Electrical construction work

It is difficult to take the iron plate in the inside after using Holsau.
So is not it?
Drilling a slightly thicker steel plate

This type of thin blades are less resistant and can be handy since you can drill a 3-4 mm iron plate if you advance little by little, while oiling, with little oil.
Aluminum plate drilling

The cutter is eccentric with respect to the center drill, and it is not usable. I used it for testing but it is for 27 mm, the hole diameter will be 28 mm. I applied for the return procedure. It is a terrible level that noticed eccentricity just by idling on the drill.
When drilling into iron distribution board

The shaft broke soon. The blade can not be used because the axis broke even though it can cut still more.
For air filter drilling

Because it is thin, depending on the application, it seems to be convenient to use.
Used to process additional holes of BOX

It is used for hole processing of control board and relay BOX. It is re-purchase.
In the past I was using carbide chip things, but I was looking for sharp items to use charging impact drivers, charging driver drills etc.
Using carbide tip type, bimetallic type few teeth, bimetal type large number of teeth (this type), it is sharp and rich is also good. It is not inferior to other manufacturer's products.
Because continuous heating is concerned about heating, there are things that do more than 10 consecutive machining while replacing 2 to 3 pieces, but there is no problem.
If you use it on a thick steel plate that has a thickness of 5 mm or more, the tooth will be gone, but if you do not mistake the place to use it has quite a bit.
The carbide chip type is noticeable if it lends to others, damage of the chip is conspicuous, but this product seems to be less damaged.
With several pieces of machining, machining time becomes short with high speed rotation, and the cuts seem to have less burrs than others. It seems that burrs are further reduced if it rotates at low speed.
Even my colleagues will come up well if it makes a hole easier than a carbide type. I am using the same size difference.
Drilling to pass wiring through aluminum

Excellent sharpness because the blade is thin. It was quite long lasting. After that I want you to increase the type with a little more depth than the diameter 12.
Angle when drilling

Too much wasting (^ ^ ;;
And it is hard to put in bit (* _ *)

Although it can not be helped sharpness becomes worse if it is used several times, it is earlier when the sharpness becomes worse when compared with the commercial item.
When drilling a box

It is very sharp. In the case of plastic, the material hollowed out in the hall remained, but when I used cutting oil, it got cleanly dislocated.
