There are many types of saws and one of them is the cold saw. This saw has a circular blade which is used to cut metal. It is known as cold saw because it does not create any heat while cutting as it happens with abrasive saws. The reason being different methods used by the two saws. The abrasive saw creates heat in the cutting blade and the metal while it abrades the metal. On the other hand the heat generated by cutting is transferred by the sawing machines to the chips which the saw blade creates. There are two kinds of saw blades, tungsten carbide-tipped (HSS) and high speed steel (HSS) circular saw blades that can be re-sharpened. This means that these blades can be reused many a times. These blades are driven by a high torque gear as well as a high power motor. The rotational speed used by cold saw blades is very slow as in 5000 SFM and the chip load is between .001” -.003” per tooth.

When the cutting process is going on, the teeth releases the metal in a shearing action and the feed mechanism moves the blade frontward while the blade rotates. While in case of Tungsten carbide tipped (TCT), the body is made of alloy steel and the tips of the teeth are inserted by tungsten carbide brazed. The tangential as well as radial clearance is created by grounding the tips on all the surfaces. For making the alloy bode of this blade wear resistant material like chrome vanadium steel is used which is treated for heat at 38/42 HRC. The Saw Blade Manufacturer make the HSS blade from M35 or M2 tool steel, where in cobalt is used as the alloy. For ferrous cutting the HSS saw blades are treated with heat as well as hardening is done at 64/65 HRC. While for non ferrous cutting applications the same is around 58/60 HRC.

The saw manufacturers make the HSS blade from M35 or M2 tool steel, where in cobalt is used as the alloy. For ferrous cutting the HSS saw blades are treated with heat as well as hardening is done at 64/65 HRC. While for non ferrous cutting applications the same is around 58/60 HRC. There is no production or emission of burr, discoloration, dust or sparks with cold saw blades. Though there are few points that have to be kept in mind while using a saw blade. The type of saw blade to be used depends upon the type and size of the material that is to be cut. Even the number of teeth, feed rate and cutting speed have to be taken into account.
