Product Description
CMT JS1210VF-5 Reciprocating Saw Blades for Wood and Metal are 12-inch bi-metal (BIM) sabre saw blades engineered for demanding rescue and demolition work, delivering aggressive cutting performance through wood with nails, metal, chipboard, and glass fibre reinforced materials. Sold as a 5-piece pack, these variable-tooth blades combine a 5-8 TPI tooth pattern with a robust BIM construction to handle thick stock - up to 10 inches - in a single versatile blade designed for professionals who cannot afford to stop and change blades mid-job.
Key Features
- Bi-Metal (BIM) Construction - the high-speed steel teeth bonded to a flexible backing provide superior wear resistance and extended cutting life compared to carbon-steel-only blades, reducing how often you need to stop and swap blades during demolition or rescue operations.
- Variable 5-8 TPI Tooth Pattern - the progressive tooth spacing adapts to both coarser wood cuts and finer metal cuts in a single blade, so you can move between mixed materials without reaching for a second blade.
- 12-Inch Total Length with 11-Inch Cutting Height - the generous cutting reach lets you work through thick assemblies and embedded materials, giving you access in tight or deep wall cutouts where shorter blades fall short.
- Maximum Cutting Capacity up to 10 Inches Thick - handles full-depth cuts through thick wood-and-nail combinations, chipboard, and glass fibre reinforced panels, making this blade appropriate for structural demolition as well as rescue applications.
- 3.2-5mm Tooth Distance - the wider gullet spacing clears chips and debris efficiently, keeping the cut fast and reducing heat buildup when working through abrasive or composite materials.
- 0.063-Inch Blade Thickness - the blade body is thick enough to resist flex and deflection under load, keeping cuts straight and controlled even in demanding demolition scenarios.
- 5-Piece Pack - having multiple blades on hand means you can rotate fresh blades into service without interruption, especially useful during extended rescue or jobsite demolition work.
Why This Product
- Rescue and demolition work involves mixed, unpredictable materials - the 5-8 TPI variable tooth design means a single blade type covers wood with embedded nails, metal, and glass fibre reinforced panels without constant blade changes.
- At 12 inches total length with an 11-inch cutting height and a maximum cutting capacity under 10 inches, these blades are purpose-built for deep cuts through thick structural assemblies that shorter general-purpose blades simply cannot reach.
- The BIM construction delivers the toughness needed for cutting chipboard, fiberglass, and wood-and-nail combinations - materials that rapidly destroy lesser carbon steel blades - extending usable blade life across a full demolition project.
- Coming in a 5-piece pack, this set gives crews a ready supply of identical blades so work never stalls because of a worn-out blade, making it a practical choice for jobsites where downtime is costly.

Frequently Asked Questions
What materials can these blades cut?
These blades are designed to cut wood with nails or metal, chipboard, and glass fibre reinforced materials, with a maximum material thickness of less than 10 inches. They are specifically intended for rescue and demolition applications where mixed materials are common.
What does the variable 5-8 TPI tooth pattern mean in practice?
The 5-8 TPI (teeth per inch) variable pattern means the tooth spacing progresses along the blade length, with fewer, larger teeth for aggressive cuts through wood and more closely spaced teeth for cleaner cuts through metal and composite materials. This allows one blade to handle a range of materials without swapping blades.
What is BIM and why does it matter for demolition work?
BIM stands for bi-metal, a construction method that bonds high-speed steel teeth to a flexible spring-steel back. For demolition and rescue work, this means the teeth resist wear from abrasive or hard materials like nails and metal, while the flexible back resists snapping under the twisting and angled forces common in rough cutting conditions.
What is the actual usable cutting length of these blades?
While the total blade length is 12 inches, the effective cutting height is 11 inches, which is the portion of the blade that actively engages the material. This allows the blade to handle cuts through material up to just under 10 inches thick as specified.
