3-1/2" x 32T Air Saw Blade - 5 Pack

3-1/2" X 32 TPI BI-METAL AIR SAW BLADE - 5 PACK

Benchmark Abrasives 3-1/2" x 32 TPI bi-metal air saw blades are built for fine, controlled cutting in pneumatic reciprocating saw applications. With the highest density count in our 3-1/2" air saw blade range, the 32 TPI configuration provides the finest tooth spacing of the 10, 14, 18, 24, and 32 TPI options, making it especially well suited to thinner materials and applications where increased tooth engagement is important.

Constructed from durable bi-metal, these compact scroll-style blades combine cutting performance with the flexibility required for reciprocating air saw operation. Supplied in a 5-pack, they are a strong choice for automotive bodywork, sheet metal, fabrication, maintenance, and other precision cutting applications using compatible pneumatic air saws.

Product Specifications

Features

• Fine 32 TPI tooth pitch provides the highest tooth density in the Benchmark Abrasives 3-1/2" air saw blade range.
• 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 confined, curved, and detailed work areas.
• Fine metal-cutting capability makes the blade well suited to thin sheet, automotive bodywork, fabrication, and maintenance applications.
• Five-blade pack provides convenient replacement stock for professional shop and field use.
• Available alongside 10, 14, 18, and 24 TPI options for matching tooth pitch to the material and application.

Applications

The 32 TPI blade is the finest-pitch option in the Benchmark Abrasives air saw blade lineup and is intended for applications that benefit from finer tooth spacing and controlled 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 thicker sections or applications where more aggressive tooth spacing is preferred, consider one of the lower-TPI options.

Materials

Bi-metal air saw blades are commonly used for cutting metal as well as non-metal materials, with the correct tooth pitch selected according to material type, section thickness, and cutting application.

Suitable materials can include:

• Mild steel
• Thin sheet metal
• Automotive body panels
• Thin-wall steel sections
• Exhaust components
• Aluminum
• Other non-ferrous metals
• Fiberglass
• Plastic
• Wood
• Nail-embedded wood

The 32 TPI configuration provides the finest tooth spacing in the Benchmark Abrasives range, helping keep more teeth engaged in thinner materials. For thicker sections, a lower-TPI blade may provide more appropriate tooth spacing and more aggressive cutting action.

Performance

The 32 TPI blade has the finest tooth spacing in this range, making it a strong choice for thin sheet and detailed bodywork.

In general, finer pitches help maintain tooth engagement in thin materials, while coarser pitches are better suited to thicker sections where wider tooth spacing is beneficial. Selecting the proper TPI for the material and thickness helps improve cutting control, tooth engagement, and blade performance.

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.
• Wear appropriate eye and face protection during cutting.
• Secure the workpiece before beginning the cut.
• Keep hands and other body parts clear of the blade and cutting path.
• Do not use a damaged, bent, or improperly mounted blade.
• Confirm the blade and saw are appropriate for the material being cut.
• Operate the saw only within the manufacturer's stated limits.
