Dart Red Ten ACS-DUO Diamond Blade 300mm x 20mm – Abrasive, Asphalt & Concrete

The Dart Red Ten ACS-DUO Diamond Blade is a 300mm x 20mm dual-purpose blade designed for cutting abrasive materials, asphalt, macadam, and concrete. Where most blades in this price bracket are made for one material type, the ACS-DUO handles both hard and abrasive surfaces without compromising on speed or blade life. Dart supplies this blade exclusively in the UK, and it is manufactured to the kind of standards that make it a regular choice on busy sites.

The segments are laser welded directly to the steel core. This is not just a manufacturing preference laser welding produces a stronger bond than conventional methods, which means the segments stay where they are supposed to be under sustained cutting loads. For anyone cutting regularly through abrasive materials like gritstone or macadam, that bond integrity matters more than most spec sheets let on.

What Makes the Red Ten ACS-DUO Worth Using

The blade features cooling holes positioned around the core to help with heat dissipation during cutting. Diamond blades generate significant heat, particularly when working through dense concrete or thick asphalt. Without adequate cooling, the steel core can warp and the diamond segments wear unevenly. The cooling holes in the Red Ten ACS-DUO help manage that heat build-up, keeping the blade running straight and extending its working life in demanding conditions.

Fast cutting is another genuine characteristic of this blade. The segment design is built for aggression rather than just longevity, which means jobs get done at a reasonable pace without having to force the machine. That matters when you are cutting kerb lines in asphalt, chasing concrete slabs, or working through grit-based materials where a sluggish blade costs time and adds wear to your equipment.

Abrasive, Asphalt and Concrete in One Blade

The ACS-DUO designation covers three main material categories: abrasive materials such as gritstone and sandstone aggregate, asphalt and macadam surfaces, and general concrete including block paving and slab work. Having a single blade that performs reliably across all three means less time swapping blades on site and fewer spare blades to carry. For groundwork contractors, paviours, and civil engineers, that kind of practical flexibility has a real value.

At 300mm with a 20mm bore, the Red Ten ACS-DUO fits standard angle grinders, cut-off saws, and floor saws with the appropriate bore adapter where needed. It is a straightforward size to work with and widely compatible with common site machines.

The Dart Red Ten ACS-DUO Diamond Blade is a well-made, fast-cutting blade for anyone regularly working with abrasive, asphalt, or concrete materials. It sits at a sensible price point for a blade that genuinely earns its keep across multiple material types, and the laser-welded construction gives confidence that it will hold up through a full day’s cutting rather than giving out halfway through a job.
