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.

I bought two for a review that I can use normally, but unfortunately I lost it soon. I guess weak weak.
Purchased to enlarge the bore diameter of the burned metal.

While increasing in size by 0.1 mm each before, it was expanded with an ordinary drill blade, but it took time and the drill blade was useless after one use. The carbide drill blade was slightly expensive, but I realized that the effect was satisfactory.

I use it to expand the hole diameter of SUS material, but it is super hard and it is outstanding sharpness. I want to use it again.

There was only cemented carbide, cutting was preeminent.
Longer life, sharpness is also sustained.
Purchase to drill large clip

Because the clip was spring steel, it was unsuitable for the purpose with the chipping of the cutting edge
Repair of heavy equipment

It is a repair shop of a heavy equipment.
I attempted with this monotaro cemented carbide drill so as to drill a broken bolt at the time of disassembling the backhoe traveling motor, but when broke in 2 mm and broke so as to crush it.
I changed it to the cobalt Masami drill I had purchased at the same time without any inquiries, I could drill a hole without any excavation and the difference in the product clearly came out.
I regret that I should have trusted the review of the monotaro hard carbide drill before purchase more.
\ 2581 drill breaks in 2 seconds, and \ 928 drill works in a kitchen work, it is not usually the opposite.
EX with broken stud bolt
On 2017-10-05 14:25:13
The sharpness was preeminent to be surprised. Although it was used for a stud bolt with a burned 6 mm burned in, it was able to be cracked as if cutting aluminum, but ... after penetrating Pakin ... broke. I gave up because the price is price but I want a little more durability.
Steel punch drilling
On 2017-08-02 12:07:44
I expanded the hole of the quenched steel material.
In the review of the other person, durability is a problem, and it is purchased with half duplex.
Taking care of the number of revolutions and feed of the blade, the temperature of the cutting edge, I managed to finish the work somehow.
With the ones on hand, it was saved, although the blade did not stand like a character.
I used it for drilling work ... · · ·.

Because there were no open holes in the baked items, I thought that it was cemented carbide but I thought it was a bit expensive but I bought it. Although drilling itself was okay, I used an adapter to the impact drill and used it, I broke it in the fourth hole. Was not it suitable for impact drill? It was a bit disappointing.
