4.5” LASER WELDED SEGMENTED DIAMOND BLADE WITH STEEL CORE

Built for fast, aggressive cutting through tough masonry and stone, the Benchmark Abrasives 4.5” Laser Welded Segmented Diamond Blade gives contractors, fabricators, and serious users a durable cutting solution for concrete, roofing tile, stone, ceramic, granite, and marble. Laser-welded diamond segments are securely bonded to a strong steel core to handle demanding cutting applications while maintaining dependable performance throughout the life of the blade.

The segmented rim is designed to move debris out of the cut and improve airflow around the cutting edge, helping control heat and maintain cutting efficiency during heavy material removal. Rated for wet or dry cutting and up to 13,580 RPM, this blade combines versatility, durability, and aggressive cutting performance in a compact 4.5” format.

Machine Compatibility

For use with angle grinders and masonry-cutting equipment that accept a 4.5" diamond blade.

Compatible examples include:

• Benchmark Abrasives 4-1/2" Corded Angle Grinder (BMT-AGBC4570_1) — 11,000 RPM; dry cutting with 7/8" mounting.
• Makita® 9557PB — dry cutting with the 135103-2 cut-off guard.
• Makita® 9557PBX1 — dry cutting; 135103-2 cut-off guard included in the kit.
• DEWALT® DWE402 — dry cutting with a Type 1/41 cutting guard, sold separately.

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 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. 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.
