steel pipe cutting saw blade diameter from 280mm up to 1800mm
This type of TCT Circular Saw Blades are are specially designed as
steel pipes cutting blades. The blades are applied in seamless
steel pipe plant to cut various hot-rolled seamless pipes after
cooling and straightening. Several parallel pipes can be cut at one
time which increases the efficiency and quality. The blade also can
be used to cut cast iron and non-ferrous metals like aluminium,
cooper, brass etc…

There are four basic blade types, determined by the shape, or
grind, of their teeth. They are flat top grind (FTG), alternate top
bevel (ATB), combination (ATBR), and triple-chip grind (TCG)
[Figure 1 and Photo A].
FTG blades have teeth whose top edges are square to the saw plate.
Also called rakers, these teeth attack the wood much like a chisel
chopping out the ends of a mortise. They’re fast cutting and
durable, but don’t produce a clean surface. They’re designed to
rip, sawing perpendicular to the grain.
The teeth on ATB blades are angled across the top edge, with every
other tooth “leaning” in the opposite direction. The shape of the
tooth causes it to shear the wood fibers cleanly using a slicing
motion. The steeper the bevel angle, the cleaner the teeth cut, but
the quicker they dull (Figure 2). Most 40-tooth ATB blades are
marketed as “all-purpose” blades.
Combination blades consist of 50 teeth arranged in sets of five,
with four ATB teeth followed by a raker tooth (thus the ATBR
designation.) The ATB teeth are designed to crosscut cleanly while
the raker teeth aid in ripping. Combination blades are also
considered “all-purpose” blades.
The teeth on a TCG blade alternate between a raker tooth and a
chamfered tooth. The chamfered tooth roughs out the cut, while the
following FTG tooth cleans it up. This tooth configuration is meant
for sawing dense materials: plastic laminate, solid surface
materials like Corian, and non-ferrous metals like brass and
aluminum. Pointy ATB teeth would blunt quickly from this stuff.
