Drilling of stainless steel plate and steel material
On 2013-03-16 10:09:33
Although it is cheap, it purchases quite a lot, but I will never last long, I think that it is suitable only for small lot processing, if SS material etc. is good, SUS may be a little impossible, if there is a losing around If you use a bad worker, the blade will fly soon. There are too many eyes, too many? Do not worry about opening a round pipe etc.
Aluminum, perforation to stainless steel for cutting tools before heat treatment
On 2012-02-09 00:00:16
Both aluminum and stain were drilled with cutting oil. Peeling of chips etc. Currently none. However, the weld of the cemented carbide chip is dirty, as it is visually observable as well, the diameter is different by 0.1 mm in the diagonal plane diagonal. I do not mind if it is processing hobby and low diameter of use frequency, but it may be better to stop who uses it at work.
Stainless steel perforation

I can cut it out for reasonable price. There is not much durability. MonotaRO It is a feeling that it is higher durability than a carbide hole saw.

Depending on the shape of the cutting edge, the cut was worse than the domestic production, and the keyy sound was noisy.
Drilling of iron plate
On 2010-06-08 21:23:52
I bought 26 mm and 23 mm at the same time. Although 26 mm has some center blur, sharpness is not bad and it can be used without problems. When 23 millimeters was used for the first time, it got drilled and it was used instead of a drill on hand, when we opened around 4 places, an abnormal noise occurred, and when I confirmed the chip was lacking in some places (it was not dropped out but part was missing ) 1. Neither center has come out 2. I have individual differences as described above (Is there a problem with quality control?) I was able to use it for repairing or remodeling machinery used by myself instead of metal work but somehow I could use it, I think that it is not suitable for professionals.
Drilling of aluminum plate
On 2010-05-10 17:23:26
Although it is good that the drill is pluggable and can be removed, the insertion hole is loose and the drill does not fit in the center, so the center was blurred to the extent that it could be confirmed visually that the core shake appeared. As a cemented carbide hole saw, the price is very cheap so it is reasonable?

Drilling in a comma steel sheet
On 2010-03-21 18:35:51
The price is very cheap and I'm glad but when I cut three places in two places I slip and it will not open again. I am happy if it will cut a little more but I am satisfied if I think that it will cost you. It is a consumable item so it's a satisfying question as it will come soon.

I broke one chip, it was working with a drill machine. I think that sharpness is good. But I do not have to fly chips.
