EP 424
I.D. MOUNT END PREP
The Speed Prep system is engaged by simply
pulling the feed handle outward. This advanced
feed mechanism creates the exact profile
hands free with a ready to weld lathe quality
finish and no heat affected zone. For simple
form tool usage or as a dedicated flange facer,
the Wachs EP 424 is also offered without the
Speed Prep auto feed system. More versatile
and powerful than any other machine of its
kind, the Wachs EP 424 sets the standard
in user friendly large diameter end prep
machines.

DESCRIPTION

The Wachs EP 424 with the patent pending
new Speed Prep auto feed system is a
precision I.D. mount end prep machine
tool designed to bevel, compound bevel,
J prep, face and counterbore pipe, fittings
and valves. Utilizing our revolutionary
mechanism that feeds simultaneously
in the axial and radial planes, it’s able to
machine any bevel or compound bevel
without templates, incline tool slides or
work stoppage. The EP 424 is powerful
enough to form tool from 4” to 16”
(DN100-400) through Schedule 160, and
single point from 4” to 24” (DN100-600)
up to a 6.5” (165mm) wall thickness.

in the bevel angle and the land that works
best for your application, all without work
stoppages or additional components.
