Benchmark Abrasives 3-1/2" x 14 TPI bi-metal air saw blades provide a versatile coarse-pitch option for pneumatic reciprocating saws used in metalworking, automotive repair, fabrication, maintenance, and general cutting applications. With finer tooth spacing than the 10 TPI blade but a more aggressive pitch than the 18, 24, and 32 TPI options, 14 TPI provides a useful balance of cutting speed and tooth engagement across a range of materials.
Built with durable bi-metal construction, these compact scroll-style blades combine cutting performance with the flexibility required for reciprocating air saw operation. Each pack includes five blades, giving professional shops, fabricators, mechanics, and maintenance crews a practical replacement supply for compatible pneumatic air saws.

Features
14 TPI tooth pitch provides a versatile coarse cutting profile between the aggressive 10 TPI blade and finer 18, 24, and 32 TPI options.
Bi-metal construction combines cutting durability with the flexibility needed for reciprocating saw applications.
3-1/2" blade length is designed for compact pneumatic air saw and body saw applications.
Scroll-style profile supports controlled cutting in tight, curved, and detailed work areas.
Metal-cutting capability makes the blade useful for fabrication, automotive, exhaust, and maintenance applications.
Five-blade pack keeps replacement blades ready for shop and field use.
Available alongside 10, 18, 24, and 32 TPI options for matching tooth pitch to the material and application.
Applications
The 14 TPI blade provides a coarse-to-medium cutting option for applications that need more tooth engagement than 10 TPI while maintaining relatively aggressive cutting action.
Common applications include:
Automotive repair on suitable material thicknesses
Exhaust system cutting
Metal fabrication
Maintenance and repair
General shop cutting
Wood cutting
Fiberglass cutting
Plastic cutting
Pneumatic saw applications requiring a coarse tooth pitch
For thinner materials or applications requiring a finer cut, consider one of the higher-TPI options.
Materials
Bi-metal air saw blades are commonly used for cutting metal and non-metal materials, with blade pitch selected according to the material, thickness, and cutting application.
Suitable materials can include:
Mild steel
Sheet metal
Fabricated steel sections
Automotive body panels
Exhaust components
Aluminum
Other non-ferrous metals
Wood
Nail-embedded wood
Fiberglass
Plastic
The 14 TPI configuration provides finer tooth spacing than the 10 TPI blade while remaining coarser than the 18, 24, and 32 TPI options. As material becomes thinner, finer pitches are generally preferred to maintain more teeth in contact with the workpiece.
Machine Compatibility
Designed for compatible pneumatic reciprocating air saws and body saws.
Compatible Examples Include:
Ingersoll Rand® 429 Air Reciprocating Saw
Ingersoll Rand® 4429 Air Reciprocating Saw
Ingersoll Rand® 429G EDGE Series Air Saw
Ingersoll Rand® 529 Reciprocating Saw
Astro Pneumatic® 936 ONYX Gear Driven Heavy Duty Air Saw
AIRCAT® 6350 Low Vibration Air Saw
Astro Pneumatic® 930 Air Body Saber Saw
Astro Pneumatic® 129TW Air Saw
Astro Pneumatic® 929 Heavy Duty Industrial Air Saw
Always confirm blade length and mounting configuration with the requirements of your specific saw before installation.
Performance
The 14 TPI blade gives you more teeth per inch than 10 TPI while retaining a relatively open cutting pattern.
Match the pitch to the thickness being cut. For tubing, use wall thickness as your starting point when choosing TPI, and check overall blade reach separately.
The Benchmark 14 TPI blade is a fixed 14 TPI blade and should not be confused with 14/18 variable-pitch blades offered in some competing air saw blade systems.
Safety Tips
Disconnect the air supply before installing, removing, or changing the saw blade.
Follow the air saw manufacturer's instructions for proper blade installation and retention.
Make sure the blade is fully seated and securely retained before operating the saw.

Frequently Asked Questions
TPI means teeth per inch. This blade has 14 teeth per inch, giving it a coarser cutting profile than the 18, 24, and 32 TPI blades while providing finer tooth spacing than the 10 TPI option.
A 14 TPI blade is a versatile option when you want relatively aggressive cutting while maintaining more tooth engagement than a 10 TPI blade. As material becomes thinner, finer-pitch blades are generally preferred.
Yes. These bi-metal blades can handle suitable steel and non-ferrous metal sections in fabrication and repair work. For thin sheet metal and automotive body panels, consider 24 or 32 TPI.
Suitable applications can also include wood, nail-embedded wood, fiberglass, plastic when the material thickness and saw capacity suit the job.
No. This is a fixed 14 TPI blade. A 14/18 TPI blade uses a variable tooth pitch and is a different blade specification.
The blade uses bi-metal construction, providing a combination of cutting durability and flexibility for reciprocating air saw applications.
The nominal blade length is 3-1/2". Actual usable cutting reach depends on the saw's blade mounting position, guide, and stroke.
Each pack contains five blades.
These blades are designed for compatible pneumatic reciprocating air saws and body saws. Compatible examples include selected Ingersoll Rand®, Astro Pneumatic®, and AIRCAT® air saws. Confirm the mounting configuration and blade-length requirements of your specific tool before installation.
A finer pitch is generally preferred as metal becomes thinner because it keeps more teeth engaged in the cut. The 24 or 32 TPI options may be more appropriate when the application requires a finer tooth pitch.
