Acrylic lens mounting hole perforation

I used it to drill a hole in the side of a columnar easily crackable acrylic. It worked with a drilling machine because the shape of the cutting edge is good, but it was able to process beautifully without being displaced or muffled.

At the time of counterbore processing, there is designation of guide dust on customer condition. I bought it for 8.5 mm designation this time. You can cut well. It is very convenient.
I purchased a surfboard because I want to make a bolt head of the fin bolt.

I am very happy about the product. I made a perfect milling process. If possible, the shank is quite short so I'd like a length of about 3 cm or so · · · (There seems to be some things in the shank)

Counterbore could be processed beautifully, but the drill felt like it was not good to cut it. It might be better to use the drill as much as a guide.

I can cut it well as usual. If you use it badly, you can easily break the thin dirt.
