Irwin 14130 Marathon 7 1/4-Inch 24T Carbide-Tipped Decking Circular Saw Blade

The Irwin 14130 Marathon 7 1/4-Inch 24T Carbide-Tipped Decking Circular Saw Blade is engineered for fast, durable cuts in decking and general carpentry applications. Built with high-density tungsten carbide teeth in an Alternate Top Bevel (ATB) configuration, this 24-tooth blade features a 0.071 In thin kerf for efficient material removal and a 5/8 in arbor with a 13/16 Inch Diamond Arbor Knockout for broad saw compatibility. Heat/vent expansion slots reduce vibration for straighter cuts, while a reinforced shoulder and non-stick coating add long-term durability and smooth cutting performance across repeated use.

Key Features

  • Thin Kerf Design: 0.071 In thin kerf removes less material per pass for faster, more efficient cutting.
  • High-Density Tungsten Carbide Teeth: Alternate Top Bevel (ATB) tooth configuration is ground thin to stay sharp longer and cut faster through decking material.
  • Reinforced Shoulder: Added shoulder reinforcement improves overall blade durability under repeated use.
  • Heat/Vent Expansion Slots: Reduce vibration during operation, extending blade life and producing straighter cuts.
  • Arbor Compatibility: 5/8 in arbor size with a 13/16 Inch Diamond Arbor Knockout fits a wide range of circular saws.
  • Maximum Speed: Rated to 7000 RPM for consistent performance across compatible saws.
  • Hook Angle: 20-degree hook angle supports fast, efficient tooth engagement.
  • Non-Stick Coating: Reduces friction and material buildup on the blade body during use.

Irwin 14130 – Frequently Asked Questions

1) Will the Irwin 14130 Marathon blade fit my 7-1/4 inch circular saw with a 5/8 inch arbor?
Yes. The Irwin 14130 Marathon is a 7-1/4 inch blade with a 5/8 inch arbor, which is the standard spindle size on corded and cordless 7-1/4 inch circular saws. It also has a 13/16 inch diamond arbor knockout, so it can be converted for saws using a diamond arbor instead of a round one. Max speed is 7000 RPM, so confirm your saw's no-load speed does not exceed that.
2) Is a 24-tooth blade the right choice for cutting composite or pressure-treated deck boards?
A 24-tooth count is a framing and decking configuration: fewer, larger teeth clear chips fast and cut quickly through treated lumber and deck boards, with a rougher edge than a finish blade. The 14130 Marathon pairs that with an Alternate Top Bevel grind and a 20 degree hook angle for aggressive tooth engagement. If you need a clean, splinter-free edge on trim, plywood veneer or melamine, step up to a 40 tooth or higher blade instead.
3) What does the 0.071 inch thin kerf mean for cutting on a cordless saw?
A 0.071 inch kerf means the blade removes a narrower ribbon of material per pass than a standard full-kerf blade, so the saw works less and a battery saw gets more cuts per charge. The tradeoff with any thin kerf is that the plate is less rigid, so let the blade do the work rather than forcing it through. Heat and vent expansion slots in the 14130 help keep the plate running flat and cutting straight.
4) Can I use the Irwin 14130 for rip cuts and crosscuts, or do I need separate blades?
One blade covers both. The Alternate Top Bevel tooth grind on the 14130 Marathon handles rip and crosscut work in wood, framing, and general carpentry, which is why a single 24 tooth blade usually stays on a jobsite circular saw all day. Dedicated rip and crosscut blades only matter when you're chasing finish quality.
5) Are the teeth carbide or just hardened steel?
Carbide tipped. The 14130 uses high-density tungsten carbide teeth brazed to the plate, with a reinforced shoulder behind each tooth for durability under repeated use. That holds an edge far longer than a plain steel blade in treated decking, which is abrasive and dulls steel quickly.
6) What is the non-stick coating on the Irwin Marathon blade for?
The coating cuts friction and keeps pitch, resin and sawdust from building up on the blade body. That matters most in wet or resinous material like freshly treated deck boards, where gum on the plate causes binding and burning. Less drag also means the plate runs cooler.
7) What is the exact part number and maker of this decking blade for a purchase order?
It's the Irwin Marathon, manufacturer part number 14130, a 7-1/4 inch 24 tooth carbide-tipped circular saw blade. Country of origin is Vietnam.
8) Will the 20 degree hook angle cause the saw to grab in thin material?
A 20 degree hook is a positive, aggressive angle built for fast feed in solid wood and decking on a handheld circular saw. It pulls into the cut, which is what you want in framing lumber, but it is not the geometry for sheet aluminium or thin plastics, where a low or negative hook blade is the correct tool.
