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 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.
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.

Changing the guide pads
The guide pads can be changed if worn or damaged. When using new guide
pads check these are correctly aligned. ( Setting Guide Pads).
Setting guide pads for through holes:
The bore diameters for the drill heads are quoted
3
for inserts with corner radius of R0.4 mm.
On delivery the guide pads are arranged for
6
use with blind bores and lie a minimum of 0.25
mm below the bore diameter.
For through holes we recommend the use of
our shim sets to adjust the guide pads.
If the overall length (complete tool) exceeds the
measurement range of the presetter, locate drill
head on centering pin
Procedure:
• Measure ACTUAL diameter of drill head with
indexable insert installed (Figure 1).
• Determine diameter of guide pads individually and
adjust to recommended value (Figure 2).
Example:
Drill Head dia. = 35,06 mm
Guide pads dia. = 35,06
Guide pad diameter must be between
34.91 and 34.86 mm.
