Will a diamond blade cut metal? The blades here are made for tile and masonry, not metal, so compare the 4.5 and 7 inch blades on rim type, arbor and max RPM.

Will a diamond blade cut metal? No, not the blades in this guide: every listing here is made for tile and masonry, and none of them states metal. A diamond blade grinds through porcelain, ceramic, granite, marble, concrete, brick and stone, and the segmented and continuous rims in this guide are shaped for those materials. If the job is metal, the blade you need is a different kind, so read the listing and your grinder manual before you mount anything.

Will a diamond blade cut metal? What the listings say
The short answer is no for the blades in this guide. The ZORUNNA blades state porcelain, ceramic, granite, tile and marble. The DEWALT blade states block and brick. The EZARC blade states granite, concrete, sandstone and limestone. None of the 4 listings states metal, so none of them is listed for cutting metal.
Rim shapes: continuous, turbo mesh and segmented
The DEWALT blade has a continuous rim and is listed for block and brick. The ZORUNNA blades have an X-teeth turbo mesh rim and are listed for tile with less chipping. The EZARC blade is segmented, and the gaps between the segments let air flow, clear debris and keep the disc cool.
A segmented rim cuts aggressively through masonry, while the turbo mesh rim cuts tile with less chipping. Match the rim to the material, not to the grinder.
| Blade | Size | Rim | Made for | Max RPM |
|---|---|---|---|---|
| ZORUNNA 5-Pack 4.5 | 4.5 in | X-teeth turbo mesh | Porcelain, ceramic, granite, tile, marble | 13,200 |
| ZORUNNA 2-Pack 4.5 | 4.5 in | X-teeth turbo mesh | Porcelain, ceramic, granite, tile, marble | 13,200 |
| DEWALT DW4712 7-Inch | 7 in | Continuous | Block and brick | Not stated |
| EZARC 4.5 Segmented | 4.5 in | Segmented | Granite, concrete, sandstone, limestone | 13,300 |
Arbor, size and speed
The ZORUNNA and EZARC blades fit a 7/8 inch arbor, and 3 of them measure 4.5 inches across. The DEWALT blade is 7 inches and states no arbor size. The ZORUNNA blades list a max of 13,200 RPM and the EZARC lists 13,300 RPM, so check the max RPM on the listing against your grinder before you mount a blade.

If the job is metal
