The powder metal steel alloy in
the blades reduces heat buildup,
a big factor in blade deterioration,
and the 2-by- 2 tooth geometry
removes debris for fast and clean
cuts. The first set of teeth cut
more aggressively, and then the
smaller reinforced teeth follow.
The right blade makes a
difference for jigsaws.
This alternating tooth pitch boosts
cutting speeds by 20 percent.
Jigsaws are also excellent
tools for making small or intricate cuts in metal, thanks to the
saws’ inherent maneuverability
and the small size of the blade.
It helps to choose the right
blade to match the application.
Available are blades specially
designed for aluminum, others
are intended for general metal
cutting, and some metal-cutting
blades are engineered with extra
flexibility to reduce the likelihood
the blade will break.
For cutting stainless steel,
Bosch offers the T118GFS bi-metal
blades for twice the life in such
difficult specialty applications. The
new bi-metal blades feature an 8-
percent cobalt steel additive to
increase heat and wear resistance.
This gives users a blade that
lasts twice as long as most other
bi-metal blades and costs much
less than blades with a carbide tip.
No matter what the tool you’re
using or what job you’re performing, remember that safety should
reign supreme when cutting
metal. The process is tough on
blades, typically generates lots
of heat, and there is the risk of
breakage from the blades or the
stock material, which can lead
to flying debris. Never force the
tool, and always wear hand and
eye protection. When cutting at
long intervals, it’s also wise
to wear hearing protection, and
always avoid working around
flammable materials when producing sparks. EHT
