Cutting a Recess in Concrete Pipe (Fig. P)

WARNING: Before making any cuts, make sure the
pipe is properly secured on a non-slip surface.
Several cuts are needed to make a recess cut in
concrete pipe and it is important to make the cuts in the
proper sequence.
1. First make two cuts along the length of the pipe.
Always make an axial cut to avoid pinching of the
cutting wheel.
2. Insert wedges into the cuts.
3. Make the third and fourth cuts to complete the recess.
4. If the severed part remains after all four cuts are made,
do not make any more cuts. Break the severed part out.
