Saw Blade or Circular Saw?

The slitting saw blade is a metal disc or blade with saw teeth on the edge as well as the machines  that causes the disk to spin. It is a tool for cutting metals or other materials and may be hand-held or table-mounted. It can also be used to make narrow slots (dados). Most of these saws are designed with a blade to cut metal but may also be equipped with a blade designed to cut plastic or light metals. There are also purpose-made circular slitting saws specially designed for particular materials. The circular saws are almost exclusively powered by electricity.

Cold saw(ing) machines

Cold saw(ing) machines are circular saws that are used in many metal cutting operations. The saw blades used are quite large in diameter and operate at low rotational speeds, and linear feeds. There are three common types of blades used in circular saws; solid-tooth, segmental tooth, and the carbide inserted-tooth. The circular saw is typically fed into the workpiece horizontally, and as the saw advances into the material, it severs the material by producing narrow slots. The material is usually held in place during the cutting operation by means of a vice.

Typically, the material to be cut is securely clamped or held in a vise, and the saw is advanced slowly across it. In variants such as the saw is fixed and the material to be cut is slowly moved into the slitting saw blade. As each tooth in the blade strikes the material, it makes a small chip. The teeth guide the chip out of the workpiece, preventing it from binding the blade.

  • Cutting is by teeth on the edge of a thin slitting saw blade
  • The cut has narrow kerf  and good surface finish
  • Cuts are straight and relatively accurate
  • The saw shouldn´t leaves burrs on the cut edge
  • Saw setting should be done geometrically.

Saw blades for metal slitting

Blades for metal slitting are almost universally from HSS steel or tungsten carbide tipped (TCT). High speed steel (HSS) blades are mostly available. The saw base can be adjusted for depth of cut. Adjusting the depth of cut helps minimize kickback. The saw base can also be adjusted to tilt up to 50 degrees in relation to the blade.

A cold saw is sawing machine that uses a circular saw blade to cut metal. The name "cold saw" comes from the cutting process they employ. These sawing machines transfer the heat generated by cutting to the chips created by the saw blade. Therefore, the blade and material being cut remain cold, unlike an abrasive, which abrades the metal and creates a great deal of heat in the metal and cutting blade. Cold saws use either a solid High Speed Steel (HSS) or tungsten carbide-tipped, resharpenable circular saw blade.

They are equipped with an electric motor and a gear reduction unit 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. A cold saw cut produces minimal burr, no sparks, no discoloration and no dust. The material being cut must be mechanically clamped to prevent movement during the cutting process. Extra care should be taken to choose the appropriate number of teeth, saw blade type, cutting speed and feed rate. All of these variables are based on the type and size of material being cut. Cold saws are capable of machining most ferrous and non-ferrous alloys. Cold saws are intended to be used with a flood coolant system to keep the saw blade teeth cooled and lubricated.

Cold saw blades

Cold saw blades are circular metal cutting saw blades categorized into two types: solid HSS or tungsten carbide-tipped (TCT). Both types of blades are resharpenable and may be used many times before being discarded. Cold saw blades are used to cut metal
