Oil ring is used to supply coolant through
the drill in rotational applications.
T/C Guides(for through hole)   Sharpening the blades

In case of through hole drilling, the drill may vibrate immediately before breaking through, depending on hole diameter, cutting speed and feed rate, and rigidity of the machine spindle. This can result in damage of the cutting blades. Using T/C guides when boring through holes will minimize vibration and help prevent tool damage.
