Introduction
Thank you for purchasing a Kurt vise. You have just purchased one
of the best machine vises in the industry. The D-Series AngLock vise
has a time proven design. The outstanding accuracy of this product
is second to none. Backed by a lifetime warranty, this product will last
forever when used and maintained properly.
The original Kurt Anglock vises are designed for precision clamping on
basic machine tools such as knee-type mills, grinders and machining
centers. They can be used for but are not limited to operations like
precision boring, drilling, tapping, grinding & nishing.
The patented Anglock design allows the movable jaw to advance in
such a way that each pound of force forward induces a ½ pound force
downward which minimizes the jaw lift and increases accuracy. This
combined with the needle bearings increases jaw clamping pressure.
Other features include: 80,000 psi ductile iron body, hardened vise bed
& jaw plates, semi-hard steel screw.
Introduction

(hardened) produces

Set-up Instructions
Now that you have your new Kurt Vise, it’s time to set-up and begin
using it. You will see that your new vise comes with a Kurt swivel
handle, chip guard and instruction manual in the shipping carton. The
chip guard rests between the ways of the vise and can be trimmed to
size to help keep the chips out of the screw. The handle is specically
designed to provide maximum torque to your vise. Your vise should
be mounted to a clean, at surface. The surface and the vise must be
free of any chips, dirt or debris of any kind. The mounting surface can
be honed if necessary. Clean the bottom of the vise with solvent or
other cleaner if needed.
To minimize vise bed deection, clamp your Kurt vise to your machine
table, pallet, or sub-plate using the built-in clamping slots provided.
Additional clamping can be used, but may not be necessary. Please
be sure to exercise good judgment when securing your vise to the
mounting surface. Be sure your vise is secured and will not move when
applying the machine pressure.

Operating Instructions
For proper vise operation insert the handle on to the hex end of the
vise. Rotate clockwise to clamp and counterclockwise to unclamp your
vise. This handle, combined with the correct amount of torque will
provide you with all the clamping force you will need to machine your
parts. DO NOT use any other type of pressure to open or close your
vise.
The uses of handle extensions, air impact wrenches, breaker
bars or hammer strikes are not recommended and will void the
warranty if used. This will also cause damage to the thrust bearing
and screw threads. If you need more clamping force you may require a
larger vise.
To properly clamp a part in your Kurt vise you should place the part in
the center of the jaws resting on the ways of the vise. Clamping only
on one side or above the movable and stationary jaws can result in jaw
lift or loss of accuracy. (See Fig. 1 on next page)
If one-sided clamping is necessary you MUST use a dummy part on
the other side. When using parallels or step jaws you must select a size
that keeps the bottom of the clamped part at or below the top of the
movable and stationary jaws. Always use jaw plates for clamping. If jaw
plates are not used damage to the mounting surface of the movable
and stationary jaw will occur. This will result in reduced clamping
accuracy and repeatability.

Operating Instructions

Operating Instructions
Proper O-Ring installation and usage
Proper Chip Guard installation and usage
Most jobs require a tight contact between the workpiece and the
parallels (see above). This option oered by Kurt Manufacturing
Company is ideal for that. The O-Ring installation will provide for the
movement needed when working with parallels.
Note: We do not recommend using this option with step jaws.
Installation: Install the O-Ring in the movable jaw as shown above in
two places. Tighten the adjustment set screw for a .002” space under
the front face of the movable jaw, then the jaw will tighten down
during clamping and provide down movement, pulling the part onto
the supporting parallel.
Example: Part plus 1 1/2 inches = Length of Chip Guard stock.
Note: Remove Chip Guard stock to lift vise. Corners of Chip Guard
stock if left extended as shown above could cause injury.
CAUTION:
Chip Guard stock shown above is provided to keep chips
from the nut and screw assembly and must be cut and
deburred to meet your application and safety needs.
*This Chip Guard stock should be cuto to ll the opening
between jaw plates.

10 ENGLISH | Maintenance Schedule
Maintenance Schedule
It is very important to perform regularly maintenance on your Kurt vise
to assure proper operation. Improper maintenance will result in poor
vise performance and may void your warranty.
Daily/ Weekly
1. Remove chips from surface of vise.
2. Visually inspect for chips, seals for damage and cleanliness.
3. Visually inspect for chip entrapments and remove when necessary.
4. Air-dry and apply rust inhibiting oil to the machined surface of the
vise.
Monthly
1. Open the vise to the maximum opening.
2. In the back of the movable jaw (handle end, center hole) loosen
the socket head set screw (approx. 6 turns) With the hex key (Allen
wrench) in the set-screw socket lift up and forward to pivot the Jaw
o of the vise bed.
3. Slide the Jaw slightly toward the stationary jaw and lift up to
remove the jaw from the“hook” of the nut. Note: A spherical
segment (shaped as ½ of a steel ball) is inside the cavity of the
movable jaw and may fall out as the jaw is removed. Take care not
to lose or misplace the spherical segment.
4. Turn the movable jaw over and clean the inside cavity. Also clean
the spherical segment.
5. Remove chips, clean and apply a light coat of machine oil to the
machined surface of the following item:
a. Nut & Screw assembly (clean exposed threads on the screw)
b. Bed of vise (top of“rails”)
c. Inside of the vise between the center ways.
6. To re-assemble the movable jaw, apply a“glob”of grease to the
under side of the movable jaw in the pocket. Place the spherical
segment in the mating pocket and push into the grease. The
grease will hold the segment in place when the jaw is turned over
to replace.
7. Tip the jaw so the front of the jaw (the side with the jaw plate) is
on the vise bed. Lower the jaw on to the bed so that the segment
contact the hook part of the nut and rest the jaw on to the vise
bed.

setscrew ¼ turn (approx.) note: DO NOT leave the setscrew
tightened rmly to the nut as this may cause improper operation.
The movable jaw is designed to move slightly (pivot side to side)
so maximum jaw plate contact is maintained when clamping out-
of-parallel, sawed, or cast parts.
9. Your vise is now ready for use. Open and close your vise to check
for proper operation. Center the part to be clamped in the vise and
close. Your parts should be centered from side to side to insure
proper clamping. (See Fig. 2 below)
