[size=+1]METAL-SAW HOLDER
A metal-saw that I have used for a long time has got damaged on the teeth. So I have purchased a new one. Diameter of the new one is 70mm and its inner hole size is 24.5mm. Number of the teeth is 72. Design of the holder is the same as the No.17 holder that I made previously.
