Cold saw

[4] They are equipped with an electric motor and often a gear reduction unit[5] to reduce the saw blade's rotational speed while maintaining constant torque.

This allows the HSS saw blade to feed at a constant rate with a very high chip load per tooth.

These blades are driven by a high power motor and high-torque gear reduction unit or an AC vector drive.

They are called "cold saw blades" because they transfer all the energy and heat created during the cutting process to the chip.

In order to produce a high quality HSS cold saw blade, it is necessary to start with very flat and properly tensioned raw material.

Solid HSS cold saw blades may be used for cutting many different shapes and types of metal including: tubes, extrusions, structural sections, billets, bars, ingots, castings, forgings etc.

The alloy body is generally made from a wear-resistant material such as a chrome vanadium steel, heat treated to 38/42 HRC.

Portable cold saws were primarily designed for sheet metal roofers in the building industry,[citation needed] and can cut up to 6 mm (0.24 in) thick mild steel.
