Product Description
CMT JS711DF-5 Reciprocating Saw Blades for Wood and Metal - BIM 6" x 6TPI (5-Piece Pack) are bi-metal sabre saw blades engineered to cut through wood with embedded nails, metal, chipboard, and glass fiber reinforced plastic in a single versatile blade. Built from BIM (bi-metal) construction with a 6 TPI tooth configuration and a total length of 6 inches, these blades handle demanding demolition and remodeling tasks where mixed materials are encountered. The pack of 5 ensures a ready supply for continuous jobsite use.
Key Features
- Bi-Metal (BIM) Construction - combines a high-speed steel cutting edge with a flexible backing so the blade resists breakage under stress while maintaining a sharp, durable tooth profile through wood-with-nails and metal applications.
- 6 TPI Tooth Configuration - the aggressive 6 teeth-per-inch pitch and 4.3mm tooth distance deliver fast, coarse cuts through thick mixed materials, reducing cut time and blade passes needed on site.
- 6" Total Length with 5-1/8" Cutting Height - a compact 6-inch overall length provides good reach into tight work areas while the 5-1/8 inch usable cutting height handles real-world material thicknesses with room to spare.
- 0.049" Tooth Thickness - precision-ground blade thickness minimizes kerf width, reducing material waste and keeping cuts controlled through chipboard and glass fiber reinforced plastic.
- Maximum Material Thickness up to 4" - rated for cutting wood with nails or metal in thicknesses less than 4 inches, making these blades suitable for structural lumber, pipe, framing, and demolition scenarios.
- 12mm Cutting Depth - the defined cutting depth spec ensures predictable blade engagement with the workpiece, giving operators confidence in blade performance across compatible materials.
- 5-Piece Pack Quantity - having 5 blades on hand means fewer work stoppages for blade changes during extended cutting sessions or multi-material projects.
Why This Product
- Cuts wood with embedded nails AND metal in a single blade - instead of stopping to swap blades when a nail or metal fastener is encountered in lumber, these BIM blades handle both materials, keeping demolition and remodeling work moving.
- Rated for material up to 4 inches thick - the less-than-4-inch maximum thickness rating covers a wide range of structural framing, dimensional lumber, and light metal stock encountered in renovation and construction work.
- Also cuts chipboard and glass fiber reinforced plastic - beyond wood and metal, compatibility with chipboard and GRP expands the blade's usefulness across trades including carpentry, electrical, and composite panel work.
- Pack of 5 blades included - the multi-pack format means a ready backup supply on the job, reducing the risk of a single worn blade halting progress mid-cut.

Frequently Asked Questions
What materials can the CMT JS711DF-5 blades cut?
These BIM blades are designed to cut wood with embedded nails or metal, chipboard, and glass fiber reinforced plastic. The maximum supported material thickness is less than 4 inches.
What does BIM mean and why does it matter for this blade?
BIM stands for Bi-Metal, a construction method that bonds a high-speed steel tooth edge to a flexible steel body. This combination gives the blade durability to cut through nails and metal while remaining flexible enough to resist snapping under the stress of reciprocating saw motion.
What is the usable cutting length of each blade?
Each blade has a total length of 6 inches and a cutting height of 5-1/8 inches, with a cutting depth of 12mm. This allows the blade to engage materials effectively within the rated thickness range.
Is a 6 TPI blade the right choice for my cut type?
A 6 TPI (teeth per inch) count with a 4.3mm tooth distance is suited for coarse, fast cuts through thick or dense mixed materials like wood with nails and metal. If your application involves thin sheet metal or fine finish work, a higher TPI blade would be more appropriate - but for demolition and general mixed-material cutting under 4 inches thick, 6 TPI is well-matched to the task.
