Product Description

The RLT 4-1/2" Terrazzo & Concrete Diamond Blade is a high-performance cutting accessory for professional-grade results in tough masonry materials. This blade is formulated for cutting terrazzo, reinforced concrete, marble, granite, slate, and other engineering materials, making it essential for contractors, masons, and DIY enthusiasts tackling flooring, tiling, or construction projects. Its segmented rim design, combined with a high-strength steel core and metallurgically bonded diamond segments, ensures fast, efficient cutting and exceptional durability.

What Materials Can This RLT Diamond Blade Cut?

This blade is optimized for a variety of hard, abrasive surfaces. Terrazzo is ideal for scoring, repairing, or cutting through terrazzo flooring. Reinforced concrete is effectively cut, even with rebar. Marble and granite suit precision cuts on stone slabs and tiles. Slate and engineering materials cut through other dense masonry materials.

How Does the Segmented Rim Design Improve Performance?

The segmented design provides faster cutting action and more efficient heat dissipation compared to continuous rim blades. Gaps between segments allow improved cooling and debris removal, crucial when cutting dense materials like concrete and terrazzo. This prevents overheating, extends service life, and maintains smooth, aggressive cutting action.

Is the RLT Diamond Blade Easy to Use with My Angle Grinder?

Yes. The blade features a standard 7/8-inch arbor fitting virtually all major brands of 4-1/2" angle grinders. It is engineered for dry cutting, allowing maximum portability and ease of use without water supply. Maximum operating speed is compatible with the typical 10,000-12,000 RPM range of standard angle grinders.

What is the Size and Compatibility of This Blade?

Diameter is 4-1/2 inches. Arbor size is 7/8 inch. Compatibility is designed for standard 4-1/2" angle grinders.

How Does This Blade Compare to Other Diamond Blades?

The RLT blade is formulated for hard masonry, balancing cutting speed and durability. Like other general-purpose concrete blades, it features diamond segments laser-welded to a steel core for longevity. However, its positioning as a terrazzo blade suggests formulation optimized for the unique, abrasive nature of terrazzo and similar engineered stones, which may require a different diamond bond than a standard concrete blade.
