Product Description
CMT JS922EF-5 Reciprocating Saw Blades for Metal - BIM 6" x 18 TPI (5-Piece Pack) are precision-engineered bi-metal sabre saw blades designed specifically for cutting thin sheet metal, pipe, and profiles with accuracy and durability. Built from bi-metal (BIM) construction with a 1.4mm tooth distance and 18 teeth per inch, these 6-inch blades deliver clean, controlled cuts through thin metal stock ranging from 1.5mm to 4mm (1/16" to 5/32") in thickness - making them a reliable choice for metalworking professionals and tradespeople working with light gauge material, conduit, and structural profiles.
Key Features
- Bi-Metal (BIM) Construction - combines the flexibility of spring steel with the hardness of high-speed steel teeth, giving the blade long cutting life and resistance to breakage under demanding reciprocating saw use.
- 18 TPI Fine-Tooth Configuration - 18 teeth per inch with a 1.4mm tooth distance produces fine, precise cuts through thin sheet metal and profiles without tearing or distorting the workpiece.
- Optimized for Thin Metal (1.5mm to 4mm) - engineered specifically for material in the 1/16" to 5/32" thickness range, so the blade engages the stock correctly and avoids tooth stripping on light-gauge material.
- 6-Inch Total Length with 5-1/8" Cutting Height - the generous cutting height gives clearance for pipes, tubing, and profiles while keeping the blade compact enough for controlled work in tighter positions.
- 0.035" Blade Thickness - a slim kerf reduces cutting resistance and material waste, letting the blade move efficiently through metal without bogging down.
- 5-Piece Pack - multiple blades included so production jobs, high-volume cutting, or multi-user shops have backup blades on hand without needing to reorder mid-job.
Why This Product
- When cutting thin sheet metal in the 1/16" to 5/32" range, tooth count and pitch are critical - the 18 TPI layout on these BIM blades keeps enough teeth in contact with thin stock to prevent snagging, chattering, or tooth damage.
- The bi-metal material pairing means the cutting edge resists dulling during extended runs through pipe and profiles while the flexible back absorbs vibration and stress - reducing blade fatigue and snapping during use.
- The 1.4mm tooth distance is purpose-matched to thin-wall metal cutting applications, making these blades a more targeted choice than general-purpose reciprocating saw blades for the same job.
- Purchasing in a 5-piece set provides immediate backup when a blade dulls on a long run of cuts - keeping work moving without waiting for a single replacement blade to arrive.

Frequently Asked Questions
What thickness of sheet metal can these blades cut?
These blades are designed for cutting thin sheet metal from 1.5mm to 4mm in thickness, which corresponds to approximately 1/16" to 5/32". Using them within this range helps ensure proper tooth engagement and longer blade life.
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 applications, this means the teeth stay sharp longer under friction while the body of the blade resists snapping - particularly useful when cutting pipe and profiles that place lateral stress on the blade.
Why is 18 TPI the right tooth count for thin sheet metal?
A higher tooth-per-inch count like 18 TPI keeps more teeth in contact with the material at once when cutting thin stock. This prevents individual teeth from catching and stripping on light-gauge metal and produces a finer, cleaner cut edge compared to lower TPI blades suited for thicker materials.
Can these blades cut pipe and profiles as well as flat sheet metal?
Yes. In addition to flat sheet metal in the 1/16" to 5/32" thickness range, the JS922EF blades are specified for cutting pipe and profiles, making them versatile for HVAC work, plumbing rough-in, and light structural metal fabrication tasks.
