7” LASER WELDED SEGMENTED DIAMOND BLADE WITH STEEL CORE
Built for fast, aggressive cutting through tough masonry and stone, the Benchmark Abrasives 7” Laser Welded Segmented Diamond Blade delivers the durability and cutting efficiency needed for demanding concrete, roofing tile, stone, ceramic, granite, and marble applications. Laser-welded diamond segments are securely bonded to a strong steel core to provide dependable cutting performance under heavy use.
The segmented rim is designed to move debris out of the cut and promote airflow around the cutting edge, helping manage heat and maintain cutting efficiency during material removal. Rated for wet or dry cutting and up to 8,700 RPM, this 7” blade combines aggressive cutting action, versatile material capability, and durable construction for professional masonry and stone work.

Machine Compatibility
For use with angle grinders and masonry-cutting equipment that accept a 7" diamond blade.
Compatible examples include:
Makita® GA7021 — dry cutting with the 122914-4 cut-off guard.
Match the arbor and speed rating, and use the tool’s specified mounting hardware and cutting guard with clearance for the blade. Follow the blade and tool instructions for wet or dry use.
Safety Tips
Never exceed the blade’s maximum rated speed of 8,700 RPM.
Inspect the blade, steel core, arbor opening, and mounting flanges before each use. Do not use a damaged or distorted blade.
Use the cutting guard required by the machine manufacturer. A standard grinding guard may not be suitable for diamond cutting.
Match the arbor and flange system to the machine. Never enlarge the arbor opening or use improvised or loose reducing bushings.
Only cut dry when both the blade and machine permit dry operation.
When dry cutting, follow the blade and machine manufacturer’s required cooling intervals.
Do not side-load or grind with the sides of the blade unless the exact accessory is specifically approved for that operation.
Use appropriate eye, hearing, respiratory, and other required personal protective equipment.
Concrete, masonry, and stone cutting can generate respirable silica dust. Use task-appropriate water-delivery or dust-extraction controls for the application.

Frequently Asked Questions
It is intended for cutting concrete, roofing tile, stone, ceramic, granite, and marble.
Yes. The blade is rated for wet or dry cutting, but the machine must also permit the selected operating method. Never introduce water to a tool designed for dry use only.
The blade uses a diamond knockout with 7/8" and 5/8" arbor configuration. Always verify the required mounting setup and flange system for your machine.
Compatible examples include: Makita® GA7021 can be used for dry cutting with the 122914-4 cut-off guard. Other models may also fit; see Machine Compatibility for setup guidance.
No. Diameter alone does not determine compatibility. Arbor configuration, flanges, guard requirements, blade RPM, clearance, and the machine manufacturer’s approved cutting setup must all match.
The spaces between the segments help clear debris from the cut and promote cooling around the cutting edge, making segmented blades well suited for aggressive masonry cutting.
No. Segmented blades generally prioritize cutting efficiency and debris clearance, while continuous-rim blades are typically selected when a smoother finished edge is more important.
