General instructions for use
Using the SIM holders
Insert the MSD supercut drill into any of the Tiny Tools holders and
tighten the two clamping screws on the tool flat (in case of CIM use
the internal tool indexing).
Use the smallest possible tool overhang for maximum tool stability.
Adjust the rear stopper till the front of the screw touches the tool shank.
Non-rotating drill aligning
Drilling operation on lathe is called non-rotating drilling, when the
workpiece rotates instead of the drill. It is extremely important to
ensure the smallest axis misalignment h, as possible, between a
tool and lathe spindle prior machining. Large misalignment could
cause poor quality of holes or even drill breakage, the solid carbide
drills are very sensitive to bending.
To achieve high quality holes and avoid hole shape deviation, a drill
axis must be parallel with the spindle axis.
