When a flatwork crew needs to score control joints, trench for utilities, or open up a slab for repair, the EDCO HG1812V3 18-inch concrete blade is the cutting edge that keeps an EDCO DS-18 walk-behind saw productive all day. Built for concrete contractors, masons, and rental fleets working cured concrete and paver brick, this general-purpose diamond blade pairs OptiCut technology with laser-welded segments so operators get fast, straight cuts with low vibration and a long, predictable service life.
The HG1812V3 is engineered specifically for the 18-inch EDCO DS-18 saw, so the 1-inch arbor and .125-inch kerf drop in without spacers or guesswork. American-made construction and advanced heat dispersion let the blade run cooler under sustained load, which protects the segments and holds cutting speed deep into the job.
For the best results, run the HG1812V3 with water on cured slabs to control silica dust and extend segment life, set cut depth in passes on deep work, and let the saw and blade speed do the cutting rather than forcing the feed. Treated this way, a general-purpose segmented blade like the HG1812V3 keeps straight, square cuts coming through driveways, slabs, and paver fields without the chatter or premature wear that comes from overheating.

Frequently asked questions
What saw does the HG1812V3 fit?
It is sized for the EDCO DS-18 18-inch walk-behind saw, with a 1-inch arbor that matches the DS-18 spindle. It also fits any 18-inch saw that uses a 1-inch arbor.
Can it cut green concrete and asphalt, or only cured concrete?
The HG1812V3 is optimized as a general-purpose blade for cured concrete and paver brick. For dedicated green-concrete or asphalt work, EDCO offers universal and application-specific blades better matched to those materials.
Is this a wet-cut or dry-cut blade?
Laser-welded segmented blades like the HG1812V3 can be run wet or dry. Wet cutting controls dust and extends blade life, which is the common practice on cured concrete slabs.
Why choose a segmented blade for concrete?
Segmented blades cut faster and run cooler than continuous-rim blades because the gullets between segments clear slurry and pull in air, making them the standard choice for aggressive cured-concrete cutting.
Are EDCO diamond blades made in the USA?
Yes. EDCO diamond tooling, including the HG1812V3, is manufactured in the United States to EDCO's performance standards.
