For replenishment of set items

I bought it for replenishment when I lost the drill blade of a set item or when it broke. This is enough for light work.
Deep drilling in stainless steel
On 2018-07-05 15:03:48
After all, it was a dedicated drill φ10 depth 100 mm 5 holes were opened in 20 minutes. With ordinary high-speed steel, one hole could hardly barely open the next hole with holes.
I would like to use it for the pilot hole of the tap

I do not want Φ 11 for M12 × 1 tap. It is disappointing thought that I wanted affordable because it does not use it only once. I will purchase it elsewhere.
Drilling of metal

It is more sharp than I expected, and I can work without stress.
If prices are cheaper a little more, it is easier to purchase.
To widen the hole

It was used to spread 3 mm of stainless steel to 5 mm. As a result of using 2 pieces, the durability is bad for both of them.
Drilling of stainless steel casting

Sharpness is good, you can use it normally. I do not know about durability yet.
Bumper drilling work etc.

Since it is a normal drill, the feeling of use is normal. It is saying that it is neither possible nor impossible.
Drilling of stainless steel pipe
On 2018-04-16 23:27:26
We made a hole in 3.5 mm thick stainless steel, but it was a very good sharpness until about thirty. I thought it was a normal sharpness from about 30 to 120 pieces. After that I could not gradually break, but in the end I was able to empty about 200 pieces. I was satisfied because I did not think that it was so durable.

I bought it because it is a suspect who is selling to a home center as soon as it gets stuck.
It is good for now
Stainless steel hole work

I use it in the hole of stainless steel It is less cutting resistance with less cutting resistance even with a deep hole Even if the hardening hardness is stiff, it will break if it gets stiff But this one may be less curved?
