2C. If using Chuck Type Floating Drill Holder, install drill in chuck and tighten securely with key provided.

Drill should find its own center. While holding pressure of turret against drill, stop spindle rotation, then tighten both body screws securely.

5. Restart spindle and continue drilling hole. Check hole for size, tapers, bellmouth etc. and repeat above operations until hole is as desired.
