4-1/2” SEGMENTED TURBO DIAMOND BLADE WITH STEEL CORE

Built for aggressive cutting through demanding masonry and stone, the Benchmark Abrasives 4-1/2” Segmented Turbo Diamond Blade delivers the cutting efficiency and durability needed for concrete, roofing tile, stone, ceramic, granite, and marble. Its segmented-turbo design is made for users who need fast material removal in a compact blade that can handle a wide range of tough cutting applications.

The open segmented design helps move debris away from the cutting edge and promote cooling during operation, helping maintain cutting efficiency through demanding cuts. Rated for wet or dry cutting and up to 13,580 RPM, this blade combines aggressive cutting performance, broad material capability, and compact 4-1/2” versatility for professional masonry, construction, fabrication, and stone-working applications.

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, mounting opening, and 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.
• Verify the correct mounting configuration and flange arrangement before installation.
• Never enlarge the mounting 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.
