Desired = (Drill&+ Increase of JFS) + 0.1mm
(Eg.) Desired diameter is 20.3mm (oversize is taken as 0.1mm).
(Note) Oversize can vary due to the cutting conditions used, please use the above as a guideline.
Oversize can vary due to the cutting conditions used. Therefore it is recommended to purchase as a set.
When placing an order, please use the set order number. (5 sleeves/set)

Insert screws A of the side lock holder directly to the open window of the sleeve and fix the drill. Tighten screw B to a degree so as not to damage the sleeve.
(Note)
• Fine adjustments cannot be made for the diameter
• Cannot be used with collect chuck type holders.
Please ensure the highest rigidity possible exists in both machine set up and workholding.
Refer to the following graph for coolant pressure and volume. Coolant is an important factor in the efficient use of these drills.
Cannot be used for stack drilling. In common with many indexable insert drills, these drills produce a round disc on exit which unless evacuated may cause the drill to fracture.
