Inserting the router bit (see figure A)

Router bits are available in a wide variety of designs and qualities depending on the intended application.

Router bits made of high-performance high-speed steel (HSS) are suited to machining soft materials such as softwood and plastic.

Router bits with carbide tips are especially suitable for hard and abrasive materials such as hardwood and aluminium.

Original router bits from the extensive range of Bosch accessories are available from your specialist dealer.

Only use undamaged and clean router bits.

Use router bits with a shank diameter of 12 mm wherever possible.

The router bit can be changed when the routing motor is mounted in the plunge base/non-plunge base. However, it is recommended to change the tool with the routing motor dismounted.

• Remove the routing motor from the plunge base/non-plunge base.
• Press and hold the spindle lock button (2) (➊). If required, turn the spindle by hand until the locking mechanism engages.
  Actuate the spindle lock button (2) only when at a standstill.
• Alternatively, you can lock the spindle with an additional open-ended spanner.
• Loosen the cap nut (22) with the open-ended spanner (21) (width across flats 17 mm and 24 mm) by turning it anticlockwise (➋).
• Slide the router bit into the collet. The shank of the router bit must be immersed at least 20 mm into the collet.
• Tighten the cap nut (22) with the open-ended spanner (21) (width across flats 17 mm and 24 mm) by turning it clockwise. Release the spindle lock button (2) or remove the additional open-ended spanner.
