A FLEXIBLE GRINDING DISC NEEDS THE RIGHT BACKING PAD
Remove welds, blend surfaces, and deburr with the correct disc system
A resin fiber disc is a coated abrasive with grain resin-bonded to a strong fiber backing. The separate backing pad supports the disc and affects how firmly it contacts the work, so the disc, pad, retainer, guard, grinder, and speed ratings must be treated as one system.
30 live combinations
Three diameters, two abrasive grains, and five grits are listed.

DECISION GUIDE
What should you verify before choosing?
The exact fit, abrasive construction, grit, machine setup, work material, and finish target all affect the result.
Match the disc, backing pad, retainer, and grinder
Choose the diameter specified for the grinder and backing pad. All listed discs have a 7/8-inch arbor hole and require the compatible retaining and guarding system.
Versatile, economical general-metal choice
The original page lists iron, aluminum, copper, stainless steel, and brass. Aluminum oxide is a practical starting choice for routine weld blending, deburring, and surface preparation when the material and process are compatible.
Pressure-responsive choice for demanding alloys
Ceramic grain is designed to fracture and expose fresh cutting edges under an appropriate load. The original page positions it for high-strength stainless, cobalt, other demanding alloys, and casting cleanup such as gates, risers, and parting lines.
From weld removal to surface refinement
Use 24–36 grit for heavier removal, 60 for blending after the heavy cut, 80 for controlled surface preparation, and 120 for finer preparation when the next finish requires it.
RESIN FIBER DISC CONSTRUCTION
What makes a resin fiber disc different from other grinder abrasives?
The abrasive grain, resin bond, fiber backing, backing pad, and grinder all contribute to the cut. A fiber disc is replaceable coated abrasive media; the backing pad supplies the support it does not have by itself.
Grain is bonded across a fiber backing
The exposed abrasive face removes metal while the fiber backing carries the load. Inspect both the abrasive face and backing before every use.
The pad supports the disc under pressure
Use the compatible pad diameter, face density, retainer, and arbor system. A resin fiber disc must not be run unsupported.
Useful for grinding, weld removal, and blending
The coated abrasive face can perform stock removal and then refine the surface through a planned grit progression.
The lowest component rating controls
Confirm the marked ratings for the disc, pad, retainer, and grinder. Never assume one maximum RPM applies to every diameter or accessory combination.
ALUMINUM OXIDE VS. CERAMIC
Which resin fiber disc grain should you choose?
Start with the work material, removal stage, grinder capability, contact pressure, heat, loading tendency, and required finish—not the assumption that the more expensive grain is always better.
Versatile general-metal option
Choose aluminum oxide for economical routine grinding, weld blending, deburring, and surface preparation. Maverick’s original page lists iron, aluminum, copper, stainless steel, and brass among its intended materials.
It is often the practical choice when moderate pressure, broad material coverage, and purchase price matter more than maximum productivity on a hard alloy.
Designed for demanding, pressure-supported cutting
Ceramic grain is engineered to fracture under an appropriate load and expose fresh cutting edges. Maverick positions these variants for high-strength stainless, cobalt, superalloys, gates, risers, parting lines, and other demanding ferrous work.
The grinder and application must supply the right pressure and control; light contact or the wrong setup may not use the grain effectively.
No universal life multiplier is promised. Disc life and cut rate vary with alloy, pressure, contact angle, speed, pad density, heat, loading, and operator technique. The unsupported “3×” and “8×” statements from the old description are intentionally not repeated.
BACKING PAD DECISION GUIDE
What does the backing pad change?
Use only a pad approved for the selected disc and grinder. Pad-manufacturer instructions control, but face density generally changes how firmly the abrasive engages the work.
Firmer support for coarse grinding
A firmer face is commonly used when a coarse grit needs strong, flatter contact for stock removal. It can feel less forgiving near edges and contours.
More compliance for finer grades
A more compliant face is commonly paired with finer grades and blending where some conformity is useful. It is not a substitute for the correct technique.
Every mounting component must match
The disc, pad, retainer, guard, and grinder must accept the same diameter and 7/8-inch arbor system shown in the selector.
Replace worn, distorted, or damaged support
A damaged or uneven pad changes disc support and contact. Inspect it before mounting a new disc and follow its replacement criteria.
GRIT PROGRESSION
What job is each available grit meant to perform?
