The thrusting is made with the nib surface of the tip on the surface to be cut. Use very low hand pressure, with the tip always in contact against the material to be cut. It is important to make small pendulum or oscillation movements while it cuts, because it increases the cutting efficiency.
2- PLANNING
To widen the cavity use very low contact pressure with the wall to be cut, keeping the tip always in contact, but at the same time making some kind of movement, either oscillatory, pendulum, circular, translation or up and down. The best movement is paralel to the surface to be cut to guarantee a very low pressure against the wall. The movement increases the cutting efficiency.
Due to the type of vibration movement the cutting is more efficient in the back and forth direction.
"Thrusting and planning" is more efficient, but, at the criterion of the professional, it is possible to go deepening and extending the cavity at the same time.
The most important is to always keep light pressure with the tip always in contact with the surface and with some type of movement. The continuous movement prevents a single point of contact and liberates the tip to vibrate freely, which increases the cutting efficiency.
