General purpose lathe drill

There is no problem at all if it is a hole preparation that does not require precision
We used S45C, SUS304, A5052 etc,
You can use chips out well without problem.
It becomes as large as 0.2 hole diameter, it is about 3D ~ 4D
Since up to 0.5 holes are bent,
It can not be used for precision required items.

Although it is the second purchase, I think that NACHI cobalt strain drill type I type is more expensive and shorter in price.

It was supposed to be shipped after 5 days but it took delivery time 3 months after placing an order, so we made it on time with a hand-held item. The sharpness seems to be nice as far as it is tried after arrival, but it is in trouble if you do not get it when you need it.

It is a god that can cut very well. I felt it was expensive but it turned out to be cheap. It's long lasting.

I will do quite a bit of money, but after considering work efficiency it will become moonlight

Special thinning feels liable but it is only a few millimeters of the tip. As I become shorter by sharpening, I feel like it will not change from ordinary drills, but it is still to come. It would be nice if you could throw it away when you can not buy it, but how about using it for a long time?

I think that it is suitable for making holes in metal. It seems not suitable for thin plastic. I think that it is good to drill holes by selecting materials.

There is no need for oil, let's work at low speed. As much as the SUS board becomes a plate chocolate, it gets pickpockets. Become maggie
