High performance tube
cutting TCT saw blades
TRU-CUT Saw Inc is now offering its Aggressor-XL line of thin kerf,
carbide tipped saw blades for cutting tube, pipe and solid ferrous
materials in flying cutoff and re-cutting applications. Available with
carbide and cermet inserts, these PVD coated blades offer huge
performance gains over high-speed steel and friction saws.
As the name suggests, Aggressor-XL blades cut fast – up to
1,500 SFM. Test data on a 350mm x 2.8mm x 100 tooth blade
running at 250 RPM achieved a 3.7 sec. cut time and was able to
cut six square metres of 52100 bearing steel.
A special chip breaker on the face of the inserts allows faster
chip removal and more aggressive cutting speeds.
Tru-Cut Saw is the only circular saw blade manufacturer in the
US with its own PVD coating chamber. This allows the company
to tightly control coating quality and uniformity, and allows
adjustments for individual customer applications.
ATru-Cut Saw Inc spokesman said: “We customise saw blades
and mounting patterns to individual customer requirements and
provide them with the exact blade for the job.”

Pipe expanders
FONTIJNE Grotnes is a specialist in the design and construction
of pipe-end and full length pipe expanders for the pipe industry.
The Fontijne Grotnes Expander ensures a constant, reproducible
process regarding diameter and mechanical properties. The
design maximises the radial forces in order to obtain maximum
output in relation to pipe dimensions.
A full length pipe expander is an essential part of the
production process in a pipe mill. The pipe expander process
makes the welding of the pipeline in the field easier, even for
cut pipe sections. Fontijne Grotnes is constantly improving and
preparing the full length pipe expander process for new market
demands, such as higher outputs, thicker wall thicknesses,
higher material grades up to X120, and stricter ovality and
straightness tolerances.
The company’s Straightening System is designed for small
pipes ranging from 16" to 30". The system controls the straightness
of the pipes in all directions within ½ -API- and DNV-standards.
The Fontijne Grotnes pipe-end expander sizes the end of large
diameter pipes to parallel-, spherical- and semi-spherical joints.
The joints are applicable for, among others, SSAW pipes, mainly
used for conveyance of water and sewage.
In February, Fontijne Grotnes opened a new office in Beijing,
China. This office represents the company in the Chinese market,
and is expected to strengthen its position in the pipe, wheel and
metal forming industry.
