Sawing plastic – what you'll need to consider
In addition to wood, jigsaws can also cut other materials, for example metal or plastic. In our tutorial, we show you how to cut different plastics with the jigsaw, and explain what you'll need to consider.
Protective clothing and battery removal
You need: Jigsaw, work gloves, safety glasses, ear protectors
It's always important to wear the correct protective clothing when you're doing DIY, and this applies to sawing plastic. Always wear eye and ear protection and protective gloves.
Before you prepare the jigsaw, check our jigsaw blade overview to make sure you're using the right blade. Before you use it, be sure to remove the battery.
Inserting the saw blade
You need: Jigsaw, Jigsaw blade set including jigsaw blade for plastic
It is important to use a special saw blade when sawing plastic. Bosch saw blades for plastic can be identified by their red shank. You will find more detailed information in the saw blade overview. Insert the blade into the jigsaw. Find out how to change saw blades in our guide.
Deactivating pendulum action
You need: Jigsaw
You do not need a saw blade pendulum action for cutting plastic. Plastics vary greatly in terms of hardness and porosity. The additional movement of the pendulum action increases the risk of the cut edge fraying or even tearing. Before sawing, turn the pendulum action switch on the jigsaw to 0 to deactivate this function.
Securing a plastic strip
You need: g-clamps, terry cloth or piece of wood if necessary, Plastic strip
When sawing plastic parts – for example strips – the workpiece must also be clamped securely. Be careful not to scratch the plastic. If you don't have a special workbench with a clamping option like in our example, you can place a piece of terry cloth or wood between the workpiece and ordinary G-clamps. This protects the material.
You need: Jigsaw, Jigsaw blade set, Plastic strip
As soon as you have reinserted the battery, you can start sawing. Place the jigsaw on the workpiece and start it. Important: Never saw too fast, set only a medium stroke rate and apply minimal pressure. The throttle switch should never be fully depressed. Sawing too quickly will cause the plastic to melt. Afterwards, it is worth grinding the saw edge again.
