CMT JS1122VF-5 Reciprocating Saw Blades for Wood and Metal are 9-inch bi-metal (BIM) saw blades engineered for demanding cutting tasks that span multiple material types - from lumber loaded with embedded nails to sheet metal, aluminum profiles, and fiberglass. Sold in a 5-piece pack, these blades feature a variable 10-14 TPI tooth pattern that adapts cutting aggressiveness to the material at hand, delivering fast stock removal alongside controlled finish quality. Whether you are demoing framing, trimming pipe, or cutting through composite assemblies on a job site, the CMT JS1122VF-5 gives you a versatile, long-lasting blade in a multi-pack format that keeps your saw running without interruption.

Key Features

• Bi-Metal (BIM) construction - the high-speed steel teeth bonded to a flexible spring-steel body resist breakage and wear far longer than single-material blades, reducing the frequency of blade changes during extended cuts through mixed materials.
• Variable 10-14 TPI tooth pattern - the progressive tooth spacing handles coarser wood demolition cuts and finer metal cuts within the same blade, so you spend less time swapping blades when working across different materials on the same project.
• 9-inch total length with 8-inch cutting depth - the generous usable cutting length reaches deep into framing members, aluminum sections, and thick sheet goods, giving you full control even in situations where clearance is limited.
• Maximum cutting capacity under 7 inches - handles wood with embedded nails, sheet metal, aluminum profiles, and fiberglass up to the rated capacity, making this a single blade solution for multi-material demolition and fabrication work.
• 0.035-inch blade thickness - a slim profile reduces binding and drag through cuts, helping maintain a straighter kerf and reducing operator fatigue during prolonged use.
• 1.8-2.6mm tooth distance (variable pitch) - the variable pitch minimizes vibration during cutting, which means smoother operation in the hand and less stress transferred to the reciprocating saw body.
• 5-piece pack format - stocking five blades at once ensures you always have a fresh blade ready, eliminating downtime on multi-day jobs or high-volume cutting work.

Why This Product

• If your work regularly takes you through wood framing with embedded nails followed immediately by sheet metal or aluminum profiles, this single blade handles both without requiring a tool change - the BIM construction and variable TPI address the competing demands of each material type.
• The 8-inch cutting depth and under-7-inch maximum thickness rating make this blade genuinely useful for thick demolition cuts through doubled framing members, deep aluminum extrusions, or layered fiberglass panels that shallower blades cannot reach.
• Variable pitch from 10 to 14 TPI actively reduces vibration during the cut compared to fixed-pitch blades, translating to more controlled tool handling and cleaner results on aluminum profiles and sheet metal where chatter causes poor edge quality.
• Buying in a 5-piece pack provides immediate on-hand inventory for high-cycle or multi-material jobs, making it practical for contractors and tradespeople who cannot afford to stop work when a blade reaches the end of its service life.
