CMT JS5678XF-5 Reciprocating Saw Blades for Wood and Metal - BIM 9" x 6-12 TPI (5-Piece) are bi-metal demolition blades engineered for versatile cutting through demanding materials including wood with nails, sheet metal, aluminum profiles, chipboard, and glass fiber-reinforced plastic or epoxy. The progressive 6-12 TPI tooth pattern transitions smoothly between coarse and finer cutting, reducing blade chatter and improving cut quality across mixed materials in a single pass. Sold as a 5-piece set, these sabre-style reciprocating blades are a practical choice for remodeling, demolition, and fabrication work where material types vary.

Key Features

• Bi-Metal (BIM) Construction - combines a flexible spring-steel body with hardened high-speed steel teeth, allowing the blade to flex under load without snapping while maintaining a sharp cutting edge through tough materials including nails and metal fasteners embedded in wood.
• Progressive 6-12 TPI Tooth Pattern - the variable tooth geometry transitions from aggressive coarse cutting to finer finishing within a single blade stroke, reducing vibration and improving surface quality when cutting through layered or mixed materials.
• 9" Total Length with 8" Cutting Height - the extended blade length provides deep reach into workpieces, making it well suited for demolition cuts through thick framing members, chipboard panels, and composite materials up to 6-57/64" (175mm) in thickness.
• 0.05" Blade Tooth Thickness - the precise tooth geometry supports accurate kerf control, reducing material waste and helping maintain a consistent cutting path through aluminum profiles ranging from 3mm to 18mm (1/8" to 3/4") in thickness.
• Cuts Glass Fiber-Reinforced Plastic and Epoxy - the BIM tooth construction resists the abrasive wear caused by fiberglass and epoxy composites, extending blade life in applications where standard carbon steel blades would dull rapidly.
• 5-Piece Pack - having multiple blades on hand reduces downtime on the job site, ensuring a fresh blade is always available when cutting demanding materials that accelerate tooth wear.

Why This Product

• When demolition or remodeling work involves unpredictable material combinations - wood framing with embedded nails, sheet metal, or composite panels - this blade handles all of them without requiring a blade swap, saving time on the job.
• The 9" length and 8" cutting height give contractors the reach needed to cut through thick chipboard or wood assemblies up to 175mm (6-57/64") without repositioning, making deep demolition cuts more efficient.
• For work involving aluminum profiles from 1/8" to 3/4" thick alongside wood or fiberglass substrates, the progressive TPI design adapts to varying densities in a single cut, reducing the need for multiple specialized blades.
• Purchasing in a 5-piece set means replacement blades are immediately available when cutting abrasive materials like glass fiber-reinforced plastic or epoxy that wear teeth faster than standard wood cuts.
