5-1/4" 14TPI T-Shank Metal Cutting Bi-Metal Jig Saw Blades 5PK

What it is:
Milwaukee 3" 14 TPI bi-metal T-shank jig saw blade (5-pack) designed for heavy metal cutting.

Key specs

• Length: 3"
• TPI: 14 (coarse metal-cutting tooth pattern)
• Material: Bi-metal (flexible body + hardened teeth)
• Shank: T-shank (modern quick-change jig saw fit)
• Pack size: 5 blades
• Best use: Thick metal (~1/4" and up)

What makes it different

• 14 TPI = aggressive cut
  • Fewer teeth biting at once
  • Faster cutting in thick steel
  • Rougher edge than higher-TPI blades
• Bi-metal construction
  • Handles heat and stress better than basic steel blades
  • Less likely to snap in heavy material

Where it sits in your blade lineup

• 5161 (24 TPI): thin metal / clean finish
• 5121 (18 TPI): general metal / balanced cut
• 5190 (14 TPI): thick metal / fastest, most aggressive cutting

So yes—this is the “heavy hitter” metal blade in that group.
