Used for tapping of hardened bolt
On 2017-04-08 17:17:37
I bought it by being advised by a friend, but just by placing an overload on what I want to open a little, I can easily take a tip of the drill and make a hole. And it is not surprising that the facets coming straight out cleanly come out - really can not think of anything other than this drill. I also want a set of long type.

I bought it when I saw friends easily drilling on a thick stainless steel plate. I am using only one but it cuts better than cheap drills.

The sharpness which I have never seen, I was surprised, the price was worth the price.

Certainly the sharpness at first was good, but if you raise the revolution number a little, it will be quick to get out of Namet. It will be easy to break down, and those who used the NACHI iron drill sharpened and used themselves will be able to endure long and last longer. After all it was a cheap item. It is not suitable for professionals to drill in somewhere. By the way, on 3 mm thick plate of SUS 304, only 3 holes at Φ 3. 3 and 2 holes at Φ 6. While the right angle was out in the drilling machine, it was pretty broken, but a pilot hole is necessary. With a hand drill it quickly gets snagged. Thinning at the tip was also done in the easiest way, and it does not apply to the carbide drill after all. I probably will not buy it. You can get angry at the company if you use this.

It was surprising that it was possible to drill very easily in 10 mm thick SUS 304 which teeth did not stand even if using drills of various manufacturers until now! The tool used is a small milling machine rather than an electric drill used in the demo video, but it is lightly pushed down the lever about 30 seconds. A superb drill penetrated the 10 mm thick stainless steel plate which was impregnable. It was the moment I realized that amateurs were able to handle stainless steel which I had given up so far. Respect from the heart to the development staff who commercialized this product!

It was sharpness as reputed. It is outstanding quality. It was still better if the price was a bit cheaper.
