REAMAX TS – Assembly and operating instructions

Assembly instructions for REAMAX TS

When removing the reaming head (1), the jaws (2) can be used to push it out of position, making it easier to remove from the holder. Use key (3) to open jaws (2), but do not fully release, and remove reaming head (1).

Use key (3) to open jaws (2), but do not fully release, and insert reaming head (1).

Use the key (3) to close the jaws (2), observe the recommended tightening torque. When inserting the reaming head (1), this is pulled into its final position when the jaws (2) are closed.

Adjustment for wear compensation: the smallest bore tolerances up to IT 4 can be achieved through adjustment with the hex key (4).

Clean the Morse taper adapter/face contact → grease-free.
Screw the pull stud (5) into the reaming head and tighten using the open-ended spanner (6).

Operating instructions for REAMAX TS

Aligning the DAH Zero holder

The tool is recommended for radial alignment of max. 20 µm.

  1. Loosen all adjustment screws and pre-load with 1 Nm (new tools are supplied in this condition).
  2. Place dial gauge with µm display on the ground bezel diameter.
  3. Turn the tool to determine the point with the largest runout error using the dial gauge.
  4. Adjust the corresponding adjustment screw with the hex key clockwise (1) until half the runout error has been corrected. In doing so, over-tighten by approx. 5 µm.
  5. Release the opposite adjustment screw (2) by the over-tightened amount.
  6. Adjust all 4 adjustment screws until the runout is < 2 µm.

Please note:

  • The runout must be checked and if necessary re-aligned after an adapter changeover, change of application, after any adjustment for wear compensation and before every re-commissioning, using adjustment steps 1 to 6
  • Adjustment screws must always be tightened during usage with at least 1 Nm 
  • The max. re-adjustment torque is 4.5 Nm


  • Uneven angle distribution!
  • There are 2 cutting edges 180° opposite each other = measuring teeth
  • Measure the diameter at the front on the cutting edge (due to back taper, see diagram)
