Use of Drill

• The short cannulated drill (119522ND) attached on the quick coupling (129710ND) is used to prepare the location of the screw head. The protective sleeve (119501ND) must be used during this stage.
• The short drill will be inserted in the sleeve before drilling. This allows to limit the depth of reaming due to marks on the drill.
• When the drill is used perpendicular to the bone, the mark 90° must be flush to the extremity of the sleeve
• When the drill has a 45° angulation, the mark 45° will be aligned with the extremity of the sleeve
• It is only when there is a 30° orientation that the drill will be fully engaged in the protection sleeve
• This allows for reaming only to a depth of 5 mm sufficient to prepare the location of the screw head

• For each of the screw sizes - unless a mono-cortical fixation is required, the cannulated drill (119515ND) is used to finalize the preparation stage
• The drill is introduced over the pin and drilled to a depth that corresponds to the length of the screw to be implanted

Caution: Drills should never be used without the matching pin
