Irwin 14028 Marathon Carbide Circular Saw Blade, 7-1/4" 18T

Irwin 14028 Marathon Carbide Circular Saw Blade, 7-1/4" 18T

The Irwin 14028 Marathon Carbide Circular Saw Blade is a 7-1/4" corded circular saw blade with an 18-tooth (18T) count, engineered for fast, clean cuts in medium-thickness metals. Face-ground, construction-grade carbide teeth combine with an ultra-thin 0.017" kerf to reduce material removed per cut, deliver more cuts per charge on cordless tools, and extend battery run time. An aggressive 20° hook angle keeps the blade moving quickly through the workpiece, while Alternate Top Bevel (ATB) tooth grinding and a thicker plate design support accurate tracking and long tool life for both professional and DIY metal-cutting work.
