Product Description
Milwaukee Jig Saw Blade Bi-Metal 12 TPI 3 in. — 5 Pack
Model Number: 48-42-5390
The Milwaukee 48-42-5390 is a 5-pack of 3 in. Bi-Metal 12 TPI Jig Saw Blades — a shorter, finer-tooth blade specification for clean, accurate jig saw cuts in metal, thin materials, and applications where the shorter blade length provides better access and control in restricted cutting spaces. Milwaukee engineers bi-metal jig saw blades with precise material specification and manufacturing process for professional cutting performance — the bi-metal construction bonds HSS teeth to a flexible alloy steel body for the combination of cutting edge durability and blade body flexibility that extends blade life and maintains cutting performance beyond what single-material blade constructions provide in comparable applications. The 12 TPI fine tooth count is the right specification for thin metal cutting, light-gauge sheet metal, aluminum, and other materials where the higher tooth count keeps multiple teeth in simultaneous contact with the material throughout the cutting stroke, eliminating the tooth-catching and blade-deflection vibration that coarser tooth specifications produce in thin materials.
The 3 in. blade length is the short-blade specification for jig saw applications where limited clearance height above the work surface restricts the blade length that can be used without the blade contacting surrounding structure or material above the cut — flush cuts against wall surfaces, cuts in recessed or elevated locations, and cutting in enclosures and confined spaces where standard 4 in. or longer blades would extend beyond the available clearance. Short blades also reduce blade deflection during cutting compared to longer blades, improving straight-cut accuracy in applications where the blade must follow a precise cut line without lateral wandering. The 5-pack provides economical multi-blade supply for professional users who use the 3 in. 12 TPI specification regularly in metal cutting and precision cutting applications.
Milwaukee's complete jig saw blade lineup covers all standard lengths from 2-3/4 in. through 6 in. in a full range of TPI specifications and material constructions for every cutting application — see the full range for all available specifications.
