Tap on steel plate
On 2018-02-17 21:52:20
Used for tapping 3 mm screw to 3 mm steel plate.
There is no problem in sharpness, there is nothing of a trimmed, but with the first eclipse
It is repulsed. Because it is M3, it is likely to break if it is impossible with a drilling machine,
I went by hand work.
Tap off the screw hole

Because I was cheap, I was worried that I could break easily, but I could use it just like a maker's item as before. Because it is a hexagon, it will not slip. It can also be used for electric tools, it can be used as a hand-held driver to insert a hexagonal axis, and it can be used manually, which is very convenient. I used it quite a bit, but as of now I have not broken one.

Purchase because it is easy to use and used by other people from before
I tried using it, it was as good as another company's expensive one

Purchased because it is cheap. Iron plate 2.3 mm (pilot hole 4.2) It broke at the sixth time from the new article by M5 thread processing.
Quenching is hard to the center of the tap, the spiral is deep.
Tapping on aluminum frame

I needed a screw hole about 1 cm in length. Whether the fixation of the work is insufficient, the impact driver 's torque setting is not good, or whether I'm clumsy or not, the reason is not somewhat, but it fell into the pilot with a single shot and it broke back and the work became unusable. I broke the broken tap.

Cost performance is the best. I also want to buy it.
Make screw threads on iron materials etc.

It is convenient because it allows you to make screw threads in a short time, it is also cheaper than other companies.
When working jig production
On 2017-04-02 19:47:13
There were variations in the dimensions of the hexagonal axis and it was hard to remove.
I use it where I can not install the nut.

I am satisfied with sharpness well. I am happy if there is also a No. 2 tap.

Also purchased for M5. Since size entry is printing, it disappears soon and it becomes impossible to know whether it is M5 or M6. Although M4 is truly thin, it is distinguished though ....
