Product Description
Milwaukee Jig Saw Bi-Metal 18 TPI 3 in. — 5 Pack
Model Number: 48-42-5121
The Milwaukee 48-42-5121 is a 5-pack of 3 in. Bi-Metal 18 TPI Jig Saw Blades — ultra-fine-tooth bi-metal blades for precision thin metal cutting in the standard compact 3 in. length. The 18 TPI ultra-fine tooth count maximizes the number of teeth simultaneously engaged with thin metal material during each cutting stroke, producing the smoothest possible cut surface and minimum burr formation of any standard bi-metal jig saw blade specification in sheet metal applications. Bi-metal construction bonds HSS teeth to a flexible alloy steel body — the HSS teeth provide sharp, hard cutting edges for metal while the alloy body resists fatigue and fracture from the bending loads of jig saw operation. The 3 in. compact length is the standard jig saw blade format for most metal cutting applications, fitting the access requirements and cutting depth range of typical sheet metal, HVAC, and electrical enclosure work.
The combination of 18 TPI fine tooth and bi-metal durability makes this blade the professional specification for production thin-metal jig saw cutting where both cut quality and blade life under sustained use are important. Sheet metal workers, HVAC technicians, and electricians who regularly cut metal enclosures, ductwork sheet metal, and hardware materials use this specification for its smooth cut quality and bi-metal durability over the HCS option at the same TPI. The 5-pack provides a practical multi-blade supply for contractors who use this specification at production pace across commercial sheet metal and electrical work projects. Milwaukee manufactures these blades to consistent professional quality standards for predictable cutting performance throughout the 5-blade supply.
