Complete 3-inch TC 6-Ply Radial Wheel Assortment
The Dedeco Sunburst 3″ TC 6-ply radial disc assortment contains eight pre-assembled wheels, providing a complete colour-coded grade progression from aggressive surface preparation through to fine polishing.
Each wheel combines six matching radial disc layers into a 1/4″ (6.35mm) working face. This wider, supported format provides stable surface contact and efficient coverage across broader surfaces, larger components and repeat production work.
Flexible, curved TC bristles follow contours, edges and irregular surfaces while helping to preserve the underlying component shape. Aluminium oxide abrasive is distributed throughout the moulded polymer bristles, maintaining the cutting action as they wear without requiring a separate polishing compound.
Already know the grade you need?
Individual 3″ TC grades are available as loose discs for configurable working widths or as ready-assembled 6-ply wheels matching the format supplied in this kit.
Why Choose This 6-Ply Assortment?
Complete Eight-Grade Range
Work through every aluminium oxide grade from ultra-coarse 36 grit to ultra-fine 1 micron for cleaning, deburring, surface preparation and polishing.
Ready-Assembled 6-Ply Wheels
Every grade is supplied as a complete six-layer assembly with a consistent working width, eliminating the need to build individual disc stacks.
Efficient Surface Coverage
The 3″ diameter and 1/4″ working face provide stable contact and efficient coverage across broader surfaces and larger components.
Choose the Right 3-inch Radial Disc Format
Choose the 6-ply assortment for a wider 1/4″ working face with increased support, surface contact and coverage across broader areas.
Choose the 3-ply assortment for an approximately 1/8″ working face that provides narrower, more controlled contact around contours, edges and smaller features.
Choose individual 3″ TC grades when you already know the required grade. Loose discs allow you to configure the working width, while pre-assembled 6-ply wheels provide direct replacements in the same format as this assortment.
Typical Applications
- Comparing all eight grades in a consistent 1/4″ 6-ply working format
- Developing repeatable multi-stage cleaning, deburring and finishing sequences
- Finishing broader surfaces and larger components with stable, supported contact
- Reducing assembly and reconfiguration time during repeated grade changes
- Removing rust, oxidation, tarnish and surface contamination
- Cleaning suitable coatings, adhesive residue and discolouration
- Deburring and blending larger edges, profiles and machined features
- Blending scratches, machining marks and surface transitions
- Refining cast, fabricated and machined components
- Generating or refining consistent decorative grain patterns
- Progressing from initial surface preparation through to fine polishing
Suitable Materials
These wheels are suitable for finishing aluminium, brass, bronze, carbon steel, cast iron, stainless steel, precious metals and other appropriate metals. They may also be used for selected wood, acrylic and plastic applications.
Always test the selected grade on an inconspicuous area first, particularly on softer, coated or heat-sensitive materials.

Recommended Tapered Mandrels
All four Moleroda tapered mandrels with a 6mm shank can safely be used with these 3″ radial wheel assemblies.
- MM17 and MM32: Moleroda’s primary tapered-mandrel recommendations for 3″ radial wheel assemblies
- PB39: Regular tapered mandrel that is also compatible with the 3″ assemblies
- PB38: Extended tapered mandrel for applications requiring additional reach
- All four options have a 6mm shank for a compatible chuck or collet
- Wind the wheel fully and securely onto the taper before starting the machine
Bench-Lathe Use
The 3″ wheels are suitable for variable-speed polishing lathes such as the Foredom M.BL. The M.BL operates from 500–7,000 RPM, so use these wheels within the overlapping 3,000–7,000 RPM range.
- Use the appropriate tapered spindle or compatible chuck-mounted taper
- Confirm the correct spindle hand and direction of rotation
- Ensure the wheel tightens onto the taper during operation
- Operate within the overlapping speed range of the wheel and machine
- Use suitable guarding and extraction for the application
Operating & Safety Guidance
- Recommended operating range: 3,000–18,000 RPM
- Woodworking reference speed: Approximately 5,000 RPM
- Maximum wheel speed: 25,000 RPM
- Never exceed the lowest maximum speed specified for the wheel, mandrel, spindle or machine
- Confirm that the wheel is fully wound onto the taper and runs true before use
- Install the wheel so the curved bristles follow the correct direction of rotation
- Start at a lower speed and increase only where greater cutting action is required
- Use the bristle tips with light pressure rather than forcing the wheel into the workpiece
- Keep the wheel moving to control localised heat and uneven wear
- Inspect the wheel and mounting system before every use
- Use suitable machine guarding, extraction and appropriate personal protective equipment
