Portable pipe cutting tool is used in areas of limited space. The pipe is clamped in the tool and then cut by a rotating cutter assembly that is internally connected to a drive shaft engaged in the chuck of a portable electric drill. The tool is held in a fixed position during the cutting operation

Pipe Cutting Tool is Useful in Limited Space 
CI-f+ 
Rotatable 
Arm 
The problem: 
To design a pipe cutting tool suitable for use in 
areas of limited space. 
The solution: 
A portable tool in which the pipe is clamped and 
then cut by a rotating cutter assembly that is internal-
ly connected to a drive shaft engaged in the chuck of a 
portable electric drill. The tool is held in a fixed posi-
tion during the cutting operation.
How it's done: 
The rotatable arm is opened to allow insertion of 
the pipe, which is then clamped in place by closing the 
rotatable arm, tightening the cutter assembly lock 
knob, and inserting the locking pin. The blade cutting 
pressure is then adjusted and a portable electric drill 
is connected to the cutter drive shaft. 
As the cutting progresses, it may be necessary to 
tighten the cutting pressure adjustment knob from 
(continued overteal)

time to time until the pipe is severed. When cutting is 
completed, the clamping members are opened and the 
blades are backed off to prevent accidental overload-
ing of the cutter assembly at the start of the next 
cutting operation.
