4" 6TPI T-Shank Wood High Carbon Steel Jig Saw Blades 5PK

What it is:

The 48-42-5500 is a Milwaukee 4" 6 TPI high-carbon steel T-shank jig saw blade set (5-pack) designed for fast, rough wood cutting.

Key specs:

• Blade length: 4 inches
• TPI: 6 (very coarse teeth)
• Material: High carbon steel (HCS)
• Shank: T-shank (modern jig saw standard)
• Pack size: 5 blades
• Application: Wood (fast, rough cuts)

Key features:

• Very aggressive 6 TPI tooth pattern: Cuts wood extremely fast
• High carbon steel construction: Flexible, good for straight rough cuts
• Heavy-duty design: Built for jobsite use and longer life in demanding cutting
• Fast material removal: Prioritizes speed over clean finish
• T-shank compatibility: Fits most modern jig saws

In plain terms:

This is basically a “rough framing / demolition wood blade.”

It’s not for clean finish work. It’s meant for:

• fast ripping through lumber
• demolition cuts
• rough framing
• situations where speed matters more than accuracy

The 6 TPI is very coarse, so it:

• cuts fast
• leaves a rough edge
• can handle thicker wood easily

Simple takeaway:

• 48-42-5500 = fast wood-cutting jigsaw blade
• 6 TPI = very aggressive, rough cuts
• High carbon steel = flexible, general wood blade
• Best for framing, demo, and quick cuts—not finish work
