Drilling hole for sash wiring
On 2016-12-13 14:51:01
Although it was used for drilling in a bag-shaped aluminum sash, penetration from the front side was no problem but when trying to penetrate as it was hard to cut. I think that sharpness itself is no problem. It is convenient because it can be mounted on impact drills etc.

It is necessary to cut out about 32 mm in order to release fuel from aluminum cans successfully. For hollowing out aluminum cans, manufacturers responded that they do not need cutting oil. In order to round out using the bottom of the can of beer cans, hole saw is a necessity. Without cutting oil, you can snap out quickly. The finish is also beautiful. I will make many alcohol stove products from now on. It is fun every day.
Production of vacuum tube amp

I used a thin-edged hole saw for the first time. I purchased 24 mm and drilled a hole with a drilling machine. I thought that a hole of 24 mm would be empty, but in fact the hole of 24.4 mm opened. When examining the outer periphery of the teeth with calipers, there are variations from a minimum of 23.8 mm to a maximum of 24.3 mm. I bought a thin-type hole saw for the first time, is it such a thing? Because it was not necessary where tight dimensions are needed, I think I will keep using it, but maybe it will be a little bigger? It may be better to think.
