cold-saw

Century Dictionary and Cyclopedia

1. n. A saw for cutting cold metals; especially, a power sawing-machine used in cutting iron beams, rods, rails, etc. Such machines employ heavy circular saws driven at high speeds, the metals to be cut being clamped to a table and fed to the saw. In some machines the saw is fed to the metal. Steel disks driven at very high speeds are also used in place of saws, and are called friction-disks. In some smaller machines band-saws are used. There is also a metal-sawing machine which employs a reciprocating saw resembling a hack-saw. The large machines are also called cold-saw cutting-off machines. See milling saw.
