bathtub which would require to remove the back cabinet in the kitchen so I've bought multiple sets of these because I do maintenance and love these love these love these and did I say love these!!

Here’s a clearer, more concise version of your review with improved flow and readability, while keeping your original points and tone intact: > I’ve used taps for years, so this isn’t a case of operator error or a failed practice attempt. These taps come in a cheap plastic bag, which is fine if the product performs accordingly, and it matches the price point. The bits arrived highly magnetized, which caused issues while cutting threads. I repeatedly had to stop and completely clear metal shavings. Even with proper technique (slow speed, straight alignment, appropriate pressure, and avoiding overheating) the tip dulled very quickly, and this is the first use. After drilling through, I attempted to use the base of the bit, which is supposed to function as a countersink. This did not work for me as intended and instead cut into the threads, so I stopped and backed the bit out. While carefully reversing it, the bit snapped. Back to Amazon. I hope this helps. I’d also recommend watching a tutorial on how to properly use this type of bit, especially if you’re new, to avoid unnecessary breakage.

They are tougher than most brands and very sharp

I keep these in my tool box and every now and then they help solve a tricky situation especially with electrical boxes.

Very handy way to retread existing, or new threaded holes
