Blade Construction
Carbon Blades
Hard Back type:
A one-piece blade made of carbon steel with a
hardened back and tooth edge.
Flex Back type:
A one-piece blade
made of carbon steel with a hardened tooth edge and soft back.
Bi-metal Blades
A high speed steel edge material is electron beam welded to fatigue resistant spring steel backing. Such a construction provides the best combination of cutting performance and fatigue life.
Carbide Ground Tooth Blades
Teeth are formed in a high strength spring steel alloy backing material.
Carbide is bonded to the tooth using a proprietary welding operation. Tips are then side, face and top ground to form the shape of the tooth.
Set Style Carbide Tooth
Teeth are placed in a high strength spring alloy backing material. Carbide is bonded to the tooth and ground to form the shape of the tooth. The teeth are then set, providing for side clearance.

NOTE:
When using a WOOD Cutting band saw for cutting metal (saw running about
3000 BFPM) hardened metal will not be able to be cut. Bandsaw blade
speeds between 75 and 300 BFPM are required to cut hardened materials
and receive favorable blade life. If your wood saw has two speeds, use
the slow speed for cutting soft metal.
When cutting wood, the Rule of Thumb is 3 to 12 teeth in the work, with the most general purpose count being 6 TPI. The fewer teeth per inch provide a faster, but rougher cut; and more teeth per inch provide a smoother, but slower cut. When resawing use the widest blade suitable for your saw with the fewest number of teeth per inch. Make sure that you select a blade of proper thickness. The continual flexing of the blade causes metal fatigue and failure of the blade. Fatigue is the tendency of a metal to break under continued flexing. The thickness of the blade required depends upon the diameter of the wheels and the work to be done. Thick blades will withstand more strain from cutting than thin blades, but will break more easily from the bending action, especially when run on small wheels. Each revolution flexes the blade to near the elastic limit of the steel, which causes the metal to fatigue and break quickly. Thinner blades are recommended when the work is light.

Bandsaw Blade Terms
A clear understanding of blade terminology can help avoid confusion when discussing cutting problems.
-
1. Blade Back - The body of the blade not including tooth portion.
2. Gauge - The thickness of the blade.
3. Width - The nominal dimension of a saw blade as measured from the tip of the tooth to the back of the band.
4. Set - The bending of teeth to right or left to allow clearance of the back of the blade through the cut.
5. Tooth - The cutting portion of a saw blade.
6. Tooth Pitch - The distance from the tip of one tooth to the tip of the next tooth.
7. TPI - The number of teeth per inch as measured from gullet to gullet.
8. Gullet - The curved area at the base of the tooth. The tooth tip to the bottom of the gullet is the gullet depth.
9. Gullet Depth - The distance from the tooth tip to the bottom of the gullet.
10. Tooth Face - The surface of the tooth on which the chip is formed.
11. Tooth Back - The surface of the tooth opposite the tooth face.
12. Tooth Back Clearance Angle - The angle of the tooth back measured in relation to the cutting direction of the saw.
13. Tooth Rake Angle - The angle of the tooth face measured with respect to a line perpendicular to the cutting direction of the saw.
14. Tooth Tip - The cutting edge of the saw tooth.
15. Kerf - Amount of material removed by the cut of the blade.
BAND SPEED
The rate at which the band saw blade moves
across the work to be cut. The rate is usually measured in feet per
minute (fpm) or meters per minute (mpm).
BASE BAND SPEED
List of recommended speeds for cutting
various metals, based on a 4" wide piece of that stock.
BI-METAL
A high speed steel edge material electron
beam welded to a spring steel back. Such a construction provides the
best combination of cutting performance and fatigue life.
BLADE WIDTH
The dimension of the band saw blade from
tooth tip to blade back.
CARBIDE
TIPPED BLADE
Carbide tips welded to a high-strength
alloy back, resulting in a longer lasting, smoother cutting blade.
CARBON FLEX BACK
A solid one-piece blade of carbon
steel with a soft back and a hardened tooth, providing longer blade
life and generally lower cost per cut.
CARBON HARD BACK
A one-piece blade of carbon steel
with a hardened back and tooth edge that can take heavier feed
pressures, resulting in faster cutting rates and longer life.
CUTTING RATE
The amount of material being removed over
a period of time. Measured in square inches per minute.
DEPTH OF PENETRATION
The distance into the material
the tooth tip penetrates for each cut.
Tooth Form and Construction
As with a bi-metal blade design, there are advantages to differing tooth constructions. The carbide tipped tooth has carbide tips welded to a high strength alloy back. This results in a longer lasting, smoother cutting blade.
Tooth Form
The shape of the tooth’s cutting edge affects how efficiently the blade can cut through a piece of material while considering such factors as blade life, noise level, smoothness of cut and chip carrying capacity.
Variable Positive - Variable tooth spacing and gullet capacity of this design reduces noise and vibration, while allowing faster cutting rates, long blade life and smooth cuts.
Variable - A design with benefits similar to the variable positive form for use at slower cutting rates.
Standard - A good general purpose blade design for a wide range of applications.
Skip - The wide gullet design makes this blade suited for non-metallic applications such as wood, cork, plastics and composition materials.
Hook - Similar in design to the Skip form, this high raker blade can be used for materials which produce a discontinuous chip (such as cast iron), as well as for non-metallic materials.
Tooth Set
The number of teeth and the angle at which they are offset is referred to as "tooth set." Tooth set affects cutting efficiency and chip carrying ability.
Raker:
3 tooth sequence with a uniform set angle (Left, Right, Straight).
Modified Raker:
5 or 7 tooth sequence with a uniform set angle for greater cutting efficiency and smoother surface finish (Left, Right, Left, Right, Straight). The order of set teeth can vary by product.
Vari-Raker:
The tooth sequence is dependent on the tooth pitch and product family. Typically Vari-Raker set provides quiet, efficient cutting and a smooth finish with less burr.
Alternate:
Every tooth is set in an alternating sequence. Used for quick removal of material when finish is not critical.
Wavy:
Groups of teeth set to each side within the overall set pattern. The teeth have varying amounts of set in a controlled pattern. Wavy set is typically used with fine pitch products to reduce noise, vibration and burr when cutting thin, interrupted applications.
Vari-Set:
The tooth height / set pattern varies with product family and pitch. The teeth have varying set magnitudes and set angles, providing for quieter operation with reduced vibration. Vari-Set is efficient for difficult-tocut materials and larger cross sections.
Single Level Set:
The blade geometry has a single tooth height dimension. Setting this geometry requires bending each tooth at the same position with the same amount of bend on each tooth.
Dual Level Set:
This blade geometry has variable tooth height dimensions. Setting this product requires bending each tooth to variable heights and set magnitudes in order to achieve multiple cutting planes.
Selecting Bandsaw Blade Width, Thickness and TPI

