NOTICE
• Drawings and/or pictures in this manual
may be exaggerated for clarity.
• The tool, along with this operating
and maintenance instructions manual,
­contains trademarks, copyrights, and/or
patented features that are the exclusive
property of Victaulic.
Victaulic VG824 Cut-Grooving Tools are
designed for cut grooving 8 – 24-inch IPS
carbon steel and AWWA size cast or ductile iron
pipe. Wall thickness capacity for the VG824 is
0.238 – 0.750 inch (thicknesses include any
linings).
Victaulic VG828 Cut-Grooving Tools for
specifications
Advanced Groove System
are designed for cut grooving 14 – 24-inch
carbon steel pipe only. The minimum pipe
wall thickness requirement for the VG828 is
“XS” (Extra Strong, 0.500 inch/12.7 mm). The
maximum pipe wall thickness capacity of the

• VG824 and VG828 tools are designed
ONLY for cut ­grooving pipe sizes,
materials, and wall thicknesses listed in
this manual.
Failure to follow this instruction could
overload the tool, resulting in reduced tool
life and/or damage to the tool.
TOOL BIT INFORMATION FOR
VG824 TOOLS
Standard, high-speed tool bits for VG824 tools
are designed with two cutting edges (with the
exception of tool bits for 22 – 24-inch sizes)
to provide long tool bit life. These tool bits are
re-sharpenable.
TM
During operation, the tool grips the pipe wall
between two external support rolls and an
internal drive roll. The tool travels around the
pipe circumference in a clockwise direction.
While being driven in a clockwise direction, the
tool pulls itself tightly against the pipe end. The
tool bit, which cuts the groove into the pipe,
is spring-loaded against the pipe and removes
material until the depth stop, mounted directly
adjacent to the tool bit, contact the pipe surface.
The pipe stop, mounted in the same arm as the
tool bit, prevents the tool bit from cutting further
into the pipe and ensures uniform groove depth.
VG824 tool bits for grooving iron pipe (gray or
ductile) are a single-edge, carbide-tipped design
This design is not suitable for re-sharpening.
Refer to the “VG824 Tool Bit/Pipe Stop
Specifications” table for further information.

VG828 TOOLS
WARNING
• DO NOT attempt to re-sharpen VG828
tool bits for cut grooving to Advanced
Groove System (AGS) specifications.
• Use of re-sharpened tool bits for cut
grooving to AGS specifications may
produce improper groove profiles.
Failure to follow these instructions may
cause improper product installation and
product failure, resulting serious personal
injury and/or property damage.

Operating and Maintenance Instructions Manual
POWER REQUIREMENTS FOR
THE VICTAULIC POWER MULE II
OR POWER DRIVE
DANGER
• To reduce the risk of
electric shock, check the
electrical source for proper
grounding.
• Before performing any
maintenance on the Power
Mule II or power drive,
disconnect the power cord
from the electrical source.
Failure to follow these instructions could
result in death or serious personal injury.
The VG824 and VG828 tools are designed for
use with the Victaulic Power Mule II and power
drives in conjunction with a secure pipe support
system. Power, speed, and safety requirements
must be verified before attempting to use any
power source other than the Victaulic Power
Mule II. All power sources must be equipped
with a safety foot switch for safe and proper
operation. If the power source is shipped without
a safety foot switch, contact the manufacturer.
The Victaulic Power Mule II is designed to
operate on a 115-volt, 20-Amp, 25 – 60 Hz,
single-phase power supply. In addition, a
220-volt, 8-Amp model is available.
Most other power drives are designed to operate
on a 115-volt, 15-Amp, 50/60-Hz power supply
or 220-volt, 8-Amp, 50/60-Hz power supply.
Victaulic recommends a speed control reducer
that is designed to operate on a 115-volt,
15-Amp, 50/60-Hz power supply. NOTE: Speed
control reducers work only with AC universal
motors that have brushes. DO NOT use speed
control reducers with induction-type AC motors.
The speed control reducer and the safety foot
switch for the Power Mule II or power drive
MUST be plugged into an internally-grounded
electrical outlet, in accordance with Article 250
of the National Electrical Code.
Extension Cord Requirements
When pre-wired outlets are not available and
an extension cord must be used, it is important
to use the proper cord size (i.e. Conductor Size
American Wire Gauge). Cord size selection is
based upon tool rating (amps) and cord length
(feet). Use of a cord size (gauge) thinner than
required will cause significant voltage drop while
the tool is operating. Voltage drops may cause
damage to the power source and can result in
improper tool operation. NOTE: It is acceptable
to use a cord size (gauge) that is heavier than
required.
The required cord sizes (gauges) for cord
lengths up to and including 100 feet/31 m are
listed in the table below. Use of extension cords
longer than 100 feet/31 m must be avoided.
Always refer to the operating and maintenance
instructions for the Victaulic Power Mule II or the
applicable power drive for detailed information.
Power Source Rating
Always refer to the operating and maintenance
instructions for the Victaulic Power Mule II or the
applicable power drive for detailed information.

