Rip through thick lumber, framing, and demolition cuts with this Irwin Marathon carbon steel jigsaw blade. The aggressive 6 TPI tooth count clears chips quickly for fast material removal - ideal for rough cutting, opening up subfloor, or making fast curve cuts in 2x dimensional lumber where speed matters more than finish.

• High-carbon steel with fleam-ground teeth
• Fleam grind slices for a cleaner cut face
• 6 teeth per inch - aggressive, fast cutting
• 4" blade length
• U-shank fits jigsaws that take U-shank (universal) blades
• 2 blades per pack

Tip: Low TPI blades cut faster but rougher - use 6 TPI for rough framing and demo work where the cut face will be hidden, then switch to 10 TPI for finish-visible cuts.
