Best bite by far
We think you’ll want to make friends with the
New Sandflex hacksaw blade. Not only does it
cut faster than competing blades. It lasts
longer, too.
Proof?
We put our new blade to the test. Laboratory
results showed that it cuts 20% faster than its nearest
competitor.
We didn’t stop there.
In a controlled field test, 50 professional users were asked to
compare the New Sandflex blade with three leading brands.
The majority said they preferred the New Sandflex. They
particularly liked its authoritative bite and smooth cutting
performance: the ”comfort factor.”
How do you make
the world’s best blade?
We introduced Sandflex over 30 years ago as the world’s first
bi-metal hacksaw blade. Since then, we’ve continuously
developed the blade to cut faster and faster.

From the outset, we knew this: If you want to
make the fastest blade in the world, you have
to rely on a whole set of interlinked techno-
logies. And not just one single improvement.
So we launched an investigation.
Our technicians examined the teeth of
typical hacksaw blades, which are usually
milled. And found that milled teeth simply
aren’t sharp enough.
Instead, the teeth should be precision-ground to the finest
tolerances.
We went on to examine tooth geometry.
Tests proved that teeth with a positive rake angle are more
aggressive. They bite better. So we decided to use a
steel alloy that makes tooth edges more resistant.
They’ll last longer.
The crowning result is the New Sandflex hacksaw
blade. A bi-metal blade that cuts faster and smoother.
Less strain for professional users.
But why take our word for it?
Give the New Sandflex a try. Discover why it’ll consolidate our
position as the No. 1 global brand.

The job gets done faster
We asked 50 professional users to compare the New Sandflex
blade with three other leading brands — two with ground
teeth and the third with milled teeth.
All the blades were repainted to look exactly the same. The
pros then tried them out, always using the same hacksaw to
cut through an ordinary steel pipe with a diameter of 20 mm.
The results were revealing.
The majority of the users preferred the New Sandflex to any
of the others. They explained that Sandflex had the best bite
and was ”easier to use.” Who wants an uncooperative blade that
makes the job tougher?

Cuts 20% faster
Our R&D Center in Sweden used standard laboratory methodo-
logies to determine why our new blade is the world’s sharpest.
The four brands that competed in the field test were now subjec-
ted to a specially built test cutting machine with a feed force of
20 kg (200 N).
Its stroke rate of 85 strokes per minute is equivalent to a manual
cutting rate. The workpiece consisted of a ground steel bar
SS2541 (AISI 4377) with a diameter of 20 mm.
The New Sandflex cut 50 sections from the steel bar nearly 20%
faster than its closest competitor. The New Sandflex blade also
had the highest ”MRR” value, that measures the removal of
material from the workpiece in mm3per second.

In another laboratory test at the Center, the New Sandflex blade
was shown to have 35% longer life compared its closest
com-petitor. In other words, it withstood 35% more strokes
before wearing down.
In this new century of time-based
competition, professional users want
speed and durability.
Why settle for less?
That’s why they’ll turn to the New
Sandflex bi-metal blade. It cuts faster, with less effort. And lasts
longer, too.
