5. Tools and accessories
For metal, use only flawless, sharpened drills; for
stone and concrete, only rock drills with hard metal
inserts.
Good results are only achieved with sharp chisels,
therefore sharpen the chiselling tools in due time.
This prolongs the service life of the tools and en-
sures good working performance.
Sharpen chiselling tools with grinding wheels (e.g.
ceramic bonded corundum wheel) with a steady
supply of water. Standard values for this are shown
in the illustrated instructions. Take care that no an-
nealing colouration appears on the cutting edges,
otherwise the hardness of the chiselling tools will
be impaired.
Drill bits with a cylindrical shaft are used for drilling
in metal, wood and plastic. A keyless drill chuck
(max. 13 mm clamping diameter) is available for
this purpose.
The drill chuck is mounted onto the carrier spindle
of the screw adapter
6
or of the device.
All common drill chucks with 1/2" x 20 UNF internal
threads (13 mm max. chuck opening) can be used.
The drill chuck is mounted on the screw adapter
6
(accessories) for screw-bits.
