I use it attached to an electric drill.
Do not forget to add drilling oil and use it for long lasting.

There is no problem. In addition, I will purchase it if necessary.
Tapped hole of control board inner plate

I used OSG, but this tap is not usable because it can break easily as it is caught. I should worry about pilot holes from 3.3 to 3.4, but I am worried because there is only 1.6 steel plate. I bought some but the others were the same. In the case of OSG, there is no such thing.

During small-diameter screw standing work, I often taste the tears of tap breaking. For inexperienced metalworking, the low price of this product is the salvation at least.
When tapping products

Although it seems to be somewhat impossible to cut, price is a little cheap, so well, COSPA is subtle.

I broke up during work the other day and got it by supplement.
Tap cutting of woodworking

For this size, if it is hard wood, you can make a firm tap with wood. You can save the ogre if it is an application that does not require drawing power.

Tap work can be done normally. Although it is a consumable item, we will decide on durability from now.
Tap of steel material.

It is good for SS and SK material, but there are some durability when it is hard material such as SKD, DC 53 etc. Because other taps are so, I will only do this review.
Plain penetration tap up to t12 mm

With a radial board, I think that it is very good if it is up to 12 mm with plain board, I broke it if it was t25, I use it properly.
