How to use the adjustable sleeve 1. Hole diameter adjustment when drilling 1. Adjust the scale at the flange periphery of the sleeve to the reference mark (DRV/DRX) or the center of coolant plug (DRZ). (Fig. 1) 2. When making the hole diameter larger, rotate the sleeve in (+) direction and to make it smaller, rotate the sleeve in (-) direction.

3. When rotating the sleeve, insert the wrench supplied with the drill into the hole on the flange periphery to rotate the sleeve. 4. Using the bottom screw of the side-lock arbor, firmly tighten on the drill directly through the sleeve's window. The upper screw should be tightened slightly so that the sleeve will not be damaged. Caution:

• Not applicable for collet chuck type arbor.
• Scale on the sleeve is the reference value. Upper screw (Tighten slightly)

Bottom screw Check the actual hole diameter after adjusting. (Tighten firmly) Scale for milling machines

X-axis of the 2. Center-height adjustment for lathes M achine Most lathe problem occur due to center height deviation. The center height is appropriate if a core approximately 0.5mm diameter remains at the center of the end face. (Fig. 3) Center-height adjustment is necessary for the case as follows: Core

No core remains or core diameter is more than 1mm Fig. 3 Fig. 4

1. Align the drill with the outer insert face parallel to the x-axis of the tool turret. (Fig. 4) 2. Adjust the scale at the flange periphery of the sleeve to the reference mark (DRV/DRX) or the center of coolant plug (DRZ). 3. When no core remains, rotate the sleeve to (+) direction to make the core larger, and when the core diameter is 1mm or more, rotate the sleeve to (-) direction to make the core smaller.

4. When rotating the sleeve, insert the wrench supplied with the drill into the hole on the flange periphery to rotate the sleeve. 5. After completing the adjustment, firmly tighten on the drill directly through the sleeve's window. Note: depending on amount of the center height adjustment, the hole diameter may change. It is recommended that the hole diameter is checked after the center height adjustment.
