Tool holders can be quickly loaded and unloaded
using the lock lever. Tools up to
secured by tightening the tool holder set screws.
The thumb wheel rotates to adjust cutting tool
height. The tool post is rotated by loosening the
top nut.

To install a tool in the tool post:
1. Position tool in holder so cutting edge extends
just enough to allow tool to cut freely—but no
more. Cutting edge must be well supported
to ensure good cutting results and avoid
chipping.
Over-extending a cutting tool from the post
will increase risk of tool chatter, breakage,
or tool loosening during operation, which
could cause metal pieces to be thrown at
the operator or bystanders with great force.
DO NOT extend a cutting tool more than 2.5
times the width of its cross-section (e.g.,
2.5 x 0.5" = 1.25").

2. Secure tool with at least two set screws.
3. Adjust cutting tool height to spindle center-
line, as instructed in next subsection.
Aligning Cutting Tool with Spindle
Centerline
For most operations, the cutting tool tip should be
aligned vertically with the spindle centerline, as
illustrated in Figure 60.

centerline (viewed from tailstock).
There are a number of ways to check and align
the cutting tool to the spindle centerline. If nec-
essary, you can raise the cutting tool by placing
steel shims underneath it. The shims should be
as long and as wide as the cutting tool to properly
support it.
Below are two common methods:
• Move the tailstock center over the cross slide
and use a fine ruler to measure the distance
from the surface of the cross slide to the tip
of the center. Adjust the cutting tool height so
it is the same distance above the cross slide
as the tailstock center.
• Align the tip of the cutting tool with a tailstock
center, as described in the following pro-
cedure. For this to work, the tailstock must
be aligned to the spindle centerline (refer to
Aligning Tailstock To Spindle Centerline
on Page 38 for detailed instructions).
