DESCRIPTION

Wachs SDB 412/2 is a hand held beveling machine
that delivers maximum power and performance
for fast, accurate O.D. weld preps on pipe and
tube from 4” thru 12” (101 - 305mm) up to
1.125” (29mm) wall. The SDB 412 is designed to
face, bevel and counterbore simultaneously
on carbon, stainless and high alloy steels. A
proven workhorse, it sets up quickly with a self
centering mandrel and chuck assembly that
mounts to the pipe I.D. The SDB 412’s design
means one person can set up, operate and
create perfect weld preps in minutes.
VERSATILE DESIGN

Like the smaller SDB 103 and 206, the SDB 412
is highly versatile. It’s ideal for machining
thin wall pipe, heavy wall tube, prepping tees,
elbows and valves and (with the optional FF
kit) flange facing. Its compact design requires
minimal operating clearance. The strong yet
lightweight aluminum and hardened steel
construction allows for ease of handling with
fast setup and operation.
The optional FF Kit converts the SDB 412 to the
FF 424 Flange Facer for facing raised and flat
face flanges from 4” I.D. to 24” O.D. (102mm I.D.
to 610mm O.D.) With the FF Kit your SDB 412 can
be used for both end preps and flange facing,
making it highly cost effective. Easy to set up,
easy to operate and easy to get a perfect weld
prep, Wachs SDB 412 is an easy choice in large
diameter end prep machine tools.
