Pan Head Twist-Drill Screw Thread, Iron / Uni-Chromium M4x13

I bought a lot more cheaper than the home center, it was very helpful!

I can not cut it at all. Drill screws have no meaning if pilot holes are made.

I am extremely satisfied that one thing can be fastened with one electric drill. There is no need to drill a hole under the drill.

I bought three times and the two lots were easy to work with a smooth hole, but there was a screw that one hole did not pierce at all, and there was a feeling that there was losing hitting. However, as I made a chance at the center punch, I had a feeling that there was a smooth hole, so I was satisfied if anything.

I can not say that it will be asked if the cut is good, but I do not think there is such a drill, so I think it is enough.

Will it expire? It is not a good person to ask such a question but it is super expensive, I think that it is good at the neighborhood here because it is expensive. If you use it everyday it's irritating and priced with pride.

There were variations in the products, there was a screw that could not enter at all, with screws going in and out more and more.

I used it to fix the thin iron plate of the storehouse and the angle of the bone. Since the thickness of the angle is about 3 mm, after drilling the hole of 3.5 mm, I screwed the drill screw, but it went well. I will purchase again because it is more convenient to go to buy at a home center.

Dicing is somewhat weak, so it is a consumable item so cheap ones are enough.

I fix it to a 4 mm angle to 3.5 mm hole in the bottom hole, but now three screws made by Hitachi are missing because the screw does not enter with about 30 screws. I opened it with 3 or 3 but I did not enter at all, so I changed it to 3.5. Since the drill is WH14DDL2, is it too strong?
