Ratchet pipe cutter for
automotive applications
The Dako No 224 ratchet pipe cutter is ideal
for retrofitting catalytic converters and soot
particle filters as well as for replacing parts
of vehicle exhaust systems. Depending on
the surrounding area, the exhaust simply
needs to be pulled down far enough to
allow room for the cutter head to rotate
around the pipe.
No sawing or grinding is required, thereby
eliminating the risk of injury to the user and
avoiding any possibility of the underside of the
vehicle being damaged by sawing or grinding.
The cutting produces no swarf, so that no
chips or swarf can enter the exhaust system.
The cut is clean and needs no tidying up,
so the new sections of the exhaust can be
fitted immediately after the pipe has been
parted off. This results in considerable time
saving over conventional methods.
The ratchet drive features automatic
advance of the cutting wheel with every
turn. The special alloy of the cutting wheel
gives a long tool-edge life and ensures
fast work, while the body of the pipe cutter
is made from rugged, easy-care die-cast
aluminium.
The Dako No 224 ratchet pipe cutter is
designed for parting plain steel, stainless
steel, copper and aluminium tubes. It is
available in two sizes – 16mm to 35mm
pipe diameter and 35mm to 66mm pipe
diameter – with wall thicknesses from
1.5mm.

The company also produces automatic
cutting systems and customized machines

In the area of nesting cutting, ISTech
offers a wide variety of solutions with
different types of nesting fixtures. The best
solution can be selected according to the
shape and dimension of the material and
the bundle. It is even possible to operate
some of ISTech’s nesting fixtures without
adjustment. Other nesting fixtures require
some manual adjustments, but the bundle
vice guarantees a minimum butt end.
ISTech nesting fixtures are made up of one
fixed vice mounted onto the machine frame,
and one movable vice mounted onto the
material feeder. These two vices, working
together, guarantee a perfect clamping of
the bundle and eliminates any possible
vibration that can reduce the life of the
blade.
In addition, special plastic components are
mounted on the vice clamping face to secure
the bundle and absorb any residual vibration.
All ISTech nesting fixtures are hydraulic and
use the machine’s maximum cutting capacity.

and state-of-the-art technical solutions.
As standard, the numerically controlled
