THE HACKSAW

THE HACKSAW

 The hacksaw is used to cut steel and other metal.Blades are supplied in two lengths, 250mm and 300mm.

 Two types of hacksaw blade are generally available. High Carbon Steel blades are used for general cutting/sawing. They do not last as long a High Speed Steel blades.

One hand holds the hacksaw handle. Notice how the index finger is used to support the handle and also points in the direction of cutting.

The other hand holds the frame, near the wing nut. Cutting/sawing should be carried out close to the jaws of the vice. This ensures that the metal does not flex or bend under the force of the hacksaw and the sawing motion.
