Blending & Unitised Discs – Controlled Finishing & Surface Refinement
Browse our range of high-performance blending and unitised discs — engineered for weld blending, surface conditioning, deburring and controlled finishing. Designed for use on angle grinders and compatible tools, these discs help refine surfaces without deep scratch patterns, making them ideal for metal fabrication, stainless finishing and decorative work.
Blending & Unitised Discs – Choose the Right Type for Your Task
Blending and unitised abrasives are designed to bridge the gap between aggressive grinding and fine finishing. Unlike traditional grinding discs, these products provide a more controlled cut, helping to remove surface defects, feather welds and refine finishes while maintaining surface integrity. Selecting the correct disc type — felt, spectrum wheels, stripping or unitised — ensures the right balance of cut rate, conformity and finish quality.

Felt Discs
Felt discs are designed for polishing, buffing and final finishing. When paired with polishing compounds, they deliver a refined, high-quality surface finish on stainless steel and decorative metals.
Popular choices include Turbo Felt Discs for precision polishing and finishing applications.
- Best for: polishing, fine finishing, compound application
- Why choose: smooth finish with minimal surface marking
- Tip: use with appropriate polishing compounds for best results
Spectrum Wheels
Spectrum wheels provide a balanced blend of cut and finish, making them ideal for weld blending and surface refinement where you need controlled material removal without aggressive gouging.
Designed for consistent performance across mild and stainless steel surfaces.
- Best for: weld blending, surface refinement
- Why choose: consistent cut with controlled finish
- Tip: ideal after initial grinding to refine weld seams
Stripping Discs
Stripping discs are built for coating removal, rust removal and surface cleaning. Their open structure helps prevent clogging while efficiently removing paint, sealants and oxidation.
Excellent for preparation work prior to refinishing or recoating.
- Best for: paint removal, rust removal, cleaning
- Why choose: aggressive cleaning without heavy material removal
- Tip: apply moderate pressure to maximise disc life
Unitised Discs
Unitised discs are manufactured with compressed non-woven abrasive layers to provide precise deburring, edge blending and controlled finishing. They offer excellent durability and maintain consistent performance throughout their life.
Suitable for stainless steel, mild steel and non-ferrous metals where consistent results are essential.
- Best for: deburring, edge refinement, weld blending
- Why choose: durable construction with predictable finish
- Tip: choose grade carefully depending on required aggressiveness

Frequently Asked Questions
What are blending and unitised discs used for?
They are used for weld blending, deburring, polishing, coating removal and controlled surface refinement without deep scratch marks.
What’s the difference between stripping and unitised discs?
Stripping discs focus on removing coatings and contamination, while unitised discs are designed for more precise deburring and controlled finishing.
Can I use these on stainless steel?
Yes — they are commonly used on stainless steel for weld blending, finishing and decorative surface refinement.
When should I choose felt discs?
Use felt discs when polishing or buffing with compound to achieve a refined, high-gloss finish.
