Product Description
Milwaukee Jig Saw Blade Bi-Metal 24 TPI 3 in. — 5 Pack
Model Number: 48-42-5161
The Milwaukee 48-42-5161 is a 5-pack of 3 in. Bi-Metal 24 TPI Jig Saw Blades — the finest-tooth bi-metal specification for ultra-clean, smooth-finish cuts in thin metal, non-ferrous sheet, and stainless steel where bi-metal construction's extended life advantage over HSS blades justifies the cost premium in high-volume cutting applications. At 24 TPI, the maximum tooth density keeps the highest possible number of teeth simultaneously engaged with thin metal material during the cutting stroke, producing the smoothest possible cut surface, the least burr formation, and the finest cut edge finish quality available in bi-metal jig saw blade specifications. Bi-metal construction bonds HSS cutting teeth to a flexible alloy steel blade body — the HSS teeth provide the hardness for metal cutting edge retention in thin metal work, while the alloy steel body resists the fatigue cracking that makes all-HSS blades brittle in the bending loads of jig saw operation, extending blade life substantially compared to HSS-only blades in the same application.
The 3 in. short blade length is the correct specification for confined-access cutting in metal enclosures, for flush cuts against adjacent structure, and for cutting applications where the clearance above the work surface limits the usable blade length — short blades also reduce lateral blade deflection during cutting compared to longer blades, improving straight-cut accuracy in precision metal work. The combination of 24 TPI ultra-fine tooth, bi-metal durability, and 3 in. short blade makes this the professional specification for thin-material metal work requiring the best available cut surface quality and long blade life in applications where bi-metal economics are appropriate. The 5-pack provides a practical blade supply for sheet metal and precision metal cutting projects.
For lower-volume thin metal cutting where HSS cost economy is preferred over bi-metal life extension, Milwaukee's 24 TPI HSS jig saw blades (48-42-0140) provide the same tooth specification at lower per-blade cost — see the full Milwaukee jig saw lineup for all options.
