ATORN drill chucks — components and functional principle
① Open the clamping jaws anti-clockwise to insert the respective cutter.
② The cutter must be pushed in all the way to the stop, so that the tool shaft is against the entire
length of the clamping jaws. (Caution: Do not clamp conical shafts, as there is a risk of accident!)
③ Turn the key clockwise to the specified tightening torque, to properly clamp the tool. Extensions
or tightening aids must not be used, as too much tightening torque can break the bevel gear drive.
Here, the pinion serves as a predetermined breaking point to avoid more significant damage to the
drill chuck.
④ Once it has been verified that the cutter is clamped correctly and centred, the drill chuck is ready
for use.
Secure clamping:
All ATORN drill chucks are clamped with a hexagonal cross handle key via a bevel gear drive at the side. The
key is turned clockwise to clamp the drill chuck. The drill chuck is opened in the anti-clockwise direction
(see markings on the pinion bore). Step-by-step instructions can be found in the respective operating
instructions.
Care and maintenance:
ATORN drill chucks are maintenance free. After use, the drill chucks should be wiped with a clean cloth.
Before storing, the drill chucks should be oiled to prevent corrosion.
Caution: Do not use compressed air to clean drill chucks as fine chips can enter the clamping mechanism.
The drill chucks must not be cleaned with solvents or cleaners containing solvents, as these can cause
corrosion.
