scie à métaux -> hacksaw

La scie à métaux est un outil spécialement prévu pour pouvoir scier le métal, mais aussi d'autres matériaux durs. Pour ce faire, cet outil possède une denture très fine et très acérée. Contrairement aux scies à bois, la lame est habituellement accrochée aux deux extrémités pour être bien tendue, afin de faciliter la découpe. La lame est interchangeable car elle s'use plus vite que dans le cas du bois.

A hacksaw is a fine-tooth saw with a blade under tension in a frame, used for cutting materials such as metal or bone. Hand-held hacksaws consist of a metal arch with a handle, usually a pistol grip, with pins for attaching a narrow disposable blade. A screw or other mechanism is used to put the thin blade under tension. The blade can be mounted with the teeth facing toward or away from the handle, resulting in cutting action on either the push or pull stroke. On the push stroke, the arch will flex slightly, decreasing the tension on the blade.

A hand-held saw used for making straight cuts in metal and other hard materials. It consists of a thin blade with very fine teeth held under tension in a steel frame. The teeth can be placed so that they face away from the handle or the opposite way. On the push stroke the arch of the steel frame bends a little releasing the tension on the blade. If the labeled side is placed upward when mounting the blade, the teeth will face the handle resulting in sawing action by pulling. The blade can be turned at a right angle to the frame for long cuts by rotating the bolts in their square holes. It is normally quite brittle and may snap unless care is taken.
