Saws are edge cutting tools using hardened teeth on the edges of flat metal or a disk or a thin band The size and material of the teeth will depend on the material to be cut and its thickness - thin material requires smaller teeth, soft material requires larger to remove the chips Hand saws include hack saws for metal and coping, cross cut, rip and mitering saws for wood Power saws include circular (round blade) for wood, glass, tile, and masonry, band (long thin loop) for wood and metal A circular saw may be hand held, mounted in a moveable head (chop saw) or mounted beneath a flat surface in a way that lets the blade be adjust up or down or angled (table saw) A band saw may be fixed upright, usually with a tiltable table or may be pivoted to permit the blade to move through the material gripped in a vise
RADIAL ARM SAWS A radial arm saw uses a circular saw, but instead of feeding the material into the blade, the item to be cut remains stationary and the saw travels through the cut, pulled across the track on the radial arm
