Alternative to Holesau

Drilling was easier than drilling a hole in a thin steel plate.

Connector processing etc. at wiring work etc.
From Japan

We use a hole saw for drilling into sheet metal, but we use it because the step drill (bamboo shoot drill) is convenient for processing to a resin box and addition to a connector. This time, I bought the type of φ21, φ22 additionally. Although I have not used it yet in full swing, I felt it was sharper than a normal two-blade when I used it for testing.

Sharpness of the tip is not so good, if the tip passes through, it is perfect sharpness, if the tip is out of moonlight, it is perfect.

Pen impact, as the blade of the drilling machine (conventional handler replacement)
From Japan
On 2016-12-17 22:35:56
There seems to be some imported cheapest hundreds of yen now, but in the case of amateur use these things dare to choose the latest one whether it will not be replaced for 10 years. It is not certain whether it is for 4 blades, but I think that I bought a convenient one if I could enlarge the hole lighter than handdermer (for ironworkers).
