Product Description
CMT JS610VF-5 Reciprocating Saw Blades for Wood and Metal are bi-metal (BIM) demolition and rescue blades engineered for aggressive cutting through wood with nails, metal, chipboard, glass fibre reinforced materials, and mixed-material wall cutouts. Sold in a 5-piece pack, these 6-inch blades feature a variable 5-8 TPI progressive tooth pattern that transitions smoothly between coarse and finer cuts, allowing a single blade to handle the unpredictable mix of materials encountered during demolition, remodeling, and rescue operations. With a maximum cutting capacity of under 4 inches in thickness and a cutting height of 5-1/8 inches, these sabre saw blades deliver reliable performance across a wide range of reciprocating saw applications.
Key Features
- Bi-Metal (BIM) Construction - high-speed steel teeth are bonded to a flexible spring-steel body, combining hardness at the cutting edge with resistance to breakage under the lateral stress of demolition work, extending blade life significantly compared to carbon-steel alternatives.
- Variable 5-8 TPI Progressive Tooth Pattern - the graduated tooth spacing transitions from aggressive 5 TPI coarse cutting to a finer 8 TPI finish, enabling a single blade to move through both soft wood framing and embedded nails or thin metal without swapping blades mid-cut.
- 0.063-inch Tooth Thickness - the heavy tooth profile resists deflection and tooth stripping when the cutting edge encounters hard inclusions like nails, fasteners, or metal framing during rescue and demolition passes.
- 6-inch Total Length with 5-1/8-inch Cutting Height - delivers deep reach into wall cavities, floor assemblies, and structural panels, keeping the saw body clear of the work surface during angled and flush cuts.
- Maximum Material Thickness Under 4 Inches - rated for materials up to 4 inches thick, covering common dimensional lumber, doubled framing members, metal studs, chipboard panels, and glass fibre reinforced composites in a single plunge.
- Optimized for Rescue and Demolition Work - the 3.2-5 mm tooth distance and BIM construction are specifically selected for the unpredictable, high-impact demands of emergency cutting and structural tear-out, where blade failure is not an option.
- 5-Piece Pack - multiple blades are included so crews can rotate fresh blades on extended demolition jobs without interruption, keeping productivity high across long-duration projects.
Why This Product
- When cutting through walls or floors that contain an unknown mix of wood framing, embedded nails, and metal fasteners, the BIM variable-TPI design handles all of these in a single pass - eliminating the downtime of stopping to change blades between materials.
- The 22 mm cutting depth and under-4-inch maximum material thickness rating make these blades a practical match for the doubled lumber, laminated panels, and composite assemblies common in remodeling and structural demolition projects.
- Glass fibre reinforced materials and chipboard are abrasive enough to destroy carbon-steel blades rapidly - the bi-metal BIM construction maintains cutting performance across these demanding materials far longer, reducing per-cut blade cost on volume jobs.
- Buying in a 5-piece set means demolition and rescue teams always have a fresh blade ready, avoiding single-blade shortages on job sites where stopping work to source a replacement is not practical.

Frequently Asked Questions
Can these blades cut through wood that contains embedded nails or screws?
Yes. The bi-metal (BIM) construction is specifically designed for cutting wood with nails. The high-speed steel teeth resist dulling and breakage when the blade contacts embedded fasteners, making these a reliable choice for demolition and rescue applications where mixed materials are common.
What is the maximum material thickness these blades can handle?
These blades are rated for materials under 4 inches in maximum thickness, covering most common applications including doubled dimensional lumber, metal framing, chipboard panels, and glass fibre reinforced composites encountered in demolition and structural work.
What does the variable 5-8 TPI tooth pattern mean in practice?
The progressive TPI rating means the tooth spacing varies across the blade - from 5 TPI (coarser, faster cutting) to 8 TPI (finer, more controlled cutting). This graduated pattern allows a single blade to transition between different materials and densities without requiring a blade change, which is a significant advantage during rescue and demolition work where materials are unpredictable.
Are these blades compatible with standard reciprocating saws?
These are standard sabre saw blades. The blade class (JSR) is designed for use with reciprocating saws. Consult your tool's manual to confirm shank compatibility before use.
