Orbitalum Tools offers a large choice of
durable stainless steel clamping shells for
different diameters. These ensure precise
mounting of micro fittings and quick change
of clamping shells without tools. Both
machines come with a robust, padded hard
case.
With the patented Quick-Tool-Change
clamping system, the user is able to change
tools quickly and easily; the integrated
multifunctional tool has two cutting edges
and a high-performance surface coating
which prevents wear and tear, allowing
pipes to be processed quickly and cost-
effectively, with high precision.

Osborn International manufactures brushes
and abrasives for use in the industrial, trade
and private sector.
Steel wire brushes are an ideal solution for
the cleaning of welded seams. They are
a cost effective and practical method for
removing welding cinder and beads that
prevent the next seam from being applied.
The use of cellulose and alkaline electrodes
is insignificant, as a brush will carefully
remove all types of cinder.
A rotating wire brush will provide a clean
welded seam without having to remove up
to 30 per cent of the welding material, as is
inevitable with a grinding disc.
Any defects in the weld seam also become
immediately visible, enabling any rework to
be carried out promptly.
The use of steel wire brushes reduces
the number of seams by a claimed 30-50
and micro fittings up to 63.5mm (2.5″) OD,
providing a solution for the demanding
preparation of pipe-ends for orbital
welding.
Facing of pipes and micro fittings from
unalloyed, low alloy and high alloy steels,
with an outer dimension range between
6.35 and 63.5mm (0.25″ to 2.5″) and a
maximum pipe thickness of 3mm (0.118″)
is no problem for the electric and cordless
drives.
The clamping shells of the RPG 1.5
machines can also be used with the RPG
2.5, due to the use of a special adapter
clamping shell included with the machine.
