The Milwaukee 49-00-5450 is a 4" reciprocating saw blade set (5-pack) designed for general-purpose metal cutting in tight spaces, especially with M12 HACKZALL™ or compact Sawzall® tools.

What it is

• Type: Reciprocating saw blade
• Length: 4"
• TPI: ~18–24 TPI (fine-to-medium metal cutting range)
• Material: Bi-metal construction
• Pack size: 5 blades

This is a versatile metal-cutting blade, sitting between light sheet-metal blades and heavier demolition metal blades.

Key Features

• Thin kerf design → reduces cutting resistance and improves speed (also extends battery life)

• Works well in compact Hackzall saws

What it’s best for

• Nails in wood (light demolition use)
• Electrical and plumbing rough-in work
• Tight-space cutting where full-size blades won’t fit
