4" 10TPI T-Shank Wood Bi-Metal Jig Saw Blades 5PK

What it is:

The 48-42-5311 is a Milwaukee 4" 10 TPI bi-metal T-shank jig saw blade set (5-pack) designed for fast wood cutting.

Key specs:

• Blade length: 4 inches
• Teeth per inch (TPI): 10
• Material: Bi-metal (HSS cutting edge + flexible body)
• Shank type: T-shank (modern quick-change style)
• Quantity: 5 blades
• Application: Wood cutting

Key features:

• Bi-metal construction: Longer life than carbon or basic steel blades
• 10 TPI tooth design: Fast, clean cuts in wood
• Heavy-duty build: Designed for professional use and durability
• T-shank design: Quick install, fits most modern jig saws

In plain terms:

This is basically the modern version of the wood blade you saw earlier (48-42-0640)—but with a T-shank instead of U-shank.

• 10 TPI = fast, general-purpose wood cutting
• Bi-metal = tougher, longer-lasting (can handle occasional nails better)
• T-shank = what most newer jig saws use today

Best for:

• lumber
• plywood
• trim
• general carpentry

Where it fits vs your other blades:

• 0640: wood blade (U-shank, older style)
• 5311 (this): wood blade (T-shank, modern standard)
• 2310: multi-material (wood + nails + light metal)
• 2160 / 2190: metal-specific blades
