DRILLING SPEEDS
The drill speed depends on the diameter. The recommended speed is 800–
300 rpm depending on the drill type (handpiece angle reduction ratio
16:1–20:1).
Article drilling speed (rpm)
Round bur 800
Pilot drill Ø 2.0 mm with/without depth stop 800
Pre-drill Ø 1.7 / 2.8 mm 600
form drill Ø 3.3 mm with/without depth stop 550
form drill cortical bone Ø 3.3 mm** 550
Tap Ø 3.3 mm* max. 15
form drill Ø 3.8 mm with/without depth stop 500
form drill cortical bone Ø 3.8 mm** 500
Tap Ø 3.8 mm* max. 15
form drill Ø 4.3 mm with/without depth stop 400
form drill cortical bone Ø 4.3 mm** 400
Tap Ø 4.3 mm* max. 15
form drill Ø 5.0 mm with/without depth stop 350
form drill cortical bone Ø 5.0 mm** 350
Tap Ø 5.0 mm* max. 15
The lower edge of the depth mark is the reference for the preparation depth.
CAUTION!
The maximum apical extension length of the drill is 0.6 mm.
COOLING
The cooling occur through external irrigation on the angled hand piece with
sterile saline solution (pre-chilled to 5°C/41°f).
DRILL LIFE
Drill longevity depends on bone quality and drilling technique. The pilot
drills, pre-drills, and form drills are good for 10–20 drilling cycles. If excessive
force has to be applied because of a dull drill, then change the drill immediately
to prevent bone overheating.
CONELOG ® SCREW-LINE IMPLANT
The recommended maximum drilling speed for thread tapping is 15 rpm
(handpiece angle reduction ratio 70:1–100:1). The tap adapter for the
torque wrench also permits manual tapping.
* Using the tap is recommended for bone qualities 1 and 2.
** The form drill cortical bone reduces the torque for implant insertion into hard
bone quality 1.
