Product Overview
Band Saw Blades｜Material and TPI Selection Guide
This band saw blade series offers multiple material options, including carbon steel, bi-metal, and M42 high-performance bi-metal blades. Available tooth pitches include 10, 14, 18, and 24 TPI fixed pitch, as well as 10/14 and 14/18 TPI variable pitch. Blades can be selected according to workpiece material, thickness, shape, and cutting conditions, making them suitable for metal cutting, pipe cutting, profile cutting, repair work, and general workshop applications.
Material Options
Carbon steel, bi-metal, M42 high-performance bi-metal
Fixed Pitch
10, 14, 18, 24 TPI
Variable Pitch
10/14, 14/18 TPI
Main Applications
Metal cutting, pipe cutting, profile cutting, bundle cutting, and repair work
Selection Factors
Workpiece material, thickness, shape, band saw machine specification, and cutting speed
Blade selection is not only about material; tooth pitch and workpiece thickness are equally important
TPI means teeth per inch. In general, thicker workpieces require coarser tooth pitch, while thinner workpieces require finer tooth pitch. For pipes and hollow profiles, selection should be based on the actual wall thickness at the cutting point and the number of teeth in contact, not only on outside diameter.
Blade Materials
Blade Material Options
Different blade materials are suitable for different cutting conditions. Carbon steel blades are suitable for general and economical cutting. For better durability, fatigue resistance, and metal cutting performance, bi-metal or M42 high-performance bi-metal blades can be selected according to workpiece strength.
Carbon Steel
Carbon Steel Blade
Offers good toughness and economy. Suitable for general cutting and materials that are easier to machine. Depending on specification, it may also be used for plastics, composites, and wood cutting.
Bi-Metal
Bi-Metal Blade
Combines high-speed steel teeth with a tough alloy steel back, offering both cutting performance and fatigue resistance for general metalworking and higher-frequency cutting.
M42
M42 High-Performance Bi-Metal Blade
Uses M42 high-speed steel tooth tips with better heat resistance, wear resistance, and impact resistance, making it suitable for higher-strength or more difficult-to-cut metal materials.
TPI Selection
Tooth Pitch and Selection Method
Both fixed pitch and variable pitch options are available. Fixed pitch is suitable for workpieces with uniform thickness and stable cutting conditions. Variable pitch covers a wider thickness range and is suitable for pipes, profiles, and materials with varying cross sections.
Fixed Pitch
Consistent tooth spacing, suitable for uniform-thickness workpieces and stable cutting conditions
Variable Pitch
Alternating tooth pitches, such as 10/14 TPI, suitable for pipes, profiles, and varying cross sections
Coarse Pitch
Suitable for thicker workpieces, helping improve chip clearance and reduce tooth clogging
Fine Pitch
Suitable for thinner workpieces, helping maintain smoother cutting and better cut quality
For pipes, profiles, and hollow materials, do not select TPI by outside diameter alone
When cutting pipes or hollow profiles, the real load on the teeth is affected by actual wall thickness, the number of teeth in contact, and cross-section shape. Selecting TPI only by outside diameter may lead to tooth skipping, material catching, tooth breakage, or unstable cutting efficiency.
Recommended Thickness
Recommended Cutting Thickness
The following TPI and workpiece thickness guide can be used as an initial selection reference. Actual selection should still consider material type, workpiece shape, band saw machine specification, and cutting speed.
10 TPI
7.9–12.7 mm
14 TPI
4.7–7.9 mm
18 TPI
3.9–4.7 mm
24 TPI
Below 3.9 mm
10/14 TPI
4.7–12.7 mm
14/18 TPI
3.9–7.9 mm
Recommended thickness is a starting point, not the only selection rule
In actual cutting, harder materials, variable cross sections, bundle cutting, or insufficient machine rigidity may require adjustments to tooth pitch, feed rate, or cutting speed to achieve stable cutting quality and blade life.
Applications
Applications
Depending on blade material and tooth pitch, these blades can be used for carbon steel, alloy steel, stainless steel, non-ferrous metals, cast iron, plates, round bars, pipes, profiles, and general metal cutting applications.
Steel and Stainless Steel Cutting
Suitable for cutting carbon steel, alloy steel, and stainless steel materials. Blade material should be selected according to workpiece strength.
Non-Ferrous Metal Processing
Suitable for cutting aluminum, copper, brass, and other non-ferrous metals.
Round Bar and Solid Materials
Can be used for cutting cast iron, plates, round bars, and solid materials.
Pipes and Structural Profiles
Suitable for steel pipes, thin-wall pipes, angle steel, and structural profiles with different cross sections.
Bundle Cutting and General Processing
Can be used for bundle cutting and general metal cut-off work depending on tooth pitch and machine conditions.
Workshop and Repair Work
Suitable for mold shops, machine shops, equipment repair, and on-site fabrication work.
Actual selection requires combined judgment
When selecting a band saw blade, consider workpiece material, thickness, shape, band saw machine specification, and cutting speed together to achieve more stable cutting quality and longer blade life.
