OPERATING INSTRUCTIONS
Mounting the dry core drill
Caution: Ensure that the threads of the spindle and the core drill and/or bayonet
connection are matching. Attempting to mount mismatched threads will result in damage
to both threads.
Ensure that the core drill thread and spindle are clean. Any debris could cause
excessive run-out of the mounted core drill. Excessive run-out can cause premature
failure of the core drill and/or safety hazard.
Tighten the core drill to the spindle using two wrenches. Only use correct sized
wrenches to avoid damage to the spindle or core drill connection.
Choosing the correct core drill for the job
Only diamond core drills for dry use are suitable on the SD 17P used with or without soft
impact function.
Special instructions for dry drilling operation
Unlike wet drilling which is a grinding process, a lot of down force is required on the drill,
Dry drilling is a process where the material is cut off. When dry drilling, where the drill
must be able to drill the hole at their own pace, less pressure should be applied on
the drill.
Dry drilling is normally done in softer materials. Note that in very hard materials it may
not be possible to drill dry.
Selecting speeds
There are two speeds to suit the bit size and work piece hardness. Choose the slowest
speed for large diameter core drills and hard materials. If during drilling the core drill
stalls repeatedly, then you should change to the lowest gear. If you are already in the
lowest gear and the drill stalls repeatedly, then you are using the tool over its maximum
capacity.
Caution: Never attempt to change
gears on a running machine!
Only adjust when the
machine is at rest.
