Built for fast, aggressive cutting across common masonry materials, the Benchmark Abrasives 7” Premium Segmented Diamond Blade is a versatile general-purpose choice for block, concrete, pavers, and brick. Its segmented diamond rim is designed to clear debris efficiently and promote cooling, helping maintain productive cutting performance through demanding construction, masonry, and repair applications.
The 10 mm diamond segments provide substantial usable cutting depth, while the larger 7” diameter delivers increased cutting capacity over smaller handheld blades. With a diamond knockout / 7/8" / 5/8" mounting configuration, wet or dry capability, and a maximum speed of 8,700 RPM, this blade combines versatility, cutting depth, and aggressive material removal for professional general-purpose masonry work.

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.
Match the blade’s mounting configuration to the machine’s approved flange arrangement.
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, brick, block, and paver cutting can generate respirable silica dust. Use task-appropriate water-delivery or dust-extraction controls.
