Outside Diameter: 7"
Diamond Thickness: .090"
Arbor Size: 5/8"
Segment Depth: 8mm
Segment Length: 33mm
Total Segments: 14
Grit Size: 40 (Coarse for aggressive material removal)

Applications & Material Compatibility

The segmented design allows for superior air or water circulation, keeping the blade cool during rapid, deep cuts. This wheel is ideal for:

Hard Construction Materials: Cured concrete, reinforced concrete, and heavy masonry.
Natural Stone: Granite slabs, basalt, quartzites, and hard sandstone.
Refractory Materials: High-density firebrick and industrial ceramics.
Abrasives: Green concrete and asphalt-over-concrete applications.

Equipment Compatibility

Featuring a standard 5/8" arbor, this wheel is compatible with:

7" Circular saws and Worm Drive saws.
Handheld high-speed power cutters and gas saws.
Table saws and masonry saws.
Right-angle grinders (ensure proper guarding and RPM compatibility for segmented blades).

Condition Disclosure

Used Condition: This is a used industrial wheel. While it has been previously operated, it remains in solid working condition with plenty of life left in the 8mm diamond matrix.
Surface Wear: As shown in the high-resolution photos, the wheel exhibits signs of professional use and industrial storage. This includes surface debris on the diamond segments and hub, as well as scratches and cosmetic wear on the gold-tone metal hub. These factors are strictly aesthetic and will not impact the wheel's structural integrity or cutting efficiency.

Get professional-grade, American-made cutting power at a fraction of the retail cost. Perfect for contractors or heavy-duty industrial projects.
