• Insert blade into a reciprocating saw that accepts universal or 1/2" shanks.
• Ensure the blade is installed in correct orientation (teeth forward).
• Start the saw and allow full speed before contacting material.
• Use firm, steady pressure when cutting to avoid blade breakage.
• Remove blade when it becomes dull or damaged and replace.

Q: Why use a 6 TPI blade for demolition work?
A: Lower TPI (6) yields faster, aggressive cuts, ideal for cutting through wood and nails. (See comparison of TPI for demolition blades.)

Q: What benefits do cobalt bi-metal blades provide?
A: Cobalt increases edge hardness and durability, helping the blade resist heat and wear in demanding cuts.

Q: What does “electron welded edge” mean for blade durability?
A: The cutting edge is fused to the back by high-energy welding, improving bond strength and reducing delamination risk.

Q: Will this blade fit standard reciprocating saws?
A: Yes, these blades work with universal shank and most 1/2" reciprocating saws. (Most bi-metal demo blades use standard shanks.)

Q: How can I extend blade life in tough conditions?
A: Use steady feed, avoid binding, clear material debris, and avoid overheating the blade.
