Explore Every 5/8-inch TC Grade with One Compact Assortment
Dedeco Sunburst 5/8″ TC radial bristle discs provide a compact finishing system for cleaning, deburring, blending and polishing small components, detailed contours and restricted surface features.
This loose-disc assortment contains useful quantities across the complete seven-grade range, making it easier to compare cutting actions, develop a finishing sequence and retain the selected grades for further work.
The discs can be used individually for narrow contact or combined in matching stacks to create a broader and more supported working face. Their compact diameter improves visibility and control, while the flexible, curved TC (Type C) bristles provide conformable contact around curves, edges and irregular geometries.
Need to replenish a particular grade? Individual 5/8″ standard-profile TC discs are available separately.

Compare Every Grade
Trial the complete progression from coarse 80 grit through to ultra-fine 1 micron to identify a suitable starting point and finishing sequence.
Compact Access and Control
The smaller 5/8-inch diameter improves visibility and control when finishing small components, detailed contours and restricted features.
Configure the Working Width
Use a single disc for narrow contact or combine matching discs to create a wider and more supported working face for the application.
5/8-inch or 7/8-inch Loose Disc Assortment?
Choose the 5/8-inch assortment for greater visibility, control and access when finishing smaller components and detailed features.
Choose the 7/8-inch assortment for the same seven-grade selection with a larger working diameter suited to broader general cleaning, blending and polishing.
Both assortments contain 12 discs in each grade and include mandrels with 2.35mm and 3.18mm shanks.
Typical Applications
- Comparing abrasive grades and developing repeatable detailed-finishing processes
- Cleaning and refining small cast jewellery and precision components
- Removing oxidation, light contamination and suitable surface coatings
- Controlled deburring around small edges, profiles and machined features
- Blending surface marks and transitions between worked areas
- Finishing detailed contours, internal curves and recessed features
- Refining detailed woodcarvings without obscuring the underlying form
- Progressing from initial cleaning through to fine polishing
Suitable Materials
These discs can be used across suitable precious and non-ferrous metals, steel, stainless steel, cast iron, aluminium, brass and bronze. They are also suitable for selected wood, acrylic, plastic and ceramic applications.
Always test the selected grade on an inconspicuous area first, particularly on softer, coated or heat-sensitive materials.
Assortment Contents & Grades
What's Included
- 84 loose radial discs: 12 discs in each of seven colour-coded grades
- One 2.35mm (3/32″) shank mandrel: For compatible micromotors, flexible shaft handpieces and rotary tools
- One 3.18mm (1/8″) shank mandrel: For tools and collets designed for a true 1/8″ shank

Both screw-top mandrels accept the discs’ 1.6mm (1/16″) centre hole. Select the mandrel whose shank exactly matches your machine, handpiece, chuck or collet.
Grade Selection

Begin with the finest grade capable of producing the required result.
| Colour | Grade | Quantity | Typical Use |
|---|---|---|---|
| Yellow (Coarse) |
80 Grit (Aluminium Oxide) |
12 x loose discs | Heavy cleaning, deburring and initial surface conditioning |
| White (Medium) |
120 Grit (Aluminium Oxide) |
12 x loose discs | Light deburring, smoothing and controlled blending |
| Red (Standard) |
220 Grit (Aluminium Oxide) |
12 x loose discs | Surface blending, scratch refinement and preparation for finer finishing |
| Blue (Fine) |
400 Grit (Aluminium Oxide) |
12 x loose discs | Fine finishing, satin finishing and surface smoothing |
| Pink (Pumice) |
600 Grit (Pumice) |
12 x loose discs | Pre-polishing and preparation for micron finishing |

12 x loose discs | Fine polishing and development of an initial lustre |
| Light Green (Ultra-Fine) |
1 Micron (Aluminium Oxide) |
12 x loose discs | Final high-lustre and highly refined finishing |
Choose the Correct Mandrel
The kit includes two screw-top mandrels for the discs’ 1.6mm centre hole:
- 2.35mm (3/32″) shank for compatible jewellery handpieces, micromotors and flexible shaft systems
- 3.18mm (1/8″) shank for tools and collets designed for a true 1/8″ shank
A 3.18mm shank is not interchangeable with a 3mm collet. Confirm the exact capacity of the tool before fitting the mandrel.
Adjust the Working Width
Use one loose disc for the narrowest contact or combine matching discs to increase the working width and provide a more supported finishing action.
- Only stack discs of the same diameter, profile and grade
- Align every disc in the same direction of rotation
- Ensure the mandrel screw remains fully and securely engaged
- Do not mix different grades within the same working stack
Operating & Safety Guidance
- Recommended operating range: 3,000–18,000 RPM
- Woodworking reference speed: Approximately 5,000 RPM
- Never exceed the lowest maximum speed stated for the disc, mandrel or machine
- Confirm that the selected mandrel shank exactly matches the machine, chuck or collet
- Install every disc so the tail of each curved bristle follows the direction of rotation
- Use the bristle tips with light pressure rather than forcing the discs into the workpiece
- Keep the tool moving to control localised heat and uneven wear
- Check that the screw-top mandrel is secure before starting the machine
- Use suitable machine guarding and appropriate personal protective equipment
