About Product Overview

An 80-tooth count on a 10" blade means fine, controlled cuts, and that's the point of the IRWIN Marathon steel/metal blade: it's built for cutting metal, not framing lumber. The MATB grind (modified alternate top bevel) is a common choice for cutting harder materials cleanly, reducing chipping and leaving a smoother edge than a low-tooth-count wood blade could manage.

With a .079" kerf, the blade removes a thin amount of material per pass, which helps conserve stock and keeps the cut precise. The 5/8" arbor is a standard fit for most 10" circular saws, and IRWIN caps the maximum speed at 1800 RPM, so check your saw's rated speed before mounting it. This is a single blade, carded for retail, and part of IRWIN's Marathon sub-brand, built for tradespeople who need a dependable metal-cutting blade without switching to a specialty tool.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
