Danfoss hydraulic hose cutting system is break-through technology using a toothed blade, cutting with the backs of each tooth, so the
blade does not take a kerf. The saw bends the hose into the blade spreading the cut edges to avoid burning and smoking.
Old Method
The normal sawing method of lowering an abrasive saw blade onto the hose causes the
hose to compress and deform. As the blade cuts the compressed hose expands against
the blade causing friction, heating and burning and much of the debris from the kerf of
the blade is deposited into your hose.

New Improved Danfoss Method
With the Danfoss hydraulic hose saws the hose is positioned
across two pins (A) and moved into the blade (C) by a feed
foot (B) using a pulldown handle for better leverage on
heavy hose. The feed motion causes the hose to stretch at
the point of contact with the blade, allowing it to separate
as it is cut (see image below). This separation allows the
hose to pass clear of the saw blade with LESS friction, LESS
heating and LESS DEBRIS! A vacuum hose (not shown) is
attached to a vacuum port (D) to remove any tiny amount of
debris or smoke during cutting. Improved safety using 110V
on/off switch with a magnetic contactor. When power is lost,
the saw will not turn back on independently.
