9 – Maintenance Control List
Safe type tap holders are produced separately for each metric tooth and they have a torque-adjusted
system inside of them. This system is adjusted by producing company according to torque values which
prevent breakage of tap you use, and prevents being exposed to too much force. It reduces tap breakage
risk to minimum. If the hole you use for tapping is a blind hole and if tap reached to bottom or if tap cannot
move because of the jamming of burr created during tapping process or similar reasons, this torque-
adjusted safe tap holder will become activated and even if you continue working for tapping, the machine's
spindle will turn but will not rotate the tap and tap will not move. So that tap breakage risk will be reduced
to minimum. Also decay of tapped part and tap tool costs will be minimum.
According to variety of the tap you use and the hardness of part for which you are carrying out tapping,
torque values of tap holders can be adjusted manually. Torque hardness of safe tap holder can be
increased or reduced. If your tap breaks before tap holder is activated remove wire segment at the front
side of tap holder (See Picture 8) as seen in the picture, rotate interior hub of holder one grade in counter-
clockwise direction in such a way to fit wire segment entrance holes on the hub, and place wire segment
again to its place. In that way torque value of your tap holder will be reduced and your tap will not break
with the activation of safe torque system before your tap
breaks. To operate safe torque system at later and higher torque values, apply the above mentioned
process by rotating clockwise. In that way torque value of tap will be increased and torque system will be
activated later.
WARNING! Attention must be paid at this process because the breakage risk of tap will increase as it will be
exposed to bigger force
