Inner tube length = Outer tube length + 30 mm tool diameter: ø65.00 - ø123.99 mm (OT14 - OT20) .......... Inner tube length = Outer tube length + 190 mm tool diameter: ø124.00 - ø183.99 mm (OT21 - OT25) ........ Inner tube length = Outer tube length + 220 mm Tube length for special drills Please use the guide below to calculate the drill tube length.
