It is used for steel plate drilling for metal hardware for big door with outside construction. I made one hole in the test, the sharpness is GOOD but the durability is unknown.

It is possible to drill a lot (500 results) if it works so that it does not knead at right angle to the work material at proper rotation and feed, cutting oil is recommended for center drilling. Considering the overheating of the backing drill for continuous machining, it seems that there is an effect to prevent chip chipping when coming out.

It was about 3 mm iron plate so we could puncture without problems. It's all right with chip.

For drilling a 25 mm thick aluminum case I bought it. The sharpness is also good, and the carbide blade is still good.

It is very easy to drill the work. I do not know the durability yet so I made it "somewhat satisfied".

A2017 I used it to make holes 8 mm thick. Since 8 mm is impossible from one side, it is processed from both sides. It was easy to open.

I bought 48 holes in 2.3 tons of mild steel, but I bought oil so as not to raise the temperature, but when I opened 30 pieces, the super steel could not drill out hole. I think that the life is too short. Even made in China it will not break in dozens of holes.
