Hammer Bits
SDS adapter
The SDS adapter is available in various designs for power drills. Made to fit the different bit diameters, there is the most popular SDS-plus adapter with a crosssection of approx. 10 mm and the SDS-max adapter with a cross-section of approx. 18 mm. The SDS adapter general has two functions: Locking: The bit/chisel locks by means of opposite recesses running lengthwise in the tool, into each of which a ball, integrated
in the drill chuck, engages. Torque: The torque is transmitted via grooves in the bit/chisel, in which lengthwise ridges in the drill chuck engage. With axial transmission of the hammer percussion, the balls descend and the ridges slide into the grooves.
Spline
Drills with a spline adapter are also used. These facilitate drill holes within a diameter range of approx. 12 mm to 38 mm.
