Built for fast, aggressive cutting across common masonry materials, the Benchmark Abrasives 4-1/2” 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 work.
The 10 mm diamond segments provide substantial usable cutting depth, while the 4-1/2” diameter offers a strong balance of cutting capacity and maneuverability for handheld applications. With a 7/8" / 5/8" arbor configuration, wet or dry capability, and a maximum speed of 13,580 RPM, this blade delivers the versatility and aggressive material removal expected from a premium general-purpose diamond blade.

Machine Compatibility
For use with 4-1/2” angle grinders.
Compatible examples include:
Benchmark Abrasives 4-1/2" Corded Angle Grinder (BMT-AGBC4570_1) — 11,000 RPM; dry cutting with 7/8" mounting and the appropriate diamond cutting guard.
Other models may also fit. Match the mounting, speed rating and required guard to your tool.
Safety Tips
Never exceed the blade’s maximum rated speed of 13,580 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 7/8" / 5/8" arbor 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.
