carbide-tipped products such as the 3860 TMC. Or are you more of a general purpose cut shop, cutting a wide variety of materials, shapes and sizes? Our unique 3857 Easy-Cut ensures long blade life
and fewer blade changes.
Quality. Consistency. Bahco strives to maintain the quality of its products and deliver cost per cut savings
consistently. We do so by operating in a quality forward system, using the ISO 9001-2000 framework. We
take a Rapid Continuous Improvement (RCI) approach to our production processes, which reflects in the
quality and performance of our product.

General Information
Precision tools you can rely on:
Quality is our number one priority and we also believe that a key factor in both production cutting and
general purpose cutting is product consistency. To achieve this, we operate within Bahco’s quality
forward system, which uses the ISO 9001-2000 framework. We strive to continually improve our
quality management system focusing on customers’ needs and satisfaction.
Tooth Forming
High technology milling and grinding processes
are used for precision tooth forming, enabling the
production of sharper and stronger teeth.
Carbide Fusion Welding
•High consistancy in carbide tip positioning
•Stong bonding elimnates tooth strippage.
All finished products are deliveried to our highly
automated distribution centers.
Setting
Computer controlled measuring devices and
camera monitoring systems check every tooth. This
information is collated and displayed on a monitor
which:
•Measures the set against the permissible tolerance,
triggering an automatic shut-off in case of deviation
•Ensures a highly consistent set
•Provides a report card for every coil
•Creates a permanent record in our quality data base

Blades are designed exclusively for general
purpose sawing in tool rooms, machine shops,
maintenance rooms, fabricating shops and
welding shops.
Bahco’s perfect “recipe” combines the science
of rake angle, unique patented tooth geometry
& M42 high speed steel material to produce the
tough, resilient and versatile Easy-Cut® blade.
• Tool Steel
• Mild Steel

• Copper
• Brass
Easy to order – simply specify blade width
and length. The unique patented tooth design
cuts any shape or size in virtually any material,
while eliminating the need to specify pitch or
tooth form.

design and M-42 tooth tips combine to create
a blade that lasts longer and will not strip teeth
like other blades, allowing the operator to spend
more time cutting and less time changing saw
blades.
Easy to decide – save time and money by
reducing blade inventory, operator labor, and
machine down time.

Technical Information
3870-Bandcalc is an interactive computer software program,
available on CD, that quickly determines the best blade for
a specific applicaiton, based on the user’s requirements, the
material to be cut, the machine, workpiece etc.
Simply select the blade, and information on blade speed and
fee-rate will be supplied. It is a an excellent tool for anyone
looking to improve efficiency. It also calculates the cost per
cut for you, taking into consideration all factors, including the
machine cost.
Feed Rate/Chips
a.
It is important that each tooth of the bandsaw blade cuts a chip with
the right thickness.
This is determined by the selection of tooth pitch, band speed and
feed rate.
x
1: Start by selecting the correct tooth pitch from the selection charts.
2: Then set your band speed and feed rate according to BANDCALC.
b.
3: Once cutting, you can adjust the feed rate by studying the chips that the saw is producing.
4. Compare them to the diagrams below.
a. Thin or pulverized chips – increase feed or decrease band speed
b. Loosely rolled chips – correct
c. Thick, heavy, or blue chips – decrease feed rate or
increase band speed

Technical Information
Chip Load Per Tooth Formula
HEIGHT OF CUT (INCHES)
(12 X AVE. TPI) X SFPM X CUT TIME
= CHIP LOAD
Use your specific cutting data to apply a numeric value to your chip size.
•
HEIGHT OF CUT: height of the material being cut in inches
•
AVE. TPI: average teeth per inch, multiplied by 12. If the blade you are using has a 2/3 pitch, your average TPI is 2.5. 2.5 X 12 = 30
•
SFPM: surface feet per minute, or the speed at which the blade is traveling.
Most bandsaws read blade speed as SFPM.
•
CUT TIME: How long it takes to cut the workpiece, in minutes.
For example, if your cut takes 4 minutes, 30 seconds, enter 4.5 minutes.
You can now compare your chip load to this list of common “target” chip loads,
depending on your material:

Technical Information
Tooth Pitch Selection Charts
Solid workpieces
The diagram will help you select the right pitch
for cutting solids.
hen cutting a 6 inch (150 mm) bar,
Example 1: W
use 2 TPI, if an evenly pitched blade
is your choice. Use a 2/3 TPI or a
1.4/2 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.
Cutting Pipes and Profiles
The diagram will help you select the right pitch
for cutting pipes and profiles.
The recommended tooth pitch for cutting profiles
is found in the field where with width meets the
wall thickness of the profile.
Example 3: W
hen cutting a 4” x 3/8” I-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 thickneess
of the pipe to be cut.
Example 2: W
hen cutting a 1-1/2” x 1/16” pipe,
select a 10/14 TPI blades.

Technical Information
Bandsaw Blade Width
Blade Break In - Bimetal
The band width is measured from the tip of the
teeth to the back edge of the blade.
To obtain the maximum blade life always use the
recommended band speed but lower the feed rate
to 1/3-1/2 during the first 10 minutes of cutting.
Bandsaw Blade Tooth Set
During the next 10 minutes increase the feed rate
in stages, until you have reached the recommended
feed rate.
The set is the tilt, or angle, given to the teeth of the
saw blade to provide clearance for the blade body
and the tooth edges.
Blade Break In - Carbide
When breaking in Carbide blades start at normal
Bimetal speeds and feeds and work up to nominal
chip load. (Refer to page 22).
Teeth Per Inch (TPI) r inch
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, i.e. fewer teeth per inch. The fewer
teeth engaged in the workpiece the higher the cutting capacity. This is because the penetration
capacity of each individual tooth is greater if the
saw’s feed pressure is distributed over a fewer number of teeth. Therefore, a coarse pitch blade
(few TPI) increases productivity and provides the
desired large chip space.
Soft materials, such as aluminium and bronze,
require a large chip space. A coarse pitch prevents the chips from building up and packing
together in the gullets, which can impair sawing
and damage the blade. Use the TPI selection
guides to find the right pitch for your application.
Do not break-in 3881 THS (see page 18) or 3868
TSS (see page 16), these products are run-in at the
factory.
Bandsaw Machine Tips
Check frequently:
•The operation of the chip brush.
•The wear and alignment of the guides.
•The band tension with a tensionmeter
(see page 27).
•The band speed with a tachometer (see page 27).
•The coolant concentration with a refractometer
(see page 27).
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 low pressure and large flow.
Workpiece
•Make sure that the workpiece is firmly clamped so
that it cannot vibrate or rotate.
•Do not use bent or damaged workpieces.
WARNING
• Wear Safety Goggles
• Wear hearing protection •Avoid prolonged exposure
(users and bystanders) (users and bystanders) to vibration.
