Web Discs

Web Discs (Surface Conditioning Discs) for Australian Metal Finishing

Web discs (also called surface conditioning discs or non-woven abrasive discs) are flexible non-woven synthetic abrasive discs used for surface conditioning, blending, finishing, and producing decorative finishes on stainless steel, aluminium, and other metals. Different from coated abrasive discs (which use grit bonded to a backing), web discs use abrasive grit embedded in a synthetic non-woven structure that flexes and conforms to the work surface. For Australian fabricators, metal finishers, and stainless steel workers, web discs deliver finish quality coated abrasives can't match. AIMS Industrial supplies web discs across the grades and sizes Australian customers actually use.

How web discs differ from coated abrasive discs

• Coated abrasive discs — grit bonded to paper or cloth backing; aggressive cutting, fixed cutting depth
• Web discs (non-woven) — grit embedded in synthetic web; gentler cutting, conforms to surface contours, produces uniform decorative finishes

Web discs are the right choice when surface finish quality matters more than stock removal speed, when the surface has contours or features that flat discs would damage, and when blending between different finished surfaces.

The web disc grades we stock

• Coarse (grey/maroon) — heavy paint and rust removal, surface preparation
• Medium (red/maroon) — general surface conditioning, finish blending
• Fine (grey/grey) — fine finishing, polishing preparation, decorative finishing
• Very fine (white) — final finishing, satin finishes

Where web discs earn their place

• Stainless steel finishing — producing satin and brushed finishes on fabricated stainless
• Aluminium surface conditioning — preparing aluminium for finishing without aggressive grit marks
• Weld blending — blending welds into surrounding finished surfaces
• Decorative metal finishing — producing consistent decorative finishes for visible work
• Surface preparation before painting — keying surfaces without leaving aggressive scratch patterns
• Restoration and refinishing — restoring original finishes on damaged metalwork

Sizing — match to backing pad and equipment

Web discs come in standard sizes:

• 50mm and 75mm — for quick-change backing pads on die grinders and small angle grinders
• 100mm and 115mm — for angle grinders
• 125mm and 150mm — for orbital sanders and larger angle grinders
• 180mm — for large-area finishing machines

Match the disc size to the backing pad. Web discs typically use the same TR/TS quick-change mounting as coated abrasive quick-change discs — see our quick change discs range for compatible backing pads.

Operating speed

Web discs run at significantly lower speeds than coated abrasive discs — typically 1000-3000 RPM for general use. Higher speeds melt the synthetic web and damage the disc. Variable-speed grinders are preferred; for fixed-speed equipment, match the equipment's RPM to the disc's rated speed.

Brands stocked at AIMS

Norton, Pferd, and Klingspor cover the web disc range across the standard grades and sizes. Cheap unbranded web discs typically have lower-quality synthetic web that breaks down faster — for sustained finishing work, quality discs deliver better consistency and life.

Working with web discs

Apply moderate pressure — too much pressure compresses the web and reduces effective cutting; too little leaves the disc sliding without cutting. Move the disc continuously across the work; static grinding produces uneven finish. For decorative finishes, work in a single direction (rather than circular motion) to produce parallel scratch patterns characteristic of brushed and satin finishes.
