Diamond Blades for Angle Grinders

J-slot blades have slots around the rim that dissipate heat and clear debris, ideal for chip-free tile and stone cuts. Continuous rim blades have a solid edge for the smoothest cuts, commonly used on metal, and often designed for dry-only cutting applications.

Yes, but blade design differs by material. Vacuum-brazed continuous rim blades are built specifically for metal cutting—stainless steel, rebar, cast iron, and sheet metal—while J-slot blades are optimized for porcelain, ceramic, granite, and marble cutting.

Not always. Some blades are designed for wet or dry use, while others, like continuous rim metal-cutting blades, are dry-only. Wet cutting reduces dust and heat buildup, but always follow the manufacturer's recommended cutting method for your specific blade.

Most angle grinder diamond blades use a 7/8"-5/8" arbor, common across 4", 4.5", 5", 7", 8", and 10" diameters. Confirm your grinder's spindle size before purchase, as an improper fit can compromise cutting safety and performance.

Diamond blades, particularly vacuum-brazed designs, can last up to 65 times longer than standard abrasive cutoff wheels. They resist shrinking with use, maintain consistent diameter over time, and reduce overall tool and material replacement costs on the job site.

Yes, solid steel-bodied diamond blades reduce breakage risk compared to thin abrasive wheels, making them a safer choice for demolition and fabrication. They also produce less dust and odor, improving working conditions during extended cutting tasks.
