INSTALLATION PROCEDURES
FOR CAST IRON
power are used primarily in fabrication work or high-volume
cutting operations. Examples of this type of equipment
include the abrasive saw (sometimes called a chop saw),
the power hack saw, and the electrically actuated hydraulic
snap cutter. The abrasive saw is an efficient tool for cutting
8” and larger pipe.
There are two types of hand-powered cutting tools used in
the industry today: the standard steel pipe cutter uses cutting
wheels designed specifically to cut cast iron soil pipe; the
snap cutter is used more commonly to cut cast iron soil
pipe in the field. Several types of snap cutters are available.
Cutting Cast Iron Soil Pipe with a Snap
Cutter
1. Read and follow instructions from manufacturer of the
snap cutter.
2. Measure the required pipe length and mark it for the

CUTTING METHODS FOR CAST IRON
SOIL PIPE
There are several methods of cutting cast iron soil pipe.
They may be grouped into two basic categories: those that

and/or bystanders:
• Always read and follow the machine/tool manufacturer’s
instructions.
• Always secure pipe before cutting so that it cannot roll,
drop or slip.
Failure to follow proper installation practices,
procedures, or techniques may result in personal injury,
system failure or property damage.
• Always use protective equipment including eye
protection and safety clothing while installing or cutting
pipe.
• Power equipment can be dangerous if used improperly.
Always review and carefully follow the manufacturer’s
operating and safety instructions.
3. Position the snap cutter’s chain squarely around the
pipe to assure that the cut is straight. Set the chain so
that the maximum number of cutting wheels come into
contact with the pipe.
4. Score the pipe by applying pressure on the handles,
which causes the cutting wheels to indent the pipe’s
