Diablo DMADS0700 7 in. Segmented Diamond Masonry Cut-Off Blade
Reach for this to dry-cut concrete, brick, or block with a circular saw; it is a masonry grinding blade, not for wood or metal.
| Teeth | Segmented diamond rim (toothless) |
|---|---|
| Arbor | 7/8 in / 5/8 in |
| Kerf | 2.4 mm (~0.094 in) |
| Material | Diamond-segmented rim |
| Diameter | 7 in |
| Best cut | Dry-cut concrete / brick / block |
Diablo D0748F 7-1/4 in. 48-Tooth Steel Demon Ferrous Metal Blade
The go-to when you cut ferrous metal (steel studs, conduit, angle) with a circular saw and want clean, low-spark cuts instead of an abrasive wheel.
| Teeth | 48T TCG |
|---|---|
| Arbor | 5/8 in |
| Kerf | 0.087 in |
| Material | TiCo Hi-Density carbide (cermet) |
| Diameter | 7-1/4 in |
| Best cut | Ferrous metal (studs, EMT, bar) |
Our verdict
Both cut hard material but by opposite mechanisms, so the material decides. The DMADS0700 is a toothless segmented diamond rim that grinds through concrete, brick, and block, and it will not cut metal cleanly. The D0748F Steel Demon has TCG carbide teeth that slice ferrous metal like steel studs and conduit, and it will glaze and burn instantly on masonry. Match the blade to the material: diamond for concrete and masonry, Steel Demon for ferrous metal, and never cross them.
