Properly cutting metal

A locksmith’s hacksaw is a tool most commonly used for cutting section steel, pipes, sheet metal. hacksaws in different lengths are available on the market, the most common is a 300 mm long hacksaw blade.

Then cut a groove, along which the hacksaw blade will advance.

You can also create a groove with a three-edged file. The main thing is that from the beginning the saw should be at right angles. Once the hacksaw enters the metal, it no longer needs to be pressed with.

Guide the hacksaw with both hands: the right hand holds the handle, the left hand is on the frame. Saw with even strokes and firm pressure.

When cutting thin metal sheet, use wooden pads: then the sheet will not vibrate, and the blade will not be jammed.

How to set the blade

In the first case, the blade is stretched between the mounting holes and secured with a wing nut. In the second action is performed similarly, only the saw is put on and removed by means of a special lever, usually located at the edge far from the handle.

Set the blade so that the teeth tilt in the opposite direction to the handle. When the hacksaw works, cutting of a layer of metal will occur during a “pull back” motion. Reverse direction “toward you” is idle, when no cutting of the workpiece takes place. Therefore the efforts of the reverse movement are futile. In addition, it is so easy to blunt the teeth of the blade.

The working body of electric hacksaws is attached differently. For example, below is the process of replacing the blade with a Makita JR 3070 CT sabre saw. To do this, you will need to:

  • remove the blade;
  • place the end of the new saw blade in the slit of the holder until it audibly clicks into place.
