Turn your angle grinder into a versatile polishing tool with our 4-1/2" x 7/8" T27 felt polishing flap disc. The layered felt construction provides a broad, conformable polishing face that works well on flat, curved, and irregular surfaces, while the familiar flap-disc format gives you the speed, control, and portability of a standard 4-1/2" angle grinder.
This felt disc can be used throughout the cut → polish → finish sequence by changing buffing compounds. Unlike an abrasive flap disc with a fixed grit, the felt itself does not determine the polishing stage—the compound does. Use a cutting compound for initial refinement, progress through intermediate compounds to develop luster, and finish with a fine compound for high-gloss or mirror polishing.

Product Features
Felt flap construction designed specifically for angle-grinder polishing.
Can be used throughout the cut → polish → finish sequence by changing compounds.
Broad 4-1/2" face provides efficient coverage on medium to large surfaces.
Layered felt conforms well to curves, contours, and irregular workpieces.
T27 flat-face design works well on flat surfaces and outside contours.
No fixed abrasive grit—the compound determines the level of cut and finish.
Works with cutting, intermediate, coloring, and finishing compounds.
Convenient alternative when the workpiece is difficult to bring to a stationary buffer.
Maximum operating speed of 13,300 RPM.
Machines Used On
Designed for:
4-1/2" angle grinders
5" angle grinders using a compatible 7/8" arbor setup
The felt flap-disc format is especially useful when you want to perform a complete polishing process with the same handheld angle grinder platform rather than moving the workpiece between stationary buffing machines.

Tip: The felt disc is the polishing media; the compound controls the stage. Changing compounds allows the same style of felt flap disc to move from initial polishing through intermediate refinement and into final high-gloss finishing.
For best results, dedicate one felt disc to each compound to prevent cross-contamination between polishing stages.
Safety Tips & Techniques
Never exceed the 13,300 RPM maximum operating speed.
Confirm the disc is properly mounted before starting the grinder.
Use an angle grinder and mounting system compatible with the 7/8" arbor.
Apply compound sparingly rather than heavily loading the felt.
Use light to moderate pressure and allow the compound and felt to do the work.
Keep the disc moving to control heat buildup.
Clean the workpiece before changing compounds.
Use a separate felt disc for each compound whenever possible.
No. Felt can be used throughout the complete polishing sequence. The compound determines whether the disc performs an initial cutting, intermediate-polishing, coloring, or final-finishing role.
Yes. When paired with an appropriate cutting compound, the felt flap disc can perform the initial polishing stage before moving to progressively finer compounds.
The felt acts as the polishing media and compound carrier. Much of the actual cutting and finishing action comes from the compound, so changing compounds changes how the polishing system performs.
A felt flap disc lets you perform multi-stage polishing with a portable angle grinder. It is especially useful on larger workpieces, installed components, curved surfaces, and assemblies that are difficult to bring to a bench buffer.
No. They are different polishing systems designed around different tools. Felt flap discs are the appropriate polishing media for angle-grinder systems, while conventional cotton and flannel wheels are designed around drills, bench buffers, and polishing motors. Both can accomplish a complete multi-stage polish.
Yes. This disc contains no abrasive grain. The selected compound provides the cutting and polishing action.
Yes. We recommend one disc per compound to prevent coarse compound residue from contaminating finer polishing stages.
The disc is well suited for stainless steel, steel, aluminum, brass, copper, and other compatible metals. It can also be used on compatible plastics with the appropriate compound and careful heat control.
The disc has a 7/8" arbor and is designed for compatible 4-1/2" and 5" angle grinders.
