PROPRIETATES

1. Terebrae gradariae aptae sunt ad perforandum et amplificandum plura foramina in tenuibus sectionibus laminarum metallicarum, tuborum, plexiglas, materiarum plasticarum, ligni usque ad crassitudinem 5mm.
2. Cuspis cuspis fissurae 135°: celeritatem secandi auget cum autocentratione et terebrae non a centro currunt.
3. Varia diametrorum foraminum uno tantum instrumento perforari possunt.
4. Dimensio foraminis perforati exacta est.
5. Designatio duarum canaliculorum: vitam longiorem et meliorem ablationem fragmentorum praebet.
6. Sulcus Spiralis: melius creat, minus strepitus, minus vis adhibenda est.