Choosing the Correct Bandsaw Blade Width
Blade width is measured from the tips to the teeth to the back edge of the blade body.
The instructions for the particular bandsaw being used should be followed when selecting blade width.
If no such instructions exist, the blade width should be determined with the following guidelines:
Cut-Off Sawing (Re-sawing)
The blade selected should be as wide as the machine will allow, keeping in mind the blade thickness and wheel diameter.
The wider the bandsaw blade is, the straighter the cut will be.
The bandsaw blade should be as wide as the machine allows,
but still narrow enough so that it can cut the desired shape (radius).
Minimum dimensions for different cutting radii are shown in the radius chart
How to Choose the Correct Number of Teeth Per Inch (TPI)
The number of teeth per inch (TPI) is important in obtaining the finish desired and the proper feed rate. A coarse tooth blade (2, 3 TPI) should be used for re-sawing wood and cutting thicker stock up to 8" thick. A fine toothed blade (18 to 32 TPI) should be used for thinner metals and plastics under 1/4". For general cutting of 3/4" plywood 6 TPI will provide a fast cut and 14 TPI will cut much slower but leave a smooth finish on the cut.
When Selecting TPI Remember:
- More TPI gives a smoother but slower cut.
- Fewer TPI allows for a faster cut with a slightly rougher cut surface.
- Should have at least 3 teeth and less than 12 teeth in the work piece.
Band Saw Blade Thickness
The thickness of a bandsaw blade is determined by the thickness of the blade body. Bandsaw blades vary in thickness .014", .018", .020", .022", .025", .032", .035", .042", .050", .063".
Make sure that you select a blade of proper thickness. The continual flexing of the blade causes metal fatigue and failure of the blade. Fatigue is the tendency of a metal to break under continued flexing.
The thickness of the blade required depends upon the diameter of the wheels and the work to be done. Thick blades will withstand more strain from cutting than thin blades, but will brake more easily from the bending action, especially when run on small wheels. Each revolution flexes the blade to near the elastic limit of the steel, which causes the metal to fatigue and brake quickly. Thinner blades are recommended when the work is light.

It is not always possible to adhere to the above recommendations due to the cutting operation you intend to perform and the particular band saw you are using. To maintain extended fatigue life of the blade, select the thinnest blade possible that will offer you the appropriate number to TPI to perform you cutting operation.
- Fewer TPI allows for a faster cut with a slightly rougher cut surface.
