Product Specification
4-PIECE NONWOVEN SURFACE CONDITIONING DRUM SET
The Benchmark Abrasives 4-Piece Nonwoven Surface Conditioning Drum Set gives fabricators a complete progression for blending, satin finishing, and final surface refinement without having to buy each drum separately. The set includes four 4-1/2" x 4" nonwoven drums in 80, 120, 180, and 240 grit, making it easy to move from initial cleanup and scratch blending to progressively smoother finishing steps on the same workpiece.
Each drum uses flexible nonwoven surface conditioning material designed to refine rather than aggressively grind the surface. The open-web construction helps conform to flat and contoured areas while producing a controlled, consistent finish, making this set especially useful for oxidation cleanup, weld and fabrication-mark blending, satin finishing, and preparing surfaces for polishing or other final finishing operations.

Features
-
Four-piece finishing progression covers 80, 120, 180, and 240 grit for staged surface refinement.
- Flexible nonwoven construction provides controlled blending and finish refinement without the aggressive stock removal of coated-abrasive sanding drums.
- Includes 80, 120, 180, and 240 grit drums for progressive surface finishing.
- Open-web construction conforms to flat and contoured surfaces for more uniform finishing.
-
Wide 4" working face covers larger areas efficiently and helps reduce the number of passes required.
- Ideal for moving from initial cleanup through satin finishing and finer surface conditioning.
- Designed for compatible portable surface-finishing and drum-sanding machines using the appropriate keyed mounting setup.

Applications & Performance
Designed for progressive surface conditioning from initial blending through finer finish refinement.
- Light oxidation and surface cleanup
- Scratch blending
- Weld and fabrication-mark refinement
- Surface conditioning
- Satin finishing
- Blending machining marks
- Preparing surfaces after sanding or grinding
- Final finish refinement
- Preparing surfaces for polishing or coating
Materials include:
- Steel
- Stainless steel
- Cast iron
- Copper
- Wood
- Fiberglass
- Plastic
- Hard rubber
- Stone
For stainless steel work, keep abrasives used on stainless separate from abrasives previously used on carbon steel to reduce the risk of iron contamination and rust spotting.
Start with the least aggressive grit that will effectively correct the surface, then progress finer until the desired finish is achieved.
Machine Compatibility
Designed for portable surface finishing machines, linear grinders, burnishers, contouring grinders, and drum sanding machines.
Compatible examples include:
-
Eastwood® Contour SCT® (21145)
-
HERCULES® HE68 Surface Conditioning Tool (70979)
-
Metabo® SE 17-200 RT with the appropriate keyed drum arbor
An adapter or additional mounting hardware may be required. Use a setup that securely holds a 4-1/2" diameter x 4" wide drum, allows proper guard clearance, and operates at or below 4,000 RPM.
Safety Tips
- Never exceed the drum's maximum speed of 4,000 RPM. Maximum RPM is a safety limit, not a recommended finishing speed.
- Use dry only.
- Start with light pressure and allow the nonwoven material to work. Excessive pressure can deform the web, generate unnecessary heat, and shorten drum life.
- Avoid dwelling in one area, especially on heat-sensitive workpieces.
- Disconnect the machine from its power source before installing, removing, or inspecting a drum.
- Confirm that the drum is properly seated and securely retained before operation.
- Stop immediately if abnormal vibration occurs and inspect the drum, mounting hardware, and setup before continuing.
- Keep machine guards and auxiliary handles installed as specified by the tool manufacturer.
- Wear appropriate eye, hearing, respiratory, and hand protection for the material and application.
- Secure the workpiece and keep loose clothing, hair, and hands away from rotating components.
- Do not use these wide sanding drums on electric drills.
