It results in eliminatingtroubles caused by improper cutting-edge height.

Especially in turning, testmachining is recommended as the drilling diameter will vary Secure the drill by screw A. according to theadjustment. Secure the EZ sleeve by lightly tightening screw B. • Can not be used for collect chuck holders. Tighten screw B only lightly otherwise EZ sleeve can bedamaged! • Over L/D 4 or bigger adjustment, please reduce feed.• For smaller adjustment, the drill itself will interfere with the holediameter. It is recommended that hole diameter should be adjusted to a larger diameter than the drill diameter. J076 www.tungaloy.com +0.2+0.4 X-maxaischoifne
