4" x .035" x 14T Bi-Metal Reciprocating Blade - 10 Pack

The Benchmark Abrasives 4" x .035" x 14T bi-metal reciprocating blade is a professional-grade blade built for clean, efficient cutting in wood, PVC, and metal applications. Its heavy-duty bi-metal construction combines a flexible, heat-treated spring-steel alloy body with cobalt high-speed steel cutting teeth, helping the blade absorb vibration and shock while maintaining a durable cutting edge.

The cobalt teeth are electron welded to the backing for a strong bond, while computer-designed tooth geometry supports consistent tooth setting and precise cutting action. A white painted finish adds resistance to abrasion, wear, and corrosion. At 14 TPI, this blade is designed for clean, fast cuts in wood, PVC pipe, and metal up to approximately 1/2" thick.

Features

• Professional-grade, heavy-duty bi-metal construction for demanding cutting applications.
• Flexible spring-steel alloy backing helps absorb vibration and resist shock and breakage.
• Electron-welded cobalt high-speed steel teeth provide a durable cutting edge.
• Computer-designed tooth geometry supports accurate tooth setting and consistent performance.
• 14 TPI configuration provides a cleaner cut than coarse demolition-style blades while maintaining efficient material removal.
• White painted surface provides additional resistance to abrasion, wear, and corrosion.
• 1/2" universal tang is designed for standard reciprocating saw blade holders.

Applications

The 14 TPI tooth configuration is a versatile intermediate pitch suited for cleaner cutting in both general-purpose and metalworking applications.

Recommended applications include:

• Wood cutting
• PVC pipe
• Metal cutting up to approximately 1/2" thick
• General construction and maintenance
• Repair work
• Fabrication applications

Materials

Suitable materials include:

• Wood
• PVC
• Ferrous metals
• Non-ferrous metals

For thinner sheet metal and conduit, a finer 18 TPI or 24 TPI Benchmark Abrasives reciprocating blade may provide a better tooth engagement and finish.

Machine Compatibility

The 1/2" universal tang shank is designed for standard reciprocating saw blade machines,

Compatible examples include:

• Milwaukee® M18 FUEL™ SAWZALL®2821-20
• Milwaukee®M12™ HACKZALL® 2420-20
• Bosch®GSA 1100 E
• Astro Pneumatic® ONYX 936 air saw
• Other reciprocating saws with a standard 1/2" universal-shank holder

Choose a blade long enough to clear the shoe and workpiece throughout the full stroke, and stay within your saw's cutting capacity. Compact air saws with a different blade mount require their specified blades.

14 TPI Performance

A 14 TPI blade offers a strong balance between cutting speed and finish quality, making it a practical choice for users who need one blade for a range of wood, PVC, and metal cutting tasks.

Compared with a 10 TPI blade, the finer tooth pitch provides more teeth in contact with the workpiece for a smoother cut. Compared with 18 TPI or 24 TPI blades, it maintains a more aggressive cutting rate in thicker material. For pipe and conduit, choose TPI by wall thickness and blade length by the full outside dimension.

Safety Tips

• Always wear appropriate eye, hearing, and hand protection.
• Unplug the saw, remove the battery, or disconnect the air supply before changing blades.
• Confirm the blade is fully seated and securely locked in the saw's blade holder before operation.
• Select a blade long enough to extend beyond the shoe and workpiece throughout the saw's complete stroke.
• Secure the workpiece before cutting.
• Do not bend, twist, or side-load the blade during use.
• Replace blades showing excessive tooth wear, cracks, deformation, or other damage.
• Follow all operating and safety instructions supplied with your reciprocating saw.
