Abstract

PURPOSE:To cut round bars, pipes, etc. efficiently with a saw without bending or sideway swing in the saw even if it is thin, by providing saw teeth in the inner circle of a doughnut shaped saw body and providing a tension attaching section in its periphery. CONSTITUTION:Internally toothed cold saw 1 is shaped like doughnut and provided with a tooth section on its inner brim, and has a plural number of through-holes 3 in its outer periphery. The holder 6 has at its end face mounting holes 8 with diameter larger than that of the through-holes 3 and in the same number as those through-holes 3. The saw 1 is placed against the end face 7 and holes 3 and 8 are matched. The taper pins 12 are pushed through the holes 3 and 8, and nuts 10 with a flange 13 are tightened to give tension to the saw 1 towards the outer periphery all the time.