6.As the tool rotates, generously oil the
area where the groove will be cut, as
shown above. Use a good-grade cutting
oil (i.e. Ridgid* dark thread cutting oil
or equivalent) on steel pipe only. For
aluminum or stainless steel pipe, use
a thread cutting oil that is formulated
specifically for these materials. DO NOT
apply oil on cast iron (gray or ductile)
pipe.
7a.The tool bit is advanced properly when
the leaf spring is approximately 3/8 inch
open from the stop nut on the leaf spring
adjustment post. Using the hand knob,
continue advancing the tool bit in 1/4-turn
increments every three or four rotations of
the pipe to maintain the proper spacing, as
shown above.
CAUTION
• An opening MUST be maintained
between the stop nut on the leaf spring
adjustment post and the leaf spring.
If the hand knob is turned enough to
eliminate this opening, the tool bit will cut
a chip that is too large, which may jam the
tool, overload the power drive, and/or shear
the serrated drive roll key.
7.Turn the tool bit feed knob gradually in
the CLOCKWISE direction to advance the
tool bit against the pipe while the tool is

pipe stop removal and
installation
VG824 and VG828 tools are designed to
“hug” the pipe end when driven in a clockwise
direction. The tool tries to pull itself as far as
possible onto the pipe end. The pipe stops
limit the distance the tool can pull itself onto
the pipe end, therefore controlling the “A”
dimension (distance from the groove to the pipe
end). The pulling action of the tool forces the
pipe stops against the pipe end, resulting in a
rubbing action between the pipe end and pipe
stops. Eventually, this rubbing action wears
down the hardened steel pipe stops, resulting in
longer “A” dimensions. When the wear results
in “A” dimensions that are not within Victaulic
specifications, the pipe stops must be replaced.
The two top and two bottom pipe stops are not
adjustable, but each of these pipe stops cover
many sizes.
The top pipe stops contact 8 – 12-inch IPS and
8-inch CI pipe sizes and must be removed for
larger CI sizes.
IPS pipe in 14-inch and larger sizes clears
the top pipe stops, which do not need to be
removed.
The bottom pipe stops contact 14 – 24-inch IPS
pipe and 10-inch and larger CI pipe.
When grooving certain sizes of CI pipe, the top
and/or bottom pipe stops must be changed or
removed. Refer to the applicable “Tool Bit/Pipe

The Victaulic Power Mule II is a high-torque
power drive for driving Victaulic Cut Grooving
Tools. The power mule operates at 13 amps with
a no-load operating speed of 32 rpm. Under
load, the power mule runs at slower speeds.
This is a very desirable feature, since heavier
loads and slower speeds greatly reduce tool-bit
chatter.

EXPLANATION OF CRITICAL CUT GROOVE DIMENSIONS
WARNING
• Pipe dimensions and groove dimensions must be within the tolerances specified in the
tables on the following pages to ensure proper joint performance.
Failure to follow these specifications could result in serious personal injury, property damage,
joint leakage, and/or joint failure.

