Lenox 21511B118R Reciprocating Saw Blade 18 Tpi 25 Pack

Product Description

The LENOX 21511B118R is a 12-inch bi-metal reciprocating saw blade engineered for cutting metal. Built with an 18-teeth-per-inch (TPI) toothed edge and a straight profile, it delivers controlled, clean cuts in ferrous and non-ferrous metals. The bi-metal construction bonds a high-speed steel tooth edge to a flexible alloy steel body, giving the blade resistance to tooth breakage while maintaining flexibility under load. At 0.035 inches thick, the blade stays rigid enough for accurate cuts without binding in the kerf. This blade is used by electricians, plumbers, pipefitters, HVAC technicians, and general contractors who need a reliable metal-cutting blade for a standard reciprocating saw.

This blade is suited for residential and commercial service work where cutting pipe, conduit, metal framing, strut, sheet metal, and similar materials is required. The 12-inch length provides reach in confined spaces and allows for deeper cuts compared to shorter-length blades. Sold in a 25-pack, making it practical for job-site stocking or fleet tool kits. Typical applications include pipe removal, conduit cuts, and metal demolition work where a coarse 18 TPI configuration is appropriate for faster stock removal in thicker metal sections.

Compatibility

Designed as a standard-shank reciprocating saw blade compatible with reciprocating saws that accept universal T-shank or straight-shank blade mounting systems. Verify shank type against your tool before installation.

Installation Notes

Reciprocating saw blade changes should be performed with the tool unpowered and the battery removed or the cord unplugged. Use appropriate blade-clamp tooling per the saw manufacturer instructions to seat the blade securely before cutting. Eye protection and cut-resistant gloves are standard PPE when operating reciprocating saws. Ensure the workpiece is secured before starting a cut to prevent blade binding or kickback.
