2. Reciprocating saw - Wikipedia

   en.wikipedia.org/wiki/Reciprocating_saw

   Reciprocating saws have many uses; here, one is shown cutting through hard-to-remove nails in a staircase. A reciprocating saw is a type of handheld, small, machine-powered saw, in which the cutting action is achieved through a push-and-pull ("reciprocating") or back-and-forth motion of the blade. The original trade name, Sawzall, is often used ...

3. Carbide saw - Wikipedia

   en.wikipedia.org/wiki/Carbide_saw

   The name carbide saw came from the tool, a circular saw blade, with silver soldered carbide tips. It competed with and just about replaced, solid or segmental HSS blades, because carbide is much harder than HSS. Before HSS saws were developed, abrasive, friction or hot saws were used and are still manufactured for certain applications.

4. Cold saw - Wikipedia

   en.wikipedia.org/wiki/Cold_saw

   Cold saw. A cold saw is a circular saw designed to cut metal which uses a toothed blade to transfer the heat generated by cutting to the chips created by the saw blade, allowing both the blade and material being cut to remain cool. [1] This is in contrast to an abrasive saw, which abrades the metal and generates a great deal of heat absorbed by ...

5. Saw - Wikipedia

   en.wikipedia.org/wiki/Saw

   Carbide-tipped saw blades 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 ...

6. Cemented carbide - Wikipedia

   en.wikipedia.org/wiki/Cemented_carbide

   Cemented carbide. Circular saw blade with tungsten-carbide inserts. Cemented carbides are a class of hard materials used extensively for cutting tools, as well as in other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium ...

7. Molybdenum carbide - Wikipedia

   en.wikipedia.org/wiki/Molybdenum_carbide

   Molybdenum carbide. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Molybdenum carbide is an extremely hard, refractory, ceramic material, commercially used in tool bits for cutting tools. There are at least three reported phases of molybdenum carbide: γ- Mo C, β-Mo 2 C, and γ'.
