Diamond Concrete Circular Saw Blades

A laser-welded segmented or turbo diamond blade is typically best for cutting concrete with a circular saw. These blades offer durable segments, undercut protection, and can run wet or dry. Bond hardness should be matched to your concrete's aggregate hardness for optimal cutting speed and blade life.

You need a diamond blade rated for concrete, with segment and bond type matched to whether the concrete is green (freshly poured) or cured. Early entry blades suit green concrete, while laser-welded segmented or turbo blades with harder bonds are better for cured, reinforced concrete.

Early entry blades are designed for cutting green concrete shortly after placement, minimizing raveling and spalling, and require a matching skid plate accessory. Standard laser-welded blades are intended for cured concrete, masonry, and asphalt, offering more aggressive segments for harder, fully set materials.

Many multi-purpose laser-welded diamond blades, such as turbo or U-slot designs, are rated to cut through rebar embedded in reinforced concrete. Check the product specifications for rebar compatibility, as dedicated concrete-only blades may wear faster or perform poorly when encountering steel reinforcement.

Most segmented and turbo diamond blades in this category are rated for both wet and dry cutting. Wet cutting reduces dust and heat, extending blade life, while dry cutting offers convenience for smaller jobs. Confirm the specific blade's wet/dry rating before beginning your cut.

Blade diameter should match your saw's maximum blade capacity and the depth of cut required for your slab or material thickness. Diameters range from 6" for early entry saws up to 24" for large walk-behind saws, with 12"-16" being common for most job site circular and table saw applications.
