How a Plunge Router Works
A plunge router is a type of router that is placed directly on the face of the work or material being cut, usually wood, metal or plastic. When the motor is turned on the cutter is slowly lowered into the work, cutting into it. To use a plunge router you need to select and insert the right bit and choose a depth.
Choosing and Inserting a Plunge Router Bit
Make sure that you select the right bit before you begin any project using a plunge router, as each bit is capable of offering numerous types of cuts depending on what depth you set. To load the bit depress the spindle lock with the router unplugged. Depending on your particular set up, a special wrench may be needed. It may be necessary to putting the plunge router on its side to insert the right bit.
Choosing a Depth
If you are not sure what depth you want, utilize scrap wood to create the depth that you are looking for. If the router is electric, take care not to plug it in just yet. Release the lever for the stop after loosening the locking bolt, and use the side scale to set your chosen depth stop. To use a plunge router you have to have a pattern to follow, so you may want to clamp a straight board at the appropriate distance for this purpose.
