When it comes to cutting through tough road surfaces, few tools perform as well as overlay blades<\/strong>, also known as AOC diamond blades<\/strong> (Asphalt Over Concrete). These blades are engineered for one of the most demanding jobs in construction. Cutting asphalt that has been laid directly over concrete. If you work in road construction, paving, or heavy-duty cutting projects, knowing when and how to use overlay blades can save time, reduce downtime, and increase job site efficiency.<\/p>\n\n\n\n

What Are Overlay Blades?<\/h2>\n\n\n\n

Overlay, or AOC blades are premium-grade diamond blades<\/strong> specifically designed for cutting asphalt layered over concrete<\/strong>. Unlike standard asphalt or concrete blades, these blades are built to handle the unique challenges of cutting through two very different materials in one pass.<\/p>\n\n\n\n

Asphalt is softer and more abrasive, while concrete is much harder. Standard blades wear down too quickly or fail to cut cleanly when faced with this combination. Overlay blades, however, feature advanced diamond segments and bonding technology<\/strong> that deliver both speed and durability.<\/p>\n\n\n\n

At Diamond King Tools, our overlay blades are trusted by some of the biggest road-cutting professionals in the country. Available in sizes ranging from 18″ to 36″<\/strong>, and with custom manufacturing options for even larger diameters, these blades are built for serious pros running saws from 11 horsepower up to 100 horsepower<\/strong>.<\/p>\n\n\n\n

Why Use Overlay Blades?<\/h2>\n\n\n\n

The key advantage of these blades is their versatility and performance<\/strong> when cutting composite surfaces. Here\u2019s why contractors rely on them:<\/p>\n\n\n\n

    \n
  1. Supreme Cutting Action<\/strong> – The segment design ensures smooth, efficient cutting through asphalt, concrete, or both.<\/li>\n\n\n\n
  2. Longer Blade Life<\/strong> – Premium bonding and diamond concentration extend the life of the blade, reducing replacement costs.<\/li>\n\n\n\n
  3. Faster Production<\/strong> – High cutting speed keeps projects on schedule, especially on road and highway jobs where time is critical.<\/li>\n\n\n\n
  4. Professional Reliability<\/strong> – These blades are engineered for contractors who can\u2019t afford downtime or blade failure.<\/li>\n<\/ol>\n\n\n\n
