Diamond Metal Cutting Wheels

For general metal cutting, a vacuum-brazed continuous rim blade like the Metal Maniac Diamond Blade works well for stainless steel, rebar, cast iron, aluminum, and sheet metal. For ductile iron pipe specifically, a laser-welded turbo segment blade with a specialized diamond matrix formula and core protection delivers smoother, pinch-free cuts.

Laser-welded turbo or continuous rim diamond blades are best for cutting steel. Turbo segment designs provide fast, smooth cuts on rebar and angle iron, while continuous rim vacuum-brazed wheels offer extreme durability and reduced dust for sheet metal and structural steel applications on angle grinders.

A vacuum-brazed diamond disc with a solid steel body is often the best choice for metal, lasting up to 65 times longer than standard abrasive wheels while reducing breakage risk, odor, and dust. Laser-welded diamond blades with specialized matrices for ductile iron or rebar are ideal for heavier-duty pipe and rebar cutting.

Vacuum-brazed diamond metal cutting wheels can last up to 65 times longer than standard abrasive cutoff wheels, since the diamond segments don't wear down or shrink the way abrasive material does. This results in significantly lower cost per cut over the life of the wheel, especially in high-volume cutting operations.

Many diamond metal cutting blades, particularly laser-welded turbo segment designs, can run wet or dry depending on the application and equipment. Vacuum-brazed continuous rim wheels used on angle grinders are typically designed for dry cutting only, so always check the manufacturer's specifications before use.

Diamond metal cutting wheels are available in a range of diameters from 4.5 inches for angle grinders up to 16 inches or larger for walk-behind and table saws, with common arbor sizes including 7/8"-5/8", 1"-20MM, and 20MM to fit various saws and grinders used in metal fabrication.
