Production of radio control products

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.

I'm better off than I used before. Even if you do not use much force, you can easily open holes.

Cross thinning is very useful for things that can not do punch work because it is very sticky.
Working with general-purpose milling machine

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.
