Each tool in the Secure Grip range comes
with the appropriate sizes of Collets for
that tool. If the Collet labelling is worn or
missing, then the Collet can be measured
to ensure that the correct size is selected.
An accurate measurement can only be
obtained with the Collet mounted on the
Collet Holder. To do this:
• Remove the Collet Head Assembly from
the tool and disassemble (see Section
5.4 for details)
• Slide the Collet over the Collet Holder
• Measure the centre section of the Collet
with the vernier calliper
• Identify the Collet using the chart below
and select the correct size for the flange.
The Secure Grip collets are
consumable items. The lifespan of a collet
will vary depending on the flange materials
with which it is used. To increase the lifespan
of the collets it is recommended that they
are flipped through 180° on the collet holder,
this will produce more even wear across the
four ridges on the outer profile of the collet.
See Section 5.4 for details on collet removal
and replacement.
