Take your woodworking to the next level with the Irwin Marathon 12 in. Carbide Circular Saw Blade, engineered for precision, durability, and clean finishes across a range of materials. The carbide-tipped blade with 100 teeth delivers smooth crosscuts and refined edge quality for cabinetry, shelving, trim, and hobby projects.
Why this blade stands out
-
100 high-density carbide teeth paired with an ATB grind provide exceptionally smooth crosscuts and reduced tear-out on hardwoods, plywood, and engineered woods.
-
Thin kerf at .098" minimizes material waste and reduces strain on your saw, enabling faster, cleaner cuts.
-
12" diameter with a 1" arbor fits most standard 12" table saws and miter saws, offering broad compatibility for shop setups.
-
ATB grind with 10° hook angle balances aggressive cutting with precise finishes for long-term cut quality.
-
High RPM tolerance up to 8300 RPM means this blade maintains stability and accuracy on fast-powered saws.
-
Multi-purpose design optimized for a variety of woodworking tasks, from framing to fine finish work, helping you consolidate tools in your workshop.
-
Carded packaging includes a single blade, ready to install and go to work.
Ideal use cases
Use this blade for precise crosscuts in solid wood, plywood panels, and engineered lumber. It shines when making cabinet faces, door frames, shelving cuts, and trim where a clean, flush-cut edge matters. Its fine tooth count reduces chipping on veneered surfaces and panel goods when trimming panels or installing backer boards.
Practical tips for best results
- Ensure your saw is operated within the blade’s RPM range (up to 8300 RPM) for optimal performance and edge quality.
- Maintain a steady feed rate and let the blade do the work to minimize burn marks and chipping on delicate materials.
- Use a push stick and a stable work surface to maximize safety and cut accuracy.
- Replace blades with dull or chipped teeth to preserve finish quality on subsequent cuts.
