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 ...
Morrill-style saw set. A saw set is a tool or part of the tool kit for tuning saw blades. It adjusts the set, or distance the saw tooth is bent away from the saw blade.The magnitude of set determines the cut width and prevents the blade of the saw from binding in the wood.
A dado set or dado blade is a type of circular saw blade, typically used with a table saw or radial arm saw, which is used to cut dadoes or grooves in woodworking. [1] There are two common kinds of dado sets, stacked dado set and wobble blade. Stacked dado set consists of two circular saw blades fixed on either side of a set of removable chippers.
This kind of saw is now usually called a scroll saw. The modern portable jigsaw, with a rigid blade secured at one end and cutting on the up-stroke, was introduced in 1947 by Scintilla AG (later acquired by Bosch). [2] A jigsaw power tool is made up of an electric motor and a reciprocating saw blade.
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.
Cold saw blades are used to cut metal using a relatively slow rotational speed, usually less than 5000 surface feet per minute (SFM) (25 m/s), and a high chip load per tooth, usually between .001"–.003" (0.025–0.08 mm) per tooth. These blades are driven by a high power motor and high-torque gear reduction unit or an AC vector drive.
The blade is made of non-rustproof carbon steel, blue-plastered by hand and finely forged from the base to the tip of the knife. The 90 mm (3.5 in) long blade shows patina (dark spots) caused by decades of use. It can easily be sharpened to a shaving sharp edge. Carbon steel is a popular choice for rough-use knives and cheaper options.
The saw blade for this type of saw enters vertically into the material. These saws are often used as layer saws, whereby a multitude of tubes, profiles, or bars can be simultaneously cut horizontally. In 1974, the first carbide saw with a vertical slide was developed by Arno Willemeit, the co-inventor of the Braunschweig tooth geometry. [5]
