Benchmark Abrasives 7" ceramic resin fiber discs deliver fast, aggressive stock removal and extended cutting life for demanding grinding applications. Engineered ceramic abrasive continuously micro-fractures under grinding pressure to expose fresh cutting edges, helping the disc maintain a strong cutting rate on stainless steel, high-nickel alloys, titanium, super alloys, and other difficult-to-grind metals.
Each disc combines premium ceramic abrasive with a heat-resistant resin bond and heavy-duty vulcanized fiber backing. The rigid backing supports the abrasive under pressure and helps transfer power efficiently to the workpiece for rapid material removal. Ceramic's cooler-cutting action makes it especially useful on heat-sensitive metals where excess heat can cause discoloration. Available in 24, 36, 50, 60, 80, and 120 grit, these larger 7" discs cover heavy grinding through blending and surface preparation.
These discs are designed for use on 7" right-angle grinders with a compatible 7" backing pad. A backing pad is required and sold separately.

Product Features
Premium ceramic abrasive for rapid stock removal and demanding grinding
Self-sharpening ceramic grain micro-fractures to continually expose fresh cutting edges
Excellent cutting speed and extended abrasive life under sustained grinding pressure
Cooler-cutting performance helps reduce heat buildup and workpiece discoloration
Heat-resistant resin bond withstands demanding grinding conditions
Heavy-duty vulcanized fiber backing provides strong support and efficient pressure transfer
Resistant to heat, glazing, and loading
Larger 7" diameter provides greater working surface for larger grinding applications
Excellent choice for stainless steel, titanium, nickel, and super alloys
Wide grit range for heavy grinding through blending and surface preparation
7/8" center hole for use with compatible right-angle grinder backing pads
Always make sure the disc, backing pad, and grinder are compatible in diameter, arbor, and operating speed. Never exceed the maximum RPM of the lowest-rated component in the system.
Applications
Ideal for demanding grinding and surface preparation applications including:
Heavy stock removal
Weld removal and weld leveling
Weld blending
Beveling and edge preparation
Deburring
Shaping and contouring
Rust and corrosion removal
Paint and coating removal
Cleaning and surface preparation
Blending and smoothing
Larger surface grinding applications
Materials
Commonly used on:
Carbon Steel
Stainless Steel
Cast Iron
Titanium
Nickel
Wrought Iron
High-Nickel Alloys
Super Alloys
Copper
Brass
Tin
Wood
Fiberglass
Plastics and Composites
The current Benchmark listing specifically supports ferrous materials including cast iron, steel, stainless steel, titanium, nickel, wrought iron, and super alloys, plus copper, brass, and tin, and also describes use on wood, fiberglass, plastics, and composites.
Tip: Ceramic abrasive is designed to fracture and expose fresh cutting edges under grinding pressure. Consistent working pressure helps activate this self-sharpening action and maintain cutting efficiency.
Aluminum Oxide vs. Zirconia vs. Ceramic
Aluminum Oxide
Aluminum oxide is the economical choice for general-purpose grinding and everyday shop work.
Zirconia
Zirconia offers a step up in durability and cutting performance, making it well suited to sustained grinding, fabrication, and heavier stock removal.
Ceramic
Ceramic is the premium choice for demanding production grinding, stainless steel, titanium, high-nickel alloys, and applications where cutting speed, cooler grinding, and abrasive life are the priority.
For users working on difficult metals or high-production applications, Ceramic provides the strongest performance advantage of the three.
Safety Tips & Techniques
Always use a compatible backing pad specifically designed for resin fiber discs.
Inspect the disc and backing pad before use. Do not use damaged, cracked, torn, or moisture-compromised discs.
Never exceed the maximum RPM marked for the disc, backing pad, or grinder.
Keep the grinder guard properly installed and positioned.
Apply consistent working pressure to help activate the ceramic grain's self-sharpening action.
Keep the grinder moving across the workpiece to distribute heat and prevent gouging.
Store fiber discs in a clean, dry environment to protect the backing from moisture and damage.
Frequently Asked Questions
These discs are designed for demanding grinding applications including heavy stock removal, weld removal, weld leveling, beveling, deburring, shaping, blending, and surface preparation. The larger 7" diameter is especially useful on larger work areas and production grinding applications.
Ceramic abrasive is an engineered grain that micro-fractures during grinding to continually expose fresh cutting edges. This helps maintain aggressive cutting performance and extended abrasive life.
Choose Ceramic when maximum cutting speed, abrasive life, cooler grinding, and productivity are the priorities. Zirconia is an excellent step-up abrasive, but Ceramic provides the greater advantage in demanding, high-pressure grinding applications.
Yes. These discs require a compatible 7" x 5/8"-11 resin fiber disc backing pad for use on a compatible right-angle grinder.
Yes. Ceramic abrasive is particularly well suited to stainless steel because its fast cutting action helps reduce unnecessary heat buildup while maintaining a strong cutting rate.
Yes. Ceramic abrasive is an excellent choice for titanium, nickel, high-nickel alloys, and super alloys because these difficult-to-grind materials benefit from fast cutting and reduced heat generation.
No. These 7" Ceramic Resin Fiber Discs are for dry use only. Do not use them wet.
These 7" Ceramic Resin Fiber Discs are available in 24, 36, 50, 60, 80, and 120 grit.
The maximum rated speed for these 7" Ceramic Resin Fiber Discs is 8,600 RPM. Never exceed the rated speed of the disc, backing pad, or grinder.
Not necessarily. Aluminum Oxide is often the best value for general-purpose work, while Zirconia provides excellent durability for sustained grinding. Ceramic provides the greatest benefit in demanding applications where cutting speed, difficult materials, and abrasive life justify the premium.
