Off-Centre Drilling
Thanks to the special design of the holder and the indexable inserts, off-centre drilling is possible.

Application Notes
Mounting of the insert: for tools Ø 8 mm, right-hand or left-hand inserts are required. From Ø 10–32 mm, neutral inserts are applied.
Machining across the centre line: if the machine has insufficient movement across the centre line, the external diameter cannot be machined with the same tool — use a right-hand MultiCut tool instead.
Through hole: with through holes, a sharp-edged disk is created as the tool breaks out. Safety measures are necessary.
Chip booster / coolant pressure (EcoCut, 2.25D range): an innovative bidirectional coolant supply improves chip evacuation, with an additional backwards-directed coolant stream from the flute area. Minimum coolant pressure 1.5–3 bar (optimum 5–7 bar).
Insert Grades
Coated high-performance grades, covering ISO material groups P, M, K, N, and S.
