Dremel scroll saw. A scroll saw is a small electric or pedal-operated saw used to cut intricate curves in wood, metal, or other materials. The fineness of its blade allows it to cut more delicately than a power jigsaw, and more easily than a hand coping saw or fretsaw. Like those tools, it is capable of creating curved cuts with angled edges ...
Although the coping saw is often used for similar work, the fretsaw is capable of much tighter radii and more delicate work. It has a distinctive appearance due to the depth of its frame (typically between 10 and 20 inches (25 and 51 cm)), which together with the relatively short five-inch (13 cm) blade makes this tool appear somewhat out of proportion compared with most other saws.
A hand-held circular saw is the most conventional circular saw. This miter saw is a circular saw mounted to swing to crosscut wood at an angle. A table saw. Tractor-driven circular saw. A circular saw or a buzz saw, is a power-saw using a toothed or abrasive disc or blade to cut different materials using a rotary motion spinning around an arbor.
The coping saw blade is removable by partially unscrewing the handle and can be installed in the frame such that it cuts on either the push stroke (teeth pointing away from the handle) or pull stroke (teeth pointing towards the handle). [4] The blade is prevented from rotating by means of the short steady bar provided where the blade is attached.
The saw blade's teeth are tipped (via welding) with small pieces of sharp tungsten carbide block. This type of blade is also called TCT (Tungsten Carbide-Tipped) saw blade. Carbide-tipped saw blades are widely used to cut wood, plywood, laminated board, plastic, glass, aluminum and some other metals. Solid-carbide saw blades
The most common blade is the 12 inch or 300 mm length. Hacksaw blades have a hole at each end for mounting them in the saw frame and the 12 inch / 300 mm dimension refers to the center to center distance between these mounting holes. [4] The kerf produced by the blades is somewhat wider than the blade thickness due to the set of the teeth.
