It is using the drilling of SUS plate, but the carbide of sharpness is excellent.
It is an excellent article on the cost performance.

Used in the machining center.
The cutting edge was hanging when processing 2 items.
Although it did not have any problem with the machining with the high-speed drill, what kind of thing is it with a carbide straight drill ...?

We can not cut anymore from the processing of the second product ...
It is a pity that at this price, there is not such a blade.
I was able to do more when I was using a drill of Rice.

Though it was smaller than I imagined it is handy. After that, how much you have is the point.
I used it to break the keyhole.

I was broken immediately after using it, because the object to be used was bad. Moreover, a broken tip remained in the object, and I felt a lot of trouble.
I used the drill as slow as possible and used while using enough oil, but the tip broke at about 2 cm.
I feel attracted to the word of cemented carbide, but it will be saved if you explain to a certain degree what kind of object to use.
It is not cheap at all, so thank you.

Too bought because it is cheaper than the manufacturer's product too
However, it was too weak for cemented carbide and it was the same as high-speed steel.

It was played with a normal iron drill and I could not drill at all and I tried purchasing it.
A hole opened easily when you tried it immediately.
It's amazing. I will also buy more thick type.

Pilot hole of bolt extractor

It is used for processing the prepared hole of the extractor in order to extract broken bolt.
Inch screw medium strength 3.5φ of this product is used for 5/16 (8 mm). I digged 3 millimeters and the cutting edge broke. We also used tapping oil. Defect quality. I could not even disposable. It is better to buy it directly from China directly at eBay.
