8-6. Drill Bits
The chuck section is designed exclusively for the popular and widely available SDS-plus shank bits, as shown in
Fig. 7. Rotating torque is transmitted to the drill bit by two key rails provided in the tool holding section. A steel
ball is used to prevent the bit from falling out.

The service life of a drill bit with a diameter of 8 mm is approximately 300 holes when drilling into concrete with a
depth of 30 mm. If reground before the end of its service life, the drill bit will continue to provide efficient drilling.
