Raker set
In the raker set, one tooth is set to the left, one tooth is set to
the right, and one tooth (raker) is unset. This set type is
used on most evenly pitched blades such as regular and
hook. It is also used for contour and friction cutting blades
on vertical bandsaw machines.
Band Width

Check frequently:
• The operation of the chip brush.
• The wear and alignment of the guides.
• The band tension with a tensionmeter (see page 29).
• The band speed with a tachometer (see page 29).
• The coolant concentration with a refractometer
(see page 29).
Coolant / Cutting fluid
The coolant lubricates, cools and carries the chips from the
cut. It is important to:
• Use good cutting fluid.
• Use recommended concentration of cutting fluid.
• Make sure that the cutting fluid reaches the cut with

The number of teeth per inch (TPI) defines the pitch of the
blade and can vary from less than 1 to 24.
Thin-walled workpieces like tubes, pipes, sheet etc.,
require fine teeth, otherwise there is a risk of tooth damage
or breakage.
Large cross sections should be cut with a coarse-pitched saw,

General Information
Tooth pitch for solid workpieces
The diagram below will help you select the right pitch for
cutting solids.
The ideal choice is at the widest point of each field.
Example 1: When cutting a Ø 6 inch (150 mm) bar, use 2
TPI, if an evenly pitched blade is your choice.
Use a 2/3 TPI or a 1/2 TPI if you choose a
variably pitched blade.
Example 2: If you are sawing in soft materials like plastics,
aluminium or wood, choose a pitch two steps
coarser than recommended.
When cutting 1/2-3/4 inch (13-20 mm) thick pieces of
aluminium, use a 6 TPI or a 5/8 TPI blade.

General Information
Cutting pipes and profiles
The diagram below will help you find the right tooth pitch for
cutting pipes and profiles.
The recommended tooth pitch for cutting profiles is found in
the field where the width meets the wall thickness of the profile.
Example 3: When cutting a 4" x .4" (100 x 10 mm) U-beam,
select a 5/8 TPI or a 4/6 TPI blade.
The recommended tooth pitch is found in the
field where the outer diameter meets the wall
thickness of the pipe to be cut.
Example 4: When cutting a 1.5" x .06" (40 x 1.6 mm) pipe,
select a 10/14 TPI blade.

Tooth Shape Guide
Tooth Shape guide
Metal Cutting
(Evenly pitched)
The tooth shapes have different rake angles, clearance angles and gullet depths. This makes each tooth shape suitable for a
specific application.
Regular is a standard tooth shape
with 0˚ rake angle. Regular is the
traditional tooth shape for general
cutting of small, solid workpieces.
Positive PS has a 10˚-15˚ rake angle,
a curved back and a gullet with large
chip capacity. It is excellent for cutting
large workpieces of all types of steel.
Triple Set Xtra, with high/low, 3 tooth
pattern designed to give maximum chip
clearance and even chip load. This
blade with 10° rake is ideal for cutting
large difficult, abrasive materials.
Metal Cutting
(Variably pitched)
These tooth shapes should be used when there is a risk of vibration when cutting tubes, profiles and bundles. Generally, multipurpose blades are variably pitched.
Combo tooth shape is similar to
Regular. It is suitable for multi-purpose
cutting of thin-walled tubes and profiles
in most materials.
With its advanced design and Positive PS
teeth, Combo PS has optimum gullet capacity and is the ideal tooth shape for production
cutting, especially of alloyed steels.
Carbide Triple Set Xtra, Combo
same as the standard triple set xtra, but
with advantage of combo pitches to give
smoother, cutting action, low vibrations.
Combo PR, with a 5-10° rake angle,
and is mainly used on medium sized
to large workpieces when vibration
may occur.
Combo LK is a low kerf, combo
design to provide low vibration, long
life and good surface finish in multipurpose cutting applications. Available
in 3856-SANDFLEX® Multi-cut range.
Combo LZ is a low kerf, zero rake
combo design available in 4/6 TPI. It
provides a zero rake option within the
3856-SANDFLEX® Multi-cut range.
Specifically designed for difficult to cut
shapes, sections, tubes and bundles.
Metal Cutting
(Ground profile info)
Advanced tooth design of ground bandsaw blades will give, in combination with precise setting, superior surface finish and
extended tool life.
Combo PHG is a patented ground tooth shape with
positive rake angle designed for good penetration of large
sections of tough-to-cut alloys and workhardening materials.
Combo PSG is a new ground tooth shape with positive
rake angle. It is the ideal tooth shape for production cutting
meduim to large sections of a wide range of materials and
especially on alloyed and stainless steels.
Non-ferrous Cutting (Evenly pitched)
The tooth shapes have different rake angles, clearance angles and gullet depths. This makes each tooth shape suitable for a
specific application.
Hook has sharp teeth with 10˚ rake angle and shallow
gullets. It is used for cutting non-ferrous metals, wood
and plastics.
Carbide Triple Set with high/low, 3 tooth pattern maximum
clearance, and even chip loads. This tooth shape is ideal for
use on non ferrous alloys found in the foundry industry.

