Irwin Marathon 14050 8-1/4" 24-Tooth Carbide Table & Miter Saw Blade

The Irwin Marathon 14050 is an 8-1/4" carbide-tipped circular saw blade engineered for miter and table saws where smooth finish and accurate cuts are critical. Built with 24 diamond-ground carbide teeth, a 5/8" arbor, and an ultra-thin 0.083" kerf, this blade is precision-tensioned and dynamically balanced for consistent, controlled cutting performance. The 400 grit diamond-ground carbide teeth combined with an aggressive 20° hook angle deliver fast, clean cuts, while the 24-tooth count makes this blade well suited for framing, ripping, and deck jobs. The thin-kerf design removes less material per pass, which means less resistance on the motor and, on cordless miter and table saws, more cuts per battery charge.

Key Features

  • Blade Diameter & Tooth Count: 8-1/4" diameter with 24 carbide teeth, ideally suited for framing, ripping, and deck jobs.
  • Diamond-Ground Carbide Teeth: 400 grit diamond-ground construction-grade carbide teeth for fast, clean cuts and long tool life.
  • Alternate Top Bevel (ATB) Tooth Configuration: ATB grind paired with an aggressive 20° hook angle for fast, efficient cutting.
  • Ultra-Thin Kerf: 0.083" kerf removes less material per cut, extending cordless tool battery life and reducing motor strain.
  • 5/8" Diamond Arbor: Precision 5/8" arbor sizing for a direct fit on compatible miter and table saws.
  • Maximum Speed Rating: Rated up to 7000 RPM for safe, reliable use on miter and table saws.
  • Precision-Tensioned & Balanced: Engineered tensioning and balance deliver a smooth finish and accurate, repeatable cuts.

Irwin 14050ZR – Frequently Asked Questions

1) Will the Irwin Marathon 14050 8-1/4 inch blade fit my cordless miter saw with a 5/8 inch arbor?
Yes. The Marathon 14050 is an 8-1/4 inch blade with a 5/8 inch diamond arbor, which is the standard arbor on 8-1/4 inch miter and table saws, so it mounts directly with no bushing or reducer. It has no 13/16 inch diamond arbor knockout, so it cannot be opened up to a larger spindle. Check that your saw's no-load speed does not exceed the blade's 7000 RPM maximum.
2) Is a 24-tooth blade the right choice for finish cuts, or should I use a higher tooth count?
24 teeth is a framing and ripping count. The Marathon 14050 pairs an alternate top bevel grind with an aggressive 20 degree hook angle, which is built to clear chips fast through framing lumber, rip cuts, and deck boards. For trim, moulding, plywood veneer, or anything where tear-out shows, step up to a higher tooth count blade in the same 8-1/4 inch, 5/8 inch arbor size. Running 24 teeth on finish work gets you speed, not a glass-smooth edge.
3) Does a thin kerf blade actually get more cuts out of a cordless saw battery?
That is the point of the 0.083 inch kerf on the Marathon 14050. Less material removed per pass means less resistance on the motor, which on a cordless miter or table saw translates into more cuts per charge and less bogging under load. The tradeoff with any thin kerf blade is that it is less rigid than a full kerf plate, so feed it steadily and let the blade do the work rather than pushing stock through.
4) What is the maximum RPM on the Irwin Marathon 14050 saw blade?
7000 RPM. That covers typical 8-1/4 inch miter saws and jobsite table saws, which generally run in the 4,000 to 6,000 RPM range unloaded. Do not mount it on any saw whose no-load speed is above 7000 RPM.
5) What are the teeth made of on the Marathon 14050, and will they hold up to pressure-treated deck lumber?
The teeth are construction-grade carbide, diamond ground to a 400 grit finish, and the plate is precision tensioned and dynamically balanced. Carbide is what lets the blade keep an edge through framing lumber and deck work rather than dulling the way high-speed steel does. It is a general-purpose wood cutting blade, not a metal or masonry blade.
6) Can I run the Marathon 14050 in a circular saw instead of a miter or table saw?
It is specified for miter and table saws, where the 20 degree hook angle and thin kerf are matched to the fixed-speed, guided cut. An aggressive hook angle on a hand-held circular saw tends to self-feed and grab. If you need an 8-1/4 inch blade for a sidewinder, pick one rated for circular saw use; for crosscutting on a miter saw and ripping on a table saw, this is the intended application.
