Product Description
CMT JS1122BF-20 Reciprocating Saw Blades for Metal - BIM 9" x 14 TPI (20-Pack) are professional-grade bi-metal sabre saw blades engineered for cutting thick sheet metal, solid pipe, and structural profiles. Spanning a full 9 inches in total length with an 8-inch cutting height, these blades are purpose-built to handle material thicknesses from 1/8 inch up to 5/16 inch with consistent, controlled results. The 20-piece bulk pack delivers exceptional value for contractors and tradespeople who rely on high-cycle blade performance in metalworking applications.
Key Features
- Bi-Metal (BIM) Construction - the combination of high-speed steel teeth bonded to a flexible spring-steel back gives these blades both hardness and flex, reducing breakage during demanding cuts through pipe and solid metal profiles.
- 14 TPI Tooth Configuration with 1.8mm Tooth Distance - the tooth spacing is optimized for thick sheet metal from 3mm to 8mm (1/8 inch to 5/16 inch), delivering smooth, efficient material removal without tooth stripping.
- 9-Inch Total Length with 8-Inch Cutting Height - the extended reach allows operators to work on larger-diameter pipe and deeper structural profiles, reducing repositioning and improving cut-through efficiency.
- 0.035-Inch Blade Thickness - a precision-ground blade body maintains dimensional consistency throughout the cut stroke, supporting accurate tracking in metal cutting applications.
- 20-Piece Pack - stocking a full set of 20 blades keeps a jobsite supplied through high-volume cutting tasks, minimizing downtime from blade changes on thick metal stock.
- Designed for Thick Sheet Metal, Solid Pipe, and Profiles - the geometry and material composition are specifically matched to these applications, meaning the blade performs as intended rather than being adapted from a general-purpose design.
Why This Product
- Built for thick metal, not adapted for it - with a rated cutting range of 1/8 inch to 5/16 inch material thickness and a tooth pitch matched to that range, these blades are purpose-engineered for thick sheet metal, pipe, and profile work rather than repurposed from a thinner-gauge design.
- Bulk 20-piece quantity reduces mid-job blade shortages - having 20 blades on hand in a single pack means contractors can maintain cutting momentum through large-scale metal fabrication or demolition tasks without waiting on restocking.
- BIM material balances cutting aggression with blade longevity - the bi-metal construction handles the hardness of solid metal profiles and thick-walled pipe while resisting the flex fatigue that breaks single-material blades during long cut strokes.
- 9-inch blade length supports access in deeper or tighter cutting situations - the combination of total length and 8-inch cutting height gives operators more working reach when cutting through thick solid pipe or wide structural profiles in confined spaces.

Frequently Asked Questions
What material thickness range can these blades cut?
These blades are rated for cutting thick sheet metal, solid pipe, and profiles from 1/8 inch to 5/16 inch (3mm to 8mm) in thickness. The 14 TPI tooth pitch is specifically matched to this material thickness range for efficient cutting.
What does BIM mean and why does it matter for metal cutting?
BIM stands for Bi-Metal, which describes a blade construction that bonds high-speed steel cutting teeth to a flexible spring-steel back. This combination delivers the hardness needed to cut solid metal and thick pipe while maintaining the flexibility required to resist breakage during long, demanding cut strokes.
How long is the actual cutting reach of these blades?
The total blade length is 9 inches, and the usable cutting height is 8 inches. This provides sufficient reach for cutting through larger-diameter solid pipe and wide structural metal profiles in a single stroke.
Why does the 20-piece pack make sense for metal cutting work?
Cutting thick sheet metal, solid pipe, and structural profiles places significant demand on reciprocating saw blades. Having 20 blades in a single pack ensures that contractors and tradespeople can sustain high-volume cutting tasks without interruption from blade supply shortages on the jobsite.
