WHAT IS A SET TOOTH
NARROW BAND SAW BLADE?
WHAT MAKES THEM GOOD, BETTER OR BEST?
FIRST: The band is a
strip of steel, whose quality and dimensions are controlled by the
blade manufacturer. The more malleable and flexible the steel, the
higher the price. Quality, flexible steel dramatically increases band
blade body life.
SECOND: The tooth gullet and pitch are either milled, crush ground or
stamped out. Milling is the ultimate way to produce a finished tooth
configuration with a smooth, frictionless surface and superior
sharpness. Crush grinding is much quicker and cheaper than milling,
but produces only a 55% finish. Stamping, even after tip filing or
kiss grinding, produces at best, a 23% finish. A dedicated gullet
geometry, geometrically designed for the work it is intended to do,
not only increases cost in its manufacturing time but also
dramatically increases the tooling cost necessary to produce the tooth
configuration. The gullet and its geometry make or break the overall
life of the band.
THIRD: Tile setting of the teeth is done next. Although setting is
universal, how accurately and where you set the tooth again influences
band saw blade life.
FOURTH: Heat treating and straightening of the tooth and band body is
done. This process can run the gamut from state of the art full
service electro heat induction hardening all the way down to the
antiquated flame hardening process. As you can imagine full service,
state of the art induction hardening cost a lot more than the cheaper
methods of electro induction tip hardening or flame hardening.

FACTS
- The more flexible and
malleable the steel the more dramatically lower the
tension applied to the body of the band must be. This
intentional use of low tension, high quality steel gives
you increased band body life and proportionally increases
the overall life of your machine's bearings, shafts and
wheel surfaces. The horse power needed to run a special
low tension band averages 30% less
- A milled, dedicated tooth
geometry lasts at least 50% to 75% longer in total service
time, over any other method of manufacturing.
- State of the art heat
treating does dramatically increase overall band body
life.
- To my knowledge there is
only one manufacturer of Band Saw Blades made on Earth
that IS all of the ABOVE!!! GSCHWIND GROUP!

HOW TO CHOOSE CORRECT LENGTH OF
BLADE
- Put the pulleys or wheels in
working position.
- Determine distance from center of
hub on upper and lower wheels (letter C on chart).
- Determine radius of upper and
lower wheels (R1 & R2 on chart).
- Apply formula as follows, for
correct length of band saw blade:
(R1 x 3.1416) + (R2 x 3.1416) + (2 x C) = Length
