Such as the drilling of carbon

Carbon I was glad I shaved crispy.
I wanted to use even in the plastic parts, but did not use a shorter overall length. Overall length is happy when there is a thing of about 80mm Toka 90mm. Shank diameter is the same as the blade diameter.

Drilling of carbon plate

Drilling into cast iron, single pipe pipe with hand drill
On 2013-02-14 18:13:47
I immediately lost the cutting edge, but I could use it afterwards. However, asymmetrically lacking will result in vibrations in the rotation and no decent hole. Unilateral pipes could not be easily cut unless you put force in, but if you press oil until the smoke comes out, it will shave out suddenly. I also tried a similar Sumitomo Electric hard carbide drill but it was broken with a single shot. I think that this one is better.
