The Milwaukee Electric Tool Corp 48-01-2184 is a 6-inch, 18-tooth bi-metal reciprocating saw blade engineered for cutting heavy gauge metal, conduit, tubing, channels, and pipe. The bi-metal construction combines a high-speed steel cutting edge with a flexible alloy steel body, delivering durability and resistance to blade fatigue under repeated use. Sold in bulk packs of 25, these blades are a practical stock-up option for electricians, plumbers, and mechanical contractors who run reciprocating saws on metal-cutting tasks daily. At 18 teeth per inch, the blade produces smooth, controlled cuts in thin-wall and medium-wall metal sections without aggressive tooth stripping.
This blade is suited for residential and commercial trade applications where metal cutting is frequent. Typical use cases include cutting EMT and rigid conduit during electrical rough-in, trimming threaded pipe and copper tubing in plumbing and mechanical work, and cutting unistrut channels and structural metal framing. The 6-inch length provides adequate depth of cut for most in-wall and overhead installations. The bulk packaging makes these blades appropriate for field service fleets, shop stock, and job-site replenishment.
Designed as an OEM-style replacement blade for use with standard universal-shank reciprocating saws used in electrical, plumbing, and mechanical trade applications.
Blade installation and changes should be performed with the saw powered off and the battery or power cord disconnected. Secure the workpiece before cutting to prevent movement and blade binding. Eye protection and cut-resistant gloves are recommended when handling and installing reciprocating saw blades. Confirm the blade shank is fully seated and locked in the tool chuck before beginning a cut.
