BLADE BREAK-IN LONGER BLADE LIFE BAND SAW SERVICE

BLADE BREAK-IN LONGER BLADE LIFE BAND SAW SERVICE
BLADE BREAK-IN
Using the right break-in procedures for a bimetal blade assures longer blade life, faster
cuts for a longer period of time and consistent
performance. Conversely, blade life can be
significantly compromised if the proper break-in
procedures are not followed.
LONGER BLADE LIFE
NEW BLADE WITH
RAZOR SHARP TEETH
TOOTH CORRECTLY
BROKEN IN
The teeth on a new band saw blade are razor
sharp. To withstand the cutting pressures of band
sawing, the tip of each tooth should be honed to
create an extremely small radius on its tip.
Easy-to-cut material such as carbon steel and
aluminum:
A.Run the normal surface feet per minute (SFPM).
B.Adjust the feed pressure to about one-half the
normal cutting rate for the first few cuts or for
50-100 square inches (323-645 sq.cm).
C.Increase to the normal cutting rate.
D.Avoid vibration.
Hard-to-cut materials such as nickel-based
alloys like inconel, hardened steels,tool steels
and stainless steels:
A.Run the normal surface feet per minute (SFPM).
B.Adjust the feed pressure to about threequarters of the normal cutting rate for the first
few cuts or for 25-75 square inches (161-484
sq.cm).
C.Then increase the cutting rate part way to
normal for the next few cuts.
D.Then increase to the normal cutting rate.
E.Avoid vibration.

Starrett service technicians can also instruct saw
operators on achieving the best performance of
blade and machine for your applications.
Contact your Starrett Band Saw distributor about
arranging a visit to your workplace by a Starrett
service technician.

BAND SAW BLADE INSTALLATION
GUIDELINES
Always follow the machine manufacturer’s instructions
and recommendations for blade changes and the
safe operation for the band saw machine. The
guidelines are not intended to replace the machine
manufacturer’s instructions or recommendations. The
general information contained in the guidelines is
intended to assist in the proper installation of band
saw blades. Proper blade installation achieves more
efficient blade performance. Please contact your
machine manufacturer for appropriate procedures

BASIC BLADE CHANGE GUIDELINES
cPosition
saw head to appropriate location to
facilitate ease of blade change.
cFollow
required lock out tag out procedures.
cPosition
chip brush away from saw blade.
