Pliers Stud
CAUTION
This trimmer is specially designed for Studs Cutter.
The flange on studs cut with a hacksaw or disc
grinder is too large for this trimmer so that the
trimmer does not rotate and it is not possible to
remove flange.
CUTTER LIFE AND REPLACEMENT
1. Cutter life
As is shown in Fig. 11, repeated cutting can cause
breaking and warping of the cutter edge. Using the
cutter in this condition can produce flange on the
cutting location of the studs so that the threads are
distorted. This will prevent clean cuts and make it
impossible to insert the nut.
Breaking
As is shown in Fig. 12, the edge is found on four
locations on the cutter. Use the method described
below to change the attachment direction of the
cutter to allow a total of four usages.
If the nut does not fit on the screw due to breaking
and warping of the edge, change the cutter
attachment direction to use the edge without
breaking and warping or replace with a new cutter.
