Product Specification
4-1/2” HOT PRESSED SINTERED TURBO DIAMOND BLADE
Built for fast, controlled cutting across hard masonry and stone, the Benchmark Abrasives 4-1/2” Hot Pressed Sintered Turbo Diamond Blade is designed for granite, marble, concrete, reinforced concrete, engineering brick, hard clay roof tile, and masonry. Its turbo-style diamond rim provides more continuous cutting contact than an open segmented blade, helping balance aggressive material removal with a more controlled finished edge.
The hot-pressed sintered design is paired with a 7 mm diamond rim for versatile dry-cutting performance across demanding construction and stone applications. With a 7/8" / 5/8" arbor configuration and a maximum operating speed of 13,580 RPM, this compact 4-1/2” blade offers the maneuverability needed for trimming, installation, repair, and general-purpose cutting work.

Safety Tips
- Never exceed the blade’s maximum rated speed of 13,580 RPM.
- This blade is intended for dry cutting only.
- Inspect the blade, turbo rim, arbor opening, and mounting flanges before each use.
- Do not use a damaged, cracked, bent, or distorted blade.
- Match the 7/8" / 5/8" arbor configuration to the machine’s approved mounting arrangement.
- Never enlarge the arbor opening or use improvised or loose reducing bushings.
- Use the cutting guard and flange system specified by the machine manufacturer.
- Allow the blade to cut at its own rate rather than forcing it through the material.
- Follow required cooling intervals during dry cutting.
- 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.
- Dry cutting concrete, brick, tile, granite, marble, and other silica-containing materials can generate respirable silica dust. Use task-appropriate dust-extraction controls.
