Product Description
Milwaukee Jig Saw Bi-Metal 18 TPI 2-3/4 in. — 5 Pack
Model Number: 48-42-2120
The Milwaukee 48-42-2120 is a 5-pack of 2-3/4 in. Bi-Metal 18 TPI Jig Saw Blades — the finest-tooth bi-metal jig saw blade in the compact 2-3/4 in. standard short format for precision thin-metal cutting in the tightest-clearance working positions. The 18 TPI ultra-fine tooth count maximizes teeth-in-contact 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 the sharp, hard cutting edges for metal, while the alloy body resists the fatigue and fracture from the bending loads of jig saw operation. The 2-3/4 in. compact length is the shortest standard jig saw blade format, fitting the most confined working clearances where standard 3 in. and 4 in. blades contact surrounding materials.
The combination of 18 TPI ultra-fine tooth and 2-3/4 in. compact length makes this a specialty bi-metal specification for precision thin-metal cutting in tight panel and enclosure spaces — cutting thin sheet metal inside electrical enclosures and equipment panels, trimming HVAC duct metal in confined mechanical room positions, and making precision metal detail cuts in the tight-clearance situations where no other blade combination provides the same quality access. The bi-metal construction adds the durability advantage over HSS in the same specification, providing better service life in sheet metal applications where the thinner material dimensions still present cutting edge wear over the blade's service life. The 5-pack provides multi-blade supply for precision metal panel work.
