Selecting drill chucks and tools
Hammer drilling and chiselling require SDS-plus application
tools that are inserted into the SDS-plus drill chuck.
For drilling without impact in wood, metal, ceramic and
plastic as well as for screwdriving, tools without SDS‑plus
are used (e.g. cylindrical shank drill bits). For these tools, a
keyless chuck or a keyed chuck are required.

(e.g. cylindrical shank drill bits).

Secure the keyed chuck (19) using the securing screw
(18). Note that the securing screw has a left-hand
thread.
