Notes
- Minimum Diameter ØD = Ø8.0mm
- Maximum Diameter ØD = Ø22.0mm
- Maximum L/D Ratio = 2.5
- Maximum Length L = 50mm
- Shank Diameter Ød = 25mm

Operating Instructions
- The tool is initially set on zero mark on the scale. (pic 1)
- After clamping the tool in the hydro grip or side-lock adaptor or ER collet chuck adaptor, measure the exact diameter on the pre-setter or by using a precise dial indicator
- In case you wish to adjust the diameter, loosen the Locking Screw of M8 with the provided Allen key of 4mm. (pic 2)
- Use the same allen key to adjust the diameter by using the scale mentioned on the body of the tool. (pic 3)
- The smallest division is the least count of the tool, adjust accordingly and then recheck if the required size is achived. (pic 1)
- If the required diameter is achieved, tighten the locking screw with a torque wrench using a torque of 8 Nm (Recommended) for precise repeatability and to ensure sufficient torque for locking (pic 2)
- The tool is now ready to use.
Precautionary Measures
- Due to constraints in the assembly tolerances, it is recommended that tools, if damaged, are to be returned to Renuka Tools for assessment/repair in a controlled environment. Commercials for repair can only be determined after detailed assessment of the damaged tool.
- Please change the locking screws and insert screws ahead in time to avoid accidents.
- Kindly change the mounting screws and insert screws ahead in time to avoid accidents.
- In case of any observed decrease in accuracy over the time of usage, kindly request Renuka Tools for servicing the tool.
