COLLET CHUCK USE: The XPS-16 Collet Chuck
uses ER-25 collets to hold the drill. The chuck is
designed to use one or two collets to clamp the
drill. Depending on the drill type and length, ei-
ther the forward collet, the rear collet or both col-
lets can used to secure the drill. The collet sys-
tem offers the same performance and size range
as the standard chuck although use of the rear
collet by itself will degrade the run-out precision
somewhat. Collets are offered in both Metric and
English sizing.
To use the Collet Chuck, determine which collet
configuration will best suit your needs. The
sketch below shows the dimensions of the collets
in relation to the machine home position. It can
be used to visualize which collet configuration to
use.
To use the forward collet only, remove the
Primary Knob and insert the appropriate collet into
the Collet Sleeve as shown below.
Install the Primary Knob into the Collet Chuck
Spindle and tighten until contact of the collet is
felt. Then back-off the knob ¼ turn. Insert the
drill through the collet as normal and then tighten
the knob until snug.
You are ready to sharpen the drill.
