Please specify the length when ordering. e.g. For ø60 mm drill diameter / 1070 mm drill outer tube length: OT13X1070 Please choose the inner tube length according to the guide below: tool diameter: ø18.40 - ø65.00 mm (OT00 - OT13) ............ 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

| L3 = | Bar rest length | Li = Lo + L6 |
L4 = Length of outer tube in connector* L5 = Length from drill tube tip and peripheral edge tip DTC L4* L6**
L6 = Difference between outer tube length and
inner tube length** DTC 4R (OT00 - OT13) 120 30
(mm) To facilitate a smooth drill entry into the workpiece, make sure that the drill is inside the guiding bush or pilot hole all the way up to 5 mm over the outer tube before starting the drilling. Reference pages: Drill head → 15 (ETU)
