Currently used short bit has no top thread, but I think that it is easier to use this without it.

Because it can buy it cheaper than home center, it is saved. Sharpness is no problem.
Wood drilling work

We opened the package and confirmed the cutting edge first, polished on the outside, but we did not know what was caused by polishing inside, but the burr did not become a large blade. We decided to polish the back of the blade here and use it. Firstly, inspection after production is not done! Please make sure you have good products.

Sharpness was bad and I took time. However, because it is one time use, it helped enough. If you have multiple holes, we recommend you to buy better things.

You can drill beautiful holes at high speed with impact. The speed of drilling is surprisingly fast, working efficiency is high.

Although I bought it from a cheapest one, I bought it from a cheapest one, but it is bad, it has burrs on its surface, it is a high level job, so it will not be used. The price is cheaper than the first-class maker, but because it did not become usable, it became high shopping.

Although it is not cheapest, it is the bit that can be most reliable in using it.
Pilot hole for woodworking tapping screws
On 2013-08-07 19:11:09
I bought two, but one of them is not in the center, it is in a state of turning around when turning it by turning it on a drill board. The other one is usable normally. Depending on the characteristics of the product, it often goes into the tree, so if you use it with a rechargeable electric drill, the hole strikes deeply. I think that this is a usage problem, but it is a bit hard to use as a way of using it.
