Because the cutting edge is sharp, the biting was strong and lacked with the first one.

There is no problem with sharpness against aluminum. Cost performance is good. In the case of no punch striking, the first slit may swing and enter diagonally. Since rigidity is weak, it enters obliquely during cutting of aluminum, so it is necessary to remove cutting powder and pay attention to feed amount.

The hole with respect to the description size is 5/100 or more smaller The shaft does not enter, without the pilot hole it is crawling and the accuracy of the product can not be obtained It means that the center has not come out. Easy drilling is fine but care must be taken for items requiring precision.

Extra Masamune Drill It was able to drill a straight hole without stress with a hole of 1.5 mm in diameter and 18 mm in depth. The workpiece is S45C. Processing condition was 1800 rpm 15 mm / min. Cutting oil was dropped into the processing hole every 5 mm of depth using cutting oil containing nano-ink. There was no blur at the moment when the cutting edge hits the workpiece, and furthermore, it was cut well with the thrusul.
