I like that it doesn't have a flange.
I purchased this product to drill a penetrating hole in a steel pipe.
It is a very common Hole saw.
Originally designed for electric drills, we wanted to drill perpendicularly to the pipe, so we used a ball machine.
As stated in the description, the absence of a flange allows the Penetrating hole to be drilled at 20mm.
Drillable plate thickness:general steel (iron) 3.I was honestly worried about drilling a hole in a 2mm Pipe, but I was able to drill a 2.3mm thick Pipe without any problems.
Naturally, the teeth are not as sharp as the Drill bit, so we applied cutting oil and worked with great care to prevent them from getting stuck.
At first, we did it in such a way that the components were fixed by hand, so we lost the hooking and became a field cat project.
Secure it firmly to the Work.
The hole I drilled was unexpectedly beautiful.
In this case, we used it to weld a 20mm diameter round boss to a steel pipe, but since other sizes are also available in the lineup, it may be used for right-angle butt joints between pipes.
