Product Specification
6" X 1" X 1" CONVOLUTE DEBURRING WHEEL 9SF
The Benchmark Abrasives 6" x 1" x 1" Convolute Deburring Wheel 9SF combines Fine silicon carbide abrasive with the hardest construction in Benchmark's 7SF, 8SF, and 9SF lineup. Use it for controlled deburring, parting-line cleanup, and blending where a firmer wheel suits the job.
9SF combines hardness 9 with Fine-grade silicon carbide abrasive. The number identifies hardness, not sandpaper grit.

Important: 9SF identifies the wheel's grade and hardness configuration. The “9” is not a conventional sandpaper grit size.
Applications & Performance
- Controlled deburring of cut, punched, and machined edges
- Blending machine and belt marks
- Finishing and edge cleanup on small metal parts
- Removing residual parting lines from castings and forgings
- Smoothing sharp edges and radii on stamped components
- Deburring stainless steel pipe threads and punched holes where wheel access allows
- Blending and polishing around prepared weld areas
- Finishing molds, dies, and precision metal components
- Harder 9SF construction provides another option when more edge support is desired
- Evaluate the wheel on a representative part before specifying the final finish
Use light to moderate pressure and allow the abrasive wheel to work. Excessive pressure can reduce control and may damage the workpiece.
Materials
Suitable applications include:
- Steel
- Stainless Steel
- Cast Iron
- Wrought Iron
- Titanium
- Nickel and Nickel Alloys
- Aluminum
- Copper
- Brass
- Tin
- Other compatible nonferrous metals and alloys
Machine Compatibility
For bench and pedestal deburring or polishing machines that accept a 6" diameter x 1" wide wheel with a 1" arbor hole and suitable mounting hardware. Stay within the lower speed limit of the wheel and machine.
Compatible examples include:
-
Burr King® Model 600 Fixed-Speed 60100 with WA1 Wheel Adapter
-
Burr King® Model 600 Variable-Speed 61110 with WA1 Wheel Adapter
The WA1 adapter provides the 1" mounting arbor for these examples. Confirm wheel seating, retaining hardware, guard clearance, and rotation direction before use.
For other machines, check wheel width, arbor fit, mounting hardware, and guard clearance as well as diameter.
Choosing Between 7SF, 8SF & 9SF
Benchmark Abrasives offers these Fine silicon carbide convolute wheels in hardness levels 7, 8, and 9.
Not sure where to start? Try 8SF, check the edge and finish, then choose 7SF for a softer wheel or 9SF for a harder option.
All three options use Fine-grade silicon carbide abrasive; hardness is the main choice within this lineup.
Safety Tips
- Never exceed the wheel's maximum speed of 6,000 RPM.
- Mount the wheel so it rotates in the direction indicated by the rotation arrow.
- Verify the wheel diameter, width, arbor, mounting hardware, spindle engagement, guards, and work-rest clearance before operation.
- Use only approved flanges, adapters, and reducing hardware appropriate for the complete machine and wheel setup.
- Apply light to moderate working pressure rather than forcing the wheel into the workpiece.
- Inspect the wheel before each use and do not operate a damaged wheel.
- Wear safety glasses and appropriate face protection, plus hearing, respiratory, and hand protection suited to the task and machine instructions.
- Keep machine guards properly installed and follow the machine manufacturer's operating instructions.
- Water or water-soluble oil may be used with the wheel only when the machine and complete setup are specifically approved for wet operation.
