6" x .035" x 18T Bi-Metal Reciprocating Blade - 10 Pack

6" X .035" 18 TPI BI-METAL RECIPROCATING SAW BLADES - 10 PACK

The Benchmark Abrasives 6" x .035" x 18T bi-metal reciprocating blade is a professional-grade blade designed for clean, controlled cutting in metal and fiberglass. Its heavy-duty bi-metal construction combines a flexible, heat-treated spring-steel alloy backing with cobalt high-speed steel cutting teeth, helping the blade absorb vibration and shock while maintaining a durable cutting edge through demanding reciprocating-saw applications.

The cobalt teeth are electron welded to the flexible backing for a strong, long-lasting bond, while computer-designed tooth geometry supports accurate tooth setting and consistent cutting performance. A white painted finish adds resistance to wear, abrasion, and corrosion. At 18 TPI, this blade is optimized for clean, fast cuts in thinner metal selection up to approximately 1/4" thick, as well as fiberglass.

Product Specifications

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 cutting performance.
• 18 TPI configuration provides clean cutting and controlled tooth engagement in thinner metal sections.
• 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 18 TPI tooth configuration is designed for finer cutting applications where clean edges, controlled cutting, and consistent tooth engagement are important.

Recommended applications include:

• Metal cutting
• Sheet metal
• Sheet and light metal sections
• Metal up to approximately 1/4" thick
• Fiberglass
• General fabrication
• Maintenance and repair

Materials

Suitable materials include:

• Ferrous metals
• Non-ferrous metals
• Fiberglass

For thicker metal sections, a 14 TPI Benchmark Abrasives reciprocating blade may provide a faster cutting rate. For thinner sheet metal and conduit, a 24 TPI blade may provide better tooth engagement and a finer cut.

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.

18 TPI Performance

An 18 TPI blade uses a finer tooth pitch to keep more teeth engaged with thinner material during the cut. This helps reduce snagging and supports a cleaner, more controlled cut than coarser-pitch blades.

Compared with 14 TPI, the 18 TPI configuration is better suited to thinner metal sections. Compared with 24 TPI, it maintains a stronger balance between cutting speed and finish quality in metals up to approximately 1/4" thick. 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.
• Keep multiple teeth engaged when cutting metal; choose TPI by wall thickness when cutting pipe or conduit.
• Do not bend, twist, or excessively 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.
