These tap bits work great for my new home’ project. It makes things faster and more neat outcomes with all the bit sizes. I used it for installing my new storm door, and it was easy.

The quality is very good, completely consistent with the seller's description, very satisfied, really like it, completely beyond expectations, the delivery speed is very fast, the packaging is very careful and strict

So useful!! I have been using the old tap/die tools for as long as I can remember and I hate them... this is a game-changer though! A fraction of the time invested with a better end result. I’m keeping a set of these in my toolbox at all times from here out!

I bought this set for my dad for this repairs collection. He told me that the drills were razor-sharp. Easy to drill into wood and even metal. Nice for the value for this set! Very easy to use just screw it tight and you all set to drill all you want.

These bits are awesome. I bought them because it was a great combination of different sizes. The bits are very strong and I was able to drill tap the aluminum for my workbench project. I would definitely buy from this vendor again. She shipped everything immediately.

I work at an automotive factory and use a drill and tap quite often. I bought these to decrease in time spent on hand tapping. Used them today on 10, 1/4 inch steel brackets and the 5mm drill and tap worked amazingly. No problems at all. Great product.

I have been working with them for 4 months and they're rock solid so far. Been tap-drilling on both steel and aluminum and it's been perfect so far. Just gotta know what you're doing.

Exactly what I needed for a job. I had to do a bunch of repetitive operations and these really helped speed things along. I hate changing tools every few minutes just for a simple job.

So far these seem like well-made bits. I bought this set to drill and tap aluminum extrusions. I have only used the M5 tap but many many times. It is still sharp and cuts very well. I always use aluminum cutting fluid and never let the bit get too hot. With proper use and maintenance, I can see this set lasting a long time.

This set of taps worked great. I liked that they drilled the hole, and tapped it at the same time. All of the tappings were done on aluminum, and they made perfect threads every time. Take your time when using the bits. Use plenty of oil, and take it slow. I had no problems with the set so far. Not a single one has broken yet. I really like them a lot.
