4-1/2" X 7/8" EXTRA COARSE PAINT & RUST STRIPPING CUP WHEEL - 1 PIECE
The Benchmark Abrasives 4-1/2" x 7/8" extra coarse paint & rust stripping cup wheel is built for aggressive stripping applications where faster removal matters most. Its sharper silicon carbide abrasive grains cut quickly through paint, rust, coatings, adhesives, epoxy, oxidation, and other surface contamination, helping you finish demanding stripping jobs faster.
The open nonwoven nylon web helps shed debris and resist loading while maintaining consistent contact with the work surface. Compared with the standard black stripping wheel, the purple extra coarse version delivers a faster, more aggressive cut for demanding surface-preparation work across fabrication, maintenance, restoration, automotive, and general metalworking applications.

Features & Benefits
Sharper abrasive grains provide a faster, more aggressive stripping action.
Silicon carbide abrasive is effective for paint, rust, oxidation, and coating removal.
Open nonwoven construction helps resist loading and shed debris.
Designed for applications where cutting speed is the priority.
Flexible web follows the work surface better than rigid grinding abrasives.
Removes surface contamination without the heavy stock-removal action of a grinding wheel.
Materials & Applications
Ideal for removing:
Paint
Rust and oxidation
Coatings
Adhesives
Epoxy
Suitable for use on:
Steel
Stainless steel
Cast iron
Aluminum
Copper
Brass
Common applications include fast surface cleanup before welding, refinishing, repainting, coating, or additional abrasive finishing.
Machine Compatibility
Designed for use with properly equipped 4-1/2" angle grinders using the appropriate flange and locknut assembly for a 7/8" center-hole accessory.
For a complete Benchmark setup, consider the Benchmark Abrasives 4-1/2" Corded Angle Grinder (BMT-AGBC4570_1, 11,000 RPM), with the correct mounting hardware and guard clearance for this wheel.
Always confirm the wheel is mounted correctly, the grinder is properly guarded, and the machine's maximum no-load speed does not exceed the wheel's 13,300 RPM maximum rating.
Safety Tips
Never exceed the maximum rated speed of 13,300 RPM.
Inspect the wheel before use and replace it if damaged.
Confirm the wheel is securely mounted before starting the grinder.
Keep the grinder guard properly installed and positioned.
Avoid excessive pressure; allow the abrasive to perform the stripping action.
Test on an inconspicuous area when preserving the underlying finish is important.
Follow all machine and abrasive safety instructions.
Frequently Asked Questions
The Purple Extra Coarse wheel uses sharper abrasive grains for a faster, more aggressive stripping action. It is the better choice when removal speed is the priority.
Choose Purple for aggressive stripping jobs where you want to remove paint, rust, coatings, or other surface contamination as quickly as possible.
Purple is focused on faster, more aggressive cutting. Blue is designed around longer abrasive life with a slower, more controlled cut.
It is designed for removing paint, rust, oxidation, coatings, adhesives, epoxy, and other surface contamination from supported metal surfaces.
It uses silicon carbide abrasive distributed throughout an open nonwoven nylon web.
It is designed for surface stripping rather than heavy stock removal. Because it is still an abrasive product, test first when preserving dimensions or a finished surface is critical.
Use a 4-1/2" angle grinder with a flange and locknut for a 7/8" center hole and a maximum no-load speed of 13,300 RPM or less. The Benchmark BMT-AGBC4570_1 runs at 11,000 RPM. DEWALT DWE402 and Bosch GWS8-45 also meet the diameter and speed requirements; confirm the wheel backing, clamping fit and guard clearance before use.
