What it is:

The 48-42-5161 is a Milwaukee 3" 24 TPI bi-metal T-shank jig saw blade set (5-pack) built for thin metal cutting with a clean finish.

Key specs:

• Blade length: 3 inches
• TPI (teeth per inch): 24
• Material: Bi-metal
• Shank: T-shank (modern quick-change)

Key features:

• Fine 24 TPI teeth: Produces smoother, cleaner cuts in thin metal
• Bi-metal construction: Longer life than carbon or HSS blades

In plain terms:

This is your fine-finish metal blade—the cleanest cutting option in the lineup you’ve been working through.

Best for:

• sheet metal
• thin steel
• light-gauge materials
• precise cuts where edge quality matters

Where it fits vs your other blades:

• 48-42-2160 (U-shank, 24 TPI): same purpose, older shank
• 48-42-5121 (18 TPI): medium metal (balanced)
• 48-42-2190 (14 TPI): thick metal (aggressive)
• 48-42-5161 (this): thin metal / cleanest cuts

Simple takeaway:

• 5161 = thin metal blade (T-shank)
• 24 TPI = fine, smooth cuts
• Bi-metal = durability + longer life
• Best when you care about cut quality over speed
