3" 20TPI T-Shank Wood Bi-Metal Jig Saw Blades 5PK

What it is:

The 48-42-5385 is a Milwaukee 4-inch 10 TPI bi-metal T-shank jig saw blade set (5-pack). It’s a general-purpose cutting blade designed for wood and light metal applications, similar in category to other 10 TPI “multi-material” blades in the 48-42 series.

Key specs:

• Blade length: 4 inches
• TPI: 10
• Material: Bi-metal (HSS teeth + flexible backing)
• Shank: T-shank (modern jig saw standard)
• Pack size: 5 blades
• Best for: Wood, nail-embedded wood, light metal

Key features:

• Bi-metal construction: Longer life than carbon steel blades
• 10 TPI tooth design: Fast cutting with decent finish balance
• Multi-material capability: Handles wood and light metal in one blade
• Durability-focused design: Built for jobsite and demolition-style use
• T-shank fit: Compatible with most modern jig saws

In plain terms:

This is a “general-purpose / demo-style” jig saw blade.

It’s not specialized like:

• 24 TPI (fine metal cutting)
• 14 TPI (thick metal cutting)
• or dedicated wood-only blades

Instead, it’s meant for mixed conditions, especially:

• wood with nails
• framing
• remodel / demolition work
• situations where speed matters more than a perfect finish

How it fits in your lineup:

• 5310: similar general-purpose wood/nail blade
• 2310: multi-material, slightly different geometry
• 5385 (this): general-purpose T-shank version in that same “do-it-all” category
