INFORMATION
The data of the speed tables are guide values. In some cases it may be advantageous to
increase or decrease these values.
When drilling a cooling or lubricating agent should be used.
For stainless materials do not center as the material would compact and the drill bit will become
rapidly blunt.
The workpieces need to be tensed inflexibly and
stably (vice, screw clamp).

WARNING!
For drilling jobs, it is necessary to clamp the workpiece firmly to prevent the bit catching
on the pieces. A machine vice or clamping claws is a suitable clamping device.
Put a wooden or plastic board beneath the workpiece to avoid drilling through to the work table,
vice, etc.
If required, adjust the desired drilling depth by means of the drilling depth stop in order to obtain
a uniform drilling depth.
When working with wood, make sure to use an adequate dust extraction unit, as sawdust can
constitute a health hazard. Wear a suitable dust mask when performing works at which dust is
generated.
