Jig saws

Jigsaws are used for cutting metal, wooden or plastic elements. They operate due to reciprocating movements of a built-in blade. Particularly, they are used for repairs at the car service station for sawing work pieces, including ones of unusual sizes.

Types of jigsaws

By operation principle:

• Manual. They are driven by mechanical force of a user. The construction has the U-shaped frame, which allows to perform deep cut. It can be made of aluminium, steel or titanium. The aluminium tool has a small weight and low price, but often bends during cutting. Titanium and steel tools are reliable and do not deform during the work.
• Power. They operate with help of built-in motor. The are suitable for both straight and curved sawing. They are highly efficient. In catalogues you can find tools that work from electric main of from battery. The first ones are perfect for continuous works, while the second are portable.

The power devices also differ by the following main parameters:

• Output. The lower this value is, the cheaper the tool is. For instance, one can select the model, for which this parameter is 300 or 900W. High-power equipment allows continuous work for a long time.
• Stroke frequency. Speed of work directly depends on it. Tools with 2500–3200 rpm stroke frequency are popular.
• Depth of cut. For instance, you can buy online the tool which is able to saw a wooden element with the thickness up to 70 mm and metal – up to 4 mm. There are also tools for wood pieces of more than 100 mm thickness.
• Presence of a handle. Some tools are held by the body of the jigsaw itself, the turn-on button is located on it. Others are held by the handle, which is above the functional element.