Sawing Aids
3870 — BandCalc™
A Software program, based upon input from users with regards to
material, machine, workpiece, economy and customer preferences,
will recommend the best bandsaw blade for the application. It will
also give necessary information on blade speed, feed rate and will
calculate a cutting time and cost per cut for the application.
BandCalcTM is a computer software programme that quickly and
simply determines the best bandsaw blade for a specific
application. And, having selected the blade, BandCalcTM will then
provide the correct cutting data. It is an excellent tool for users who
wish to improve production efficiency.
▼
BandCalcTM, which is Windows based and available on
CD Rom, contains up-to-date information on the entire
Bahco bandsaw assortment, details of over two and
a half thousand bandsaw machines and a database
of some 2,700 different materials of international and
country standards.
By using these databases and information input by the user,
BandCalcTM will select the best blade and give alternatives for the
specific application. It will also supply a cost per cut calculation
and accurate cutting data.
BandCalcTM is available in ten languages: English, Swedish,
French, Spanish, German, Dutch, Italian, Finnish, Japanese and
Russian.
• Please refer to BandCalc™ for a full, up to date,
Machine List.

Sawing Aids
Even the best blades need to run properly
tensioned and at the right speed. That is why we
offer a number of very important accessories that
will help to get the best performance out of our
quality blades.
3870 Tensionmeter
Bahco’s tensionmeter is designed for easy, accurate measurement
of the correct blade tension of all bandsaws.

Proper tension is necessary to provide straight cuts and long blade
life, thereby reducing the cost per cut.

Troubleshooting Guide
Machine
Important Facts
Band Breakage
Crooked Sawing
Guides and guide arms
Check and adjust the guides regularly.
Check if worn out and replace if necessary.
Position guide arms as close to the workpiece as possible.
Guides worn out
Guide setting too wide
Guides too far apart
Guides worn out
Guide arm loose
Guides poorly adjusted
Band wheels
The wheels have to be kept in good condition and
should be properly aligned.
Worn band wheel
Too small band wheels
– try thinner bands
Chip brush
Check that the chip brush is properly adjusted and
change it regularly.
Band tension
The correct band tension is needed to get a straight cut.
Measure with the Bahco tensionmeter.
Band tension too high
Band tension too low
Bandsaw Blade
Cutting Data
Coolant/Cutting fluid
The coolant is needed to lubricate and to cool.
Check the concentration with a refractometer
Use a good coolant. It should reach the cut with
low pressure and with a generous flow.
Band speed
The band speed has to be correctly chosen,
see chart on page 8.
Check the band speed using the Bahco tachometer.
Feed rate
The feed rate has to be chosen so that the teeth of
the bandsaw blade can work properly, see page 8.
Tooth pitch
The selection of the right pitch of the blade is just as
important as choosing the correct feed and speed.
See page 9 and 10.
Workpiece
Feed rate too high
Feed rate too high
Tooth pitch too fine
Tooth pitch too fine
Tooth shape
Every tooth has its ideal application.
To select the right one, consult page 11.
Running in
A new bandsaw blade should be run in to obtain maximum
bandsaw tool life. (see page 7) Never saw in old kerf.
Blade life
All blades wear out eventually. Look for signs of wear.
30
Band speed too low
Surface
The surface quality of the workpiece will strongly
influence the life of the blade. If the surface is bad, lower
the band speed.
Clamping
Make sure the workpieces are securely clamped. This is
especially important when cutting bundles.
Do not use bent or damaged workpieces.
