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.

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.
Drilling of super steel parts
On 2017-07-05 23:30:05
Although I tried various drills, I could not drill work, I thought that it would be possible if a super steel steel drill was possible but it was slightly expensive, but I bought one hole opened (not perfectly penetrated) It is regrettable that it will break apart in the middle of the second hole and it will not be used. Is it a Chinese product?
Drilling of steel plate
On 2017-06-30 18:02:02
I arrived today and I pierced the plate with 6 mm thick steel sheet quickly, but I could smoothly drill the 1st piece but the sharpness fell off in the middle of the 2nd sheet, and I started to drill a continuation again As a result, the carbide drill has broken apart. I was disappointed with the product without durability.

Since it arrives immediately after ordering, you can order with confidence at the time of emergency.
Agitator Bearing Horizontal (iron casting) It was used for drilling of a thickness of 6 to 7 mm.

Before the hole opened, a lot of lateral shake broke. Next I made the same hole with the long drill I purchased, but I could open it very smoothly, so the quality may not have been good at first. I expect improvement.
