BOSCH GST18V-95B 18v Jigsaw BODY ONLY

Cordless Jigsaws are great when you need to make detailed or specific cuts in wood, but need to be mobile or don’t have easy access to a power source. When choosing a Cordless Jigsaw, consider what you’ll be using it for. A good rule of thumb is that as the material you’re cutting gets harder and/or thicker, the more power you’ll need. Speed, which is measured either in RPM (rotations per minute) or SPM (strokes per minute), will either be fixed or variable. A fixed speed jigsaw will provide the same level of output at all times, which might not be ideal. Some materials will scorch if cut by a very fast blade, while if you are scrolling as you cut, a slower speed is what you need. Therefore, using a variable speed jigsaw can be very helpful.

Brushed motors use carbon brushes to transfer power from the fixed part of the motor to the rotor. This creates a reliable and relatively inexpensive motor, but brushed motors do require regular maintenance, in order to either clean the brushes or replace them as they wear out. A brushless motor, by contrast, uses a magnet mounted on the rotor to generate the power and electrical switching to perform the function carried out by the brushes. The additional complexity of the motor’s working means that brushless motors are usually more expensive than brushed.
However, eliminating the brushes also eliminates internal friction and maintenance, meaning that brushless motors offer both increased power and a longer working life. Brushless motors also generate less heat and noise and so, on balance, are considered superior to brushed motors.

Our range of Cordless Jigsaws starts with 12v machines, but the increased power and relative affordability of 18v tools means this has become the industry standard, particularly as the 18v machines offer much more power without a huge increase in tool size.
