Product Description
CMT JS922AF-5 Reciprocating Saw Blades for Metal - BIM 6" x 24TPI (5-Piece Pack) are precision-engineered bi-metal sabre saw blades designed for cutting thin sheet metal, fine pipe, and profiles with accuracy and control. Built from BIM (bi-metal) construction, these 6-inch reciprocating blades deliver clean, fine cuts through sheet metal ranging from 0.7mm to 3mm (1/32" to 1/8") in thickness, making them a go-to choice for HVAC work, metalworking, and detailed fabrication tasks. The 24 TPI tooth configuration ensures smooth, controlled cutting through thin metal profiles and fine pipe without tearing or distorting the material.
Key Features
- BIM (Bi-Metal) Construction - combines the flexibility of spring steel with the hardness of high-speed steel teeth, so the blade resists snapping under flex while staying sharp through demanding metal cutting tasks.
- 24 TPI Tooth Count - high tooth density produces fine, smooth cuts in thin sheet metal and profiles, reducing burrs and minimizing finishing work after cutting.
- 1mm Tooth Distance - tight, consistent tooth spacing is optimized for thin-wall metal cutting from 0.7mm to 3mm thick, preventing tooth stripping and blade skipping on light gauge material.
- 6-Inch Total Blade Length with 5-1/8" Cutting Height - the compact yet capable profile fits into confined work areas while delivering a usable cutting reach that handles pipes and profiles up to 4" maximum thickness.
- 0.035" Blade (Teeth) Thickness - a slim kerf profile reduces material resistance and makes maneuvering through thin metal cleaner and more precise.
- 5-Piece Pack - multiple blades included so you have replacements ready on the job, reducing downtime and keeping work moving.
Why This Product
- Engineered specifically for thin sheet metal from 0.7mm to 3mm (1/32" to 1/8") thick - this is not a general-purpose blade, but a task-matched tool for fine metal cutting where tooth count and kerf control matter most.
- The 24 TPI configuration paired with BIM construction means the blade handles fine pipe and profiles without the tooth stripping that commonly occurs when using lower-TPI blades on thin-wall material.
- At 6 inches in length with a 5-1/8" cutting height, these blades provide enough reach to work through pipes and metal profiles up to 4" in maximum thickness, covering a practical range of HVAC and fabrication applications.
- Sold as a 5-piece set, providing a ready supply of matched blades so work is not interrupted by a single worn blade - each replacement is identical in spec, ensuring consistent results throughout a project.

Frequently Asked Questions
What thickness of sheet metal can these blades cut?
These blades are designed for thin sheet metal from 0.7mm to 3mm in thickness, which corresponds to approximately 1/32" to 1/8". They are not intended for heavy plate or thick structural steel.
What does BIM mean and why does it matter for metal cutting?
BIM stands for bi-metal, a construction method that bonds high-speed steel teeth to a flexible steel back. For metal cutting, this means the teeth stay sharp longer than carbon steel blades while the body flexes rather than snapping under side load - important when working in tight or curved cuts through pipe and profiles.
What is the maximum pipe or profile size these blades can handle?
According to the product specifications, these blades are rated for a maximum material thickness of less than 4 inches, making them suitable for fine pipe and profiles within that range.
Why is 24 TPI the right tooth count for thin sheet metal?
A 24 TPI count ensures that multiple teeth are always in contact with thin material as the blade strokes, which prevents individual teeth from catching on the edge of light-gauge metal and causing tearing, stripping, or blade deflection. The 1mm tooth distance on these blades is specifically matched to the 0.7mm to 3mm target material range.