Pipe Outside Diameter – Nominal NPS Pipe Size (ANSI B36.10) and Basic Metric Pipe Size
(ISO 4200) – The average pipe outside diameter must not vary from the specifications listed in the
tables on the following pages. Maximum allowable pipe ovality should not vary by more than 1%.
Greater variations between the major and minor diameters will result in difficult coupling assembly.
For IPS pipe, the maximum allowable tolerance from square-cut pipe ends is 0.060-inch/1.5-mm
for 8-inch/200-mm and larger sizes. This is measured from the true square line. Any internal and
external weld beads or seams must be ground flush to the pipe surface. The inside diameter of
the pipe end must be cleaned to remove coarse scale, dirt, and other foreign material that might
interfere with or damage the drive roll.
For pipe being grooved to Advanced Groove System (AGS) specifications, the outside diameter
must not vary from the specifications listed in this manual (API 5L end tolerance). The maximum
allowable tolerance from square-cut ends is 0.063 inch/1.5 mm. This is measured from the true
square line.
“A” Dimension – The “A” dimension, or the distance from the pipe end to the groove, identifies the
gasket seating area. This area must be free from indentations, projections (including weld seams),
deep pits, swells, and roll marks from the pipe end to the groove to ensure a leak-tight seal. All
foreign material, such as loose paint, scale, oil, grease, chips, rust, and dirt must be removed. For
cast pipe, peened surfaces may require corrective action to ensure a leak-tight seal.
“B” Dimension – The “B” dimension, or groove width, controls expansion, contraction, and angular
deflection of flexible couplings by the distance it is located from the pipe and its width in relation to
the coupling housings’ “key” width. The bottom of the groove must be free of all foreign material,
such as dirt, chips, rust, and scale that may interfere with proper coupling assembly.
For pipe being grooved to AGS specifications, the corners at the bottom of the groove must be
radiused. The Groove Width “B” dimension will be achieved with properly maintained Victaulic
VG828 tools that are equipped with a Victaulic-supplied AGS tool bit.

Operating and Maintenance Instructions Manual
“C” Dimension – The “C” dimension is the proper diameter at the base of the groove. This
dimension must be within the diameter’s tolerance and concentric with the OD for proper coupling
fit. The groove must be of uniform depth for the entire pipe circumference. For pipe being grooved
to AGS specifications, the VG828 tool must be equipped with a Victaulic-supplied AGS tool bit.
“D” Dimension – The “D” dimension is the normal depth of the groove and is a reference for a
“trial groove” only. Variations in pipe OD affect this dimension and must be altered, if necessary, to
keep the “C” dimension within tolerance. This groove must conform to the “C” dimension described
above.
“T” Dimension – The “T” dimension is the lightest grade (minimum, nominal wall thickness) of pipe
that is suitable for cut grooving. Pipe that is less than the minimum, nominal wall thickness for cut
grooving may be roll grooved.
For AWWA pipe, the tolerances must conform to Class 53 ANSI/AWWA C151/A21.51.
For pipe being grooved to AGS specifications, the absolute minimum wall thickness is
0.500 inch/12.7 mm. The maximum allowable wall thickness is 0.750 inch/19.1 mm.
“R” Dimension – The “R” dimension is the radius necessary at the bottom of the groove to
eliminate a point of stress concentration for cast pipe (gray and ductile) and PVC plastic pipe.
rigid and flexible radius cut grooves
Rigid Radius Cut Groove
Exaggerated for Clarity
Flexible Radius Cut Groove
Victaulic groove specifications for cast pipe (gray and ductile) conform to the requirements of ANSI/
AWWA Standard C-606 and CSA B242.
For cast pipe, the groove is cut with a radius (“R” dimension) at the corners of the groove base to
reduce stress concentration. Grooving dimensions are the same for any pipe OD, regardless of pipe
class and pressure.
Standard preparation is with a rigid radius cut groove. Flexible radius cut groove dimensions may be
used to provide expansion/contraction or angular movement allowance at the joint.

‡ A 0.562-inch width groove is required for 22 – 24-inch pipe sizes in order to obtain the maximum allowable pipe end
movement. The 0.500-inch groove width will provide half the maximum allowance for 22 – 24-inch pipe sizes. For the 8-inch
pipe size, the 0.500 groove width does not change the allowable pipe-end movement.
