The following sections provide detailed overviews of each blade, including design features, recommended uses, and performance notes to help you pick the right tool for your project.
EDiamondTools 14″ All Purpose Diamond Blade
This 14″ blade is designed to tackle hard/reinforced concrete, asphalt, granite, terrazzo, and ductile iron piping. It features a 10mm segment height and 0.125″ segment width, which supports efficient material removal while maintaining core integrity. The broad cutting range makes it suitable for mixed-material site work, reducing the need to switch blades between tasks.
ALSKAR DIAMOND 14″ Heatwave Dry Asphalt Blade
ALSKAR DIAMOND’s 14″ blade is designed for dry cutting when water is unavailable. It’s suitable for asphalt and masonry, with undercut segments to reduce core erosion and extend blade life. This blade is especially useful on lower-horsepower saws where dust control and cooling are key concerns.
EDiamondTools 18″ All Purpose Diamond Blade
The 18″ blade expands cutting depth for heavier materials and larger projects. Like the 14″ model, it targets hard/reinforced concrete and asphalt, with a similar 10mm segment height. A larger diameter helps improve productivity on long straight cuts and helps reduce blade changes on big sites.
Inwell 14 Inch Diamond Dry/Wet Blade
This blade is designed for both dry and wet cutting of asphalt and concrete. It features a 12mm segment height for enhanced durability and a high diamond content for longer life. The design emphasizes precision with a thinner kerf (3.55mm), which minimizes waste and rework on critical cuts.
Delta Diamond Kick-Asphalt 7 Inch Blade
Delta Diamond’s Kick-Asphalt blade uses premium diamond segments designed for asphalt, green concrete, and masonry blocks. The 10mm segments maximize life and reduce cost per cut, while the deep U-gullets promote effective air cooling and chip deflection, supporting cooler operation and longer blade life in demanding conditions.
Buying Guide: Key Purchase Considerations
Blade selection should balance material type, cutting speed, and equipment compatibility. Consider diameter and arbor size to fit your saw, and ensure the blade’s max RPM aligns with your tool. Segment height and width influence cut aggressiveness and heat management; taller, wider segments remove material faster but may wear quickly under heavy loads. For dry-cutting scenarios, choose blades marketed as dry-cut or with undercut segment designs to protect the blade core. In wet-cut applications, ensure your saw’s water delivery system can provide reliable cooling. Finally, assess blade thickness (kerf) to optimize material waste versus cutting precision for your project scale.
Comparative Considerations
- All-Purpose vs. Dry-Cut: All-purpose blades handle mixed materials; dry-cut blades minimize cooling dependence and are ideal where water is not available.
- Diameter and Depth: Larger blades cut deeper in one pass, reducing number of cuts but requiring compatible saws and higher power.
- Segment Design: Undercut or laser-welded segments improve safety and longevity in aggressive cuts and dusty environments.
- Durability vs. Cost: Higher segment height generally increases life under heavy use but can raise upfront cost.
Additional Considerations
When selecting blades for asphalt work, consider job duration, thickness of asphalt or concrete, and whether you will cut in wet or dry conditions. For frequent asphalt cuts, blades with robust segment construction and efficient cooling tend to reduce downtime and rework. If you operate on mixed materials, an all-purpose blade with broad compatibility provides flexibility without frequent blade changes. Always follow manufacturer guidelines for speed and RPM to maximize blade life and cutting performance.
