            Cartridge Style Drill Head Diameter Setting

                The drill head diameter is set and inspected with a master insert in our final inspection.
                However, the inserts in the market have a tolerance fluctuation so each time you index
                the insert, the diameter must be adjusted as per the following method.                               DEEP HOLE DRILLING

                Note: When a corner change is made on the insert, it
                must be adjusted to the correct size or damage can
                be caused to the head body or workpiece material.





                                                              1. Remove the inner cartridge to avoid interference
                                                                with the guide screw.




                                                              2. The dimensional guide pad must be slid
                                                                forward to measure the diameter.
                                                               2.1   Loosen the lock screw and slide the guide
                                                                    pad forward.
                                                               2.2   Re-tighten the lock screw at
                                                                    the measuring position.


                                                              3. Measure the diameter with a micrometer.
                                                                We recommend setting the tool diameter at h8
                                                                tolerance to the cutting diameter.
                                                                If the diameter is incorrect, go to step 4 below.
                                                                If it’s correct, go to step 5 below.



                                                              4. Adjust the outer cartridge
                                                               4.1   First loosen the lock screw of the outer cartridge
                                                                    and then tighten it slightly.




                                                               4.2   Proceed to adjust the diameter, using the
                                                                    2 adjustment screws and measure with a
                                                                    micrometer.




                                                               4.3   When set to the size, re-tighten the lock screw.
                                                               4.4   Recheck the diameter with a micrometer.
                                                                    If it is still out of tolerance, repeat the procedure
                                                                    from steps 1-4.
                                                                    Note: Please make sure to tighten the lock screw firmly
                                                                    before use. If loose, the cartridge may move and cause
                                                                    serious problems during machining.


                                                              5. Slide the dimensional guide pad back to the
                                                                original position and tighten the lock screw.


                                                              6. Replace the inner cartridge and tighten the
                                                                lock screw.
                                                                Note: Please check that all lock screws are
                                                                firmly tightened, as they may come loose
                                                                if vibration occurs during drilling.
