Irwin 14015 Marathon 7 1/4-Inch 24-Tooth Thin-Kerf Carbide-Tipped Circular Saw Blade

The Irwin 14015 Marathon 7 1/4-Inch 24-Tooth Circular Saw Blade delivers fast, straight cuts for general-purpose wood cutting in framing, remodeling, and workshop projects. Built with high-density tungsten carbide teeth ground in an Alternate Top Bevel (ATB) configuration, this thin-kerf blade measures just 0.063 In thick and pairs a reinforced shoulder with heat/vent expansion slots to reduce vibration and extend blade life. Irwin's Marathon 7 1/4-Inch platform is also offered in additional Model options (14017, 14029, 14030, 14031, 24021) for different tooth counts and cutting tasks, with this listing covering the 14015 24-Tooth configuration. The exclusive every-other-tooth design keeps alternating carbide teeth ground thinner so they stay sharper longer for faster, cleaner cuts on the job site or in the shop.

Key Features

  • Trade Size: 7 1/4-Inch diameter blade sized to fit standard corded and cordless circular saws.
  • Tooth Count: 24 teeth ground in an Alternate Top Bevel (ATB) configuration for fast, general-purpose ripping and crosscutting.
  • Durable Construction: High-density tungsten carbide tips deliver toughness and long life, even through repeated cuts in dense lumber.
  • Thin-Kerf Design: 0.063 In plate thickness removes less material per pass, enabling faster cuts with less strain on the saw motor while supporting stable, straight tracking.
  • Reinforced Shoulder: Adds durability and helps the blade body resist stress on demanding jobsite cuts.

Irwin IRW-14015 – Frequently Asked Questions

1) Will the Irwin Marathon 14015 blade fit my cordless 7-1/4 inch circular saw?
The Marathon 14015 is a 7-1/4 inch diameter blade sized for standard corded and cordless circular saws. The thin 0.063 inch plate means it removes less material per pass, which is what you want on a battery saw since it puts less load on the motor and stretches runtime per charge.
2) Is a 24-tooth carbide blade the right choice for framing, or should I go with a higher tooth count?
24 teeth is the framing and rough carpentry count. Fewer, larger teeth clear chips fast so you rip and crosscut dimensional lumber quickly without bogging the saw. If you need a cleaner edge for finish work, plywood, or trim, step up in tooth count - Irwin's Marathon 7-1/4 inch platform is also offered in models 14017, 14029, 14030, 14031 and 24021 for different tooth counts and cutting tasks.
3) What does the ATB tooth grind on this Irwin Marathon blade actually do on the cut?
Alternate Top Bevel means the carbide teeth are beveled in alternating directions, so each tooth slices the wood fibers rather than chiseling them. That gives you a cleaner edge on crosscuts than a flat-top grind at the same tooth count, while still cutting fast enough for general-purpose wood work.
4) Does the Irwin 14015 come as a single blade or a multi-pack?
It is sold as an individual blade, not a set. Packaging is 10 each, so a full case carries ten single blades - useful if you are stocking a crew or a shop and going through blades on framing work.
5) Which Irwin Marathon model numbers should I order if I want more than the 24-tooth blade?
The 24-tooth Marathon is model 14015. Orderable Marathon 7-1/4 inch models alongside it are 14017, 14029 and 24021, each a different tooth count for a different cutting task. Order by model number so you get the tooth count you actually want - the diameter is the same across them.
6) Is a thin-kerf blade going to wander or cut crooked in 2x material?
The 14015's 0.063 inch plate is thin kerf, and Irwin backs it with a reinforced shoulder plus heat and vent expansion slots to cut vibration and keep the body stable. In practice the thin kerf takes less bite per pass, so it tracks straight on 2x lumber while pulling less amperage than a full-kerf blade.
7) Will this Irwin blade hold up cutting dense or engineered lumber?
The teeth are high-density tungsten carbide, which is what handles repeated cuts in dense lumber without rounding over fast. It is a wood-cutting blade though - for masonry, metal or abrasive board you want a blade specified for that material, not a carbide-tipped wood blade.
8) Does the Irwin 14015 Marathon blade carry a Prop 65 warning?
No Prop 65 warning applies to the 14015 Marathon blade. It is manufactured in Vietnam. That matters if you are buying for a California facility or need the documentation clean for an institutional purchase order.
