Introduction
The 4" Model T10065 and 6" Model T10066
High-Precision Double-Clamp Milling Vise feature
mobile jaws on each end and a removable fixed
jaw in the center. This provides a wide variety of
secure clamping options when working with complex workpieces, all while delivering over three
tons of clamping pressure.
The vise can securely clamp onto a single workpiece using one set of mobile jaws, or clamp
multiple workpieces of the same or different sizes.
The vise can also be converted to a traditional
vise by removing the fixed center jaw and fixing
the step-side jaw to the body using the provided
step-side lock plate.
Additionally, the vise can be fitted with different
jaws and jaw plates, providing the most precise
and secure holds possible for the workpiece.
(Additional plates and jaws sold separately.)

Clamp Milling Vise.

Vise is very heavy! Get another person to
help you or use hoist when lifting or placing vise. Wear heavy-duty leather boots for
foot and toe protection, and keep hands and
fingers away from all pinch points. Ignoring
this warning can lead to severe pinching or
crushing injuries!

Handle
To close vise:
1.
Rotate handle clockwise to bring vise jaws
back toward center. Fore-side jaws will move
first, stopping after lightly clamping fore-side
workpiece. Step-Side jaws will then begin to
close.
Once both sides contact their workpieces,

apply final tightening pressure. Force will
automatically be evenly distributed to both
sides (see Figure 4).
Figure 2. Identifying vise sides.
2. Once fore-side has opened completely, step-
side will resume opening. Continue opening
until there is adequate room to insert workpiece (see Figure 3). T10065 has maximum
clamping range of 3 1⁄2" using fixed center jaw,
while T10066 can clamp up to 4 7⁄8".
Note: There will be increased resistance
when turning handle once fore-side has been
opened completely and step-side begins to
open. This is normal.

Removing Fixed Jaw & Securing
Step-Side
By reconfiguring the jaws and jaw plates, this
vise can be adapted to handle almost any type of
workpiece. The fixed center jaw can be removed
and the step-side made stationary to clamp larger
workpieces.
The fore and step-side jaws can also be removed
along with the center, and replaced with machinable soft jaws. Soft jaws offer the precision of
hardened parallel blocks, and can be easily
machined back to perfection after frequent use.
In addition to the soft jaws offered by Grizzly,
many vise owners prefer to custom make their
own soft jaw sets out of aluminum, customizing
grooves and steps (often referred to as "jack
blocks") directly onto the soft jaws.
and remove set screw used to adjust jaw
against leadscrew nut (see Figure 7). Lift jaw
directly up to remove.

Jaw plates are also interchangeable and can be
used in a variety of ways. Additionally, jaw plates
can be bolted onto the opposite ends of the step

Note: Jaw plates can also be attached to
opposite ends of jaws. This allows for wider
