KEY FOR MEASURING HEAD RELEASE TORQUE

The release torque in unclamping a head is measured with a torque driver to determine the body’s tool life. Please refer to the below for the standard release torque value which indicates the end of tool life (The value less than the standard should be judged as the end of tool life).

Head designation	Release torque value to indicate tool replacement (N・m）	（cN・M）
DMP100-109	0.2	20
DMP110-119	0.2	20
DMP120-129	0.25	25
DMP130-139	0.25	25
DMP140-149	0.3	30
DMP150-159	0.3	30
DMP160-169	0.35	35
