Fitting central drill bit / indexable inserts 4:
1
• Insert central drill bit 1 in drill head with clamping surface toward clamping
screw 2 and clamp.
• Insert indexable inserts 4 in insert seatings 7 and tighten clamping screw 5
with recommended torque. The bore diameters of the drill heads were produced
for a corner radius of 0.4 mm. Ensure proper seating at contact surface and
circumference when installing indexable insert 4.
• Insert indexable insert seatings 7 in drill head and tighten location screws 8
with recommended torque.
Length adjustment central drill bit 1: In principle there is no need to
adjust the length of the central drill bit (preset at works). However, if an
alternative length setting is required, this can be achieved by applying the
adjusting screw 3 ( table page 20).
Fitting drill head:
• Insert drill head in basic element and measure diameter at outside indexable insert.
• Remove drill head again, turn by 180° and insert in basic element again.
Measure diameter again.
• Production tolerances can result in different diameters. Always select position
with largest measured diameter.
• Screw in both clamping screws 6 and alternately fasten them slightly. Then
tighten with recommended torque.

Set bore diameter:
• The external insert seating can be set 1 mm in the
diameter.
• Loosen the location screw 8 and refasten slightly.
• Using adjusting screw 9 set the required diameter.
• Fully tighten location screw 8.
Setting guide elements (carbide pin):
• Loosen threaded pin k.
• Adjust carbide pin j with key L01 04370 to
diameter (see section).

• Using threaded pin k clamp carbide pin j.
Please note: Before the tool is used, the threaded pin
k must be checked for firm seating due to possible
settling of the copper disc l.
If the overall length (complete tool)
exceeds the measurement range of the
presetter, locate drill head on centering
pin in chuck
A
Procedure:
• Measure ACTUAL diameter of drill head with
indexable insert installed (Figure 1).
• Determine diameter of carbide pins individually
and adjust to recommended value (Figure 2).
Example:
Drill Head dia. = 72.06 mm
Carbide pin dia. = 72.06
Carbide pin diameter must be between
71.91 and 71.81 mm.
Please see notes on safety (page 21)!
