Dewalt DX3981 Laser Blades Evolution Hybrid Rim Blades / Marble And Granite - D230XBS22.2

Key specs include a 22.2 mm cutting diameter, laser-welded segments for stability, and a capable RPM range up to 4000 RPM. It’s designed for contour cutting on stone materials and is compatible with several saw machines.

It's optimized for marble, granite, and related stone materials such as sintered stone and agglomerates, making it suitable for countertop fabrication, tile work, and trim cuts.

Use it for contour cuts, edge profiling, trimming granite or marble, and other precise stone-cutting tasks where minimizing chipping and achieving clean edges is important.

Mount the blade on compatible saws with a 22.2 mm bore, ensure the arbor is secure, and confirm your tool’s RPM rating supports up to 4000 RPM. For best results, use proper PPE, keep guards in place, and use water for cooling during wet cutting.

The DX3981 uses a tungsten carbide edge in a laser-welded hybrid rim design, which can offer good durability and cleaner cuts with potentially lower cost per cut for certain marble/granite jobs. Diamond blades typically excel in hardness and cutting speeds on certain materials but can wear differently depending on the stone and setup.

It's well-suited for fabricators shaping marble or granite countertops, installers performing contour work around sinks or edges, and any project requiring precise cuts with reduced chipping in natural stone.

Yes. Always wear eye protection and gloves, keep hands away from the blade, ensure guards and safety devices are in place, avoid overheating by using proper feed rate and coolant/water when wet cutting, and only use the blade on saws that meet or exceed the listed RPM rating.

Blade life and performance are influenced by cutting speed, feed rate, material density, and cooling. To maximize life, use appropriate RPM, avoid aggressive feeds that cause overheating, keep the blade clean from residue, and use water when wet cutting to reduce heat buildup.

This blade combines a carbide edge with a laser-welded rim for durability and precision in marble and granite cuts. It’s designed to reduce chipping, support versatile wet/dry use, and work across compatible tools, offering long-term cutting performance for stone fabricators and installers.