Choose the least aggressive grit that completes the required removal, then remove its scratch with the next appropriate stage. The exact sequence depends on the metal and final finish.
Heavy weld and stock removal
Use when the process needs the deepest cut in the live range. Control edge digging, heat, and part geometry.
Heavy removal with a smaller scratch
Use for weld leveling and aggressive surface correction when 24 grit is unnecessarily coarse or as the next stage after it.
Blend the heavy grinding stage
Use to reduce the coarse scratch and begin smoothing the transition between a weld area and surrounding metal.
Controlled surface preparation
Use for finer blending and preparation where the next coating, abrasive, or finishing step accepts an 80-grit scratch.
Finer preparation and scratch refinement
Use for the finest scratch offered on this page. It does not replace later finishing media when the specification requires a finer surface.
CHOOSE THE DISC TYPE
Resin fiber disc, flap disc, or bonded grinding wheel?
These accessories are not interchangeable. Confirm the grinder and job are designed for the accessory type you select.
Replaceable coated abrasive on a backing pad
Choose for a low-profile grinding and blending system with separate pad support and a broad grit progression.
Layered abrasive flaps on an integral backing
A flap disc does not use the separate resin-fiber backing pad and produces a different cut, feel, wear pattern, and edge profile.
Self-supporting bonded abrasive wheel
A bonded grinding wheel has different mounting, guarding, use, inspection, and operating requirements. Never substitute one accessory type for another without confirming the complete system.
HOW TO USE IT
Mount the disc on the correct backing pad and verify the system
Follow the grinder, guard, backing pad, flange, and abrasive-disc instructions.
- 01
Disconnect power and confirm the grinder, guard, and backing pad accept the selected diameter and 7/8-inch arbor.
- 02
Inspect the disc and backing pad for damage, wear, contamination, or distortion.
- 03
Mount and secure the disc with the specified flange system; never exceed the lowest component speed rating.
- 04
Run the tool in a safe position and verify smooth operation before contacting the work.
- 05
Use the angle and pressure specified for the disc-and-pad system, keep the tool moving, monitor heat and loading, and replace a damaged or spent disc.
Use the guarding, extraction or collection, personal protective equipment, training, and operating procedures required by the machine, abrasive product, work material, and workplace.
Use it for
- Weld removal and blending on compatible metals
- Deburring and surface preparation
- Ferrous and non-ferrous metals matched to the abrasive
- Gates, risers, parting lines, and casting cleanup
- Compatible right-angle grinders with the correct backing pad
Do not use it for
- Using the disc without a compatible backing pad
- A grinder, guard, flange, arbor, or pad that does not match the disc
- Exceeding the lowest speed rating in the assembled system
- Using a cracked, torn, curled, contaminated, or damaged disc
- Side loading or operating technique prohibited by the grinder or disc instructions
PRODUCT FAQ
Questions before you choose?
What is a resin fiber disc?
It is a coated abrasive disc with abrasive grain resin-bonded to a stiff fiber backing. Unlike a self-supporting bonded grinding wheel or an integral-backed flap disc, it must be mounted on a compatible backing pad and retainer.
What is the difference between aluminum oxide and ceramic resin fiber discs?
Aluminum oxide is the versatile, economical general-metal option on this page. Ceramic grain is designed for demanding, pressure-supported cutting on ferrous and high-strength alloys. Ceramic is not automatically the better choice for every metal, grinder, pressure level, or finish target.
Do resin fiber discs require a backing pad?
Yes. Resin fiber discs are used with a compatible backing pad and the grinder’s specified guard and flange system. Match the disc and pad diameter and follow all component speed ratings.
Which grit should I use for weld removal and blending?
Use 24 or 36 grit for heavier weld and stock removal, then move to 60 for blending, 80 for controlled surface preparation, or 120 for finer preparation. Do not advance until the previous scratch is uniformly removed.
Can I use these discs on aluminum and stainless steel?
The original page lists both aluminum and stainless among the intended metals. Match grain, grit, backing pad, pressure, and loading control to the material. When stainless contamination control matters, dedicate the abrasive and follow the required shop procedure.
What are the shipping and return terms?
Shipping methods, rates, and delivery estimates depend on the order and destination and are shown at checkout. The return policy provides a 30-day window for eligible unused items in original condition and packaging. Restrictions and return-shipping costs apply.
