Product Description
CMT JS1111DF-20 Reciprocating Saw Blades for Wood and Metal - BIM 9" x 6 TPI (20-Piece Pack) are heavy-duty bi-metal sabre saw blades engineered for demanding demolition and construction tasks. Designed to cut through wood with embedded nails, chipboard, plastic profiles, and glass, these 9-inch blades handle material up to 7 inches in thickness with a coarse 6 TPI tooth configuration that removes material quickly and efficiently. The 20-piece pack delivers exceptional value for contractors and trade professionals who rely on consistent blade performance across high-volume cutting applications.
Key Features
- Bi-Metal (BIM) Construction - high-speed steel teeth bonded to a flexible spring-steel body delivers both superior wear resistance and the flex needed to resist breakage during aggressive cuts through mixed materials like wood with nails or metal profiles.
- 9" Total Blade Length with 8" Cutting Height - the extended reach allows users to cut deeper into thick workpieces, handling materials up to 7 inches thick without repositioning the saw.
- 6 TPI Coarse Tooth Spacing - the wide 4.3mm tooth pitch evacuates chips rapidly and reduces heat buildup, making it ideal for fast, straight cuts through thick wood, chipboard, and plastic profiles.
- Milled Tooth Geometry with Side Set - precision-milled and side-set teeth cut aggressively while maintaining a consistent kerf, reducing binding and keeping cuts on track even through irregular or embedded-nail-laden material.
- 0.049" Blade Thickness - this thickness balances rigidity for straight cuts with enough durability to withstand the stress of reciprocating saw vibration over extended use.
- 19mm Cutting Depth - the blade geometry is optimized to engage material efficiently at each stroke, contributing to faster stock removal per pass.
- 20-Piece Pack - stocking up with a full 20-blade set reduces downtime on the job by ensuring replacement blades are always on hand when a blade dulls or breaks mid-project.
Why This Product
- Versatile multi-material cutting in one blade - rather than switching between dedicated wood and metal blades, the BIM construction and 6 TPI coarse tooth pattern handle wood with embedded nails, chipboard, plastic profiles, and glass in a single blade, saving time and reducing the number of blade types to carry on site.
- Built for thick material up to 7 inches - the 9-inch blade length and 8-inch cutting height are specifically suited for demolition scenarios where walls, framing, or composite panels exceed what shorter blades can safely reach, giving users the clearance needed for complete through-cuts.
- Professional-grade quantity for high-volume work - the 20-piece pack is structured for contractors and crew leaders who need a reliable supply of fresh blades without repeated small-quantity purchases interrupting workflow.
- Precision milled teeth for consistent cutting performance - the SS (side-set) milled tooth profile maintains cutting accuracy on each blade from the first cut to the last, reducing the variability that can come from lower-tolerance blade manufacturing.

Frequently Asked Questions
What materials can these reciprocating saw blades cut?
These BIM blades are designed for cutting wood with embedded nails or metal, chipboard, plastic profiles, and glass. They are optimized for multi-material demolition and construction applications where a single blade needs to handle more than one substrate type in the same cut.
What is the maximum material thickness these blades can handle?
These blades are rated for cutting material less than 7 inches thick. With a total length of 9 inches and a cutting height of 8 inches, they provide enough reach for deep cuts through thick framing, panels, and composite materials within that limit.
What does BIM mean and why does it matter for durability?
BIM stands for Bi-Metal, which refers to a construction method that combines high-speed steel teeth with a flexible spring-steel blade body. The HSS teeth provide hardness and wear resistance for cutting through tough materials, while the spring-steel back resists bending and breakage during the back-and-forth motion of a reciprocating saw - extending the usable life of each blade compared to single-material alternatives.
What tooth configuration do these blades use and why is 6 TPI appropriate for this application?
These blades feature 6 TPI (teeth per inch) with a 4.3mm tooth distance and a milled, side-set tooth profile. A coarse 6 TPI configuration is well suited for fast material removal through thick wood, chipboard, and plastic profiles, as the wider spacing between teeth allows chips and debris to clear from the cut efficiently, reducing heat and maintaining cutting speed.
