Dewalt DT20467-QZ Elite 350mm x 25.4mm Segmented Asphalt Diamond Blade

The Dewalt DT20467-QZ Elite 350mm x 25.4mm Segmented Asphalt Diamond Blade is a high performance, heavy duty cutting solution designed for professional groundworkers, builders, civil engineers and construction contractors.

Combining advanced diamond cutting technology with laser welded segments, a tungsten carbide reinforced matrix and a high alloy steel core, this professional diamond cutting disc delivers exceptional durability, fast cutting performance and reliable results when working with highly abrasive materials.

Featuring a large 350mm diameter and 25.4mm bore, the DT20467-QZ is specifically engineered for cutting asphalt and green concrete. These abrasive materials can cause rapid wear on conventional diamond blades, making the Elite Series an excellent choice for demanding roadworks, groundwork and construction applications where blade longevity and consistent cutting performance are essential.

Designed to deliver up to five times longer life compared with DEWALT HP diamond blades cutting C35 concrete, the Elite Series incorporates laser welded segments containing 20% more diamonds. This advanced construction creates a stronger cutting edge, helping reduce blade wear and minimise the frequency of replacements during intensive cutting applications.

The innovative tungsten carbide reinforced matrix further increases diamond bond strength, providing excellent resistance to the abrasive conditions encountered when cutting asphalt and freshly laid concrete. Combined with the durable laser welded drop segments, this reinforced construction helps maintain cutting performance and extend the working life of the blade.

A high alloy steel core provides excellent structural stability, supporting accurate straight cuts and deeper cutting applications. This rigid construction helps maintain cutting precision, making the blade particularly useful for preparing trenches, creating expansion joints and carrying out controlled surface cutting.

Deep U shaped gullets are incorporated between the cutting segments to efficiently remove debris from the cutting area. This design helps maintain cutting speed, reduces material build up and supports smoother operation when working through demanding abrasive surfaces.

For example, a groundwork contractor installing underground drainage beneath an existing asphalt driveway can use the DT20467-QZ to cut clean, controlled lines before removing the surface material.

The aggressive diamond segments provide efficient cutting, while the deep gullets help clear debris and maintain progress. Its extended blade life reduces interruptions for replacements, helping complete excavation preparation more efficiently and reducing consumable costs.

Designed for use with compatible 350mm cut off saws, the blade offers professional cutting performance without compromising durability. Its robust construction makes it particularly suitable for contractors regularly working on road repairs, utility installations, landscaping and groundwork projects.

The DEWALT DT20467-QZ Elite Series Asphalt Diamond Blade is an excellent choice for professionals seeking fast cutting performance, outstanding durability and dependable results in abrasive construction materials.
