5/8″ (16mm) Dedeco Sunburst TC Radial Bristle Discs – Precision Standard
£1.60
Precision finishing where access and control are critical.
Best for: Intricate detail work, tight access, jewellery settings and precision finishing
Control: Smaller 16mm diameter improves visibility and handling
Setup: Stack 3 – 6 discs on an MM503 mandrel for best performance
The Dedeco Sunburst 5/8″ TC radial bristle disc is the smallest standard screw-mounted radial disc in the Dedeco Sunburst range, designed for detailed finishing where larger discs may be too broad or difficult to control.
Ideal for complex geometries and confined areas, these discs allow you to clean, deburr and polish tight features without compromising surrounding detail.
Diameter: 5/8″ (16mm)
Arbor Hole: 1.6mm
Recommended Mandrel: MM503 Screw-Top Mandrel (2.35mm or 3mm shank options)
Format: Standard TC (curved bristles)
Grit Range: 80 grit to 1 micron
Key Benefits
- Excellent access to tight spaces, internal curves and recessed features
- Maintains sharp edges and fine surface detail
- Controlled finishing action for delicate or detailed work
Mounting note:
These discs have a 1.6mm centre hole and are designed for use with the MM503 screw-top mandrel.
For best performance, stack multiple discs together rather than using a single disc.

Precision Finishing with 5/8 inch Sunburst Discs
The Dedeco Sunburst 5/8″ radial disc is the precision-detail option within the screw-mounted Dedeco range. Its smaller diameter makes it ideal for controlled finishing in areas where 7/8″ or 1″ discs may feel too large or aggressive.
It is especially useful for jewellery, watchmaking, dental, restoration and micro-engineering work where access, visibility and surface control are critical.
Increased Access
The compact 16mm diameter reaches into tighter areas than larger radial discs, including grooves, undercuts and recessed features.
Improved Visibility
The smaller working profile gives the user a clearer view of the workpiece during detailed finishing.
Greater Control
Ideal for cleaning, blending and polishing without flattening detail or removing unnecessary base material.
Typical Applications
Jewellery & Watchmaking
- Polishing inside ring settings and galleries
- Cleaning undercuts and detailed features
- Finishing prongs, claws and intricate components
Micro-Engineering
- Deburring small machined parts
- Cleaning threads, holes and internal features
- Surface refinement on miniature components
Dental Laboratory
- Finishing small prosthetics and detailed structures
- Cleaning confined shapes and fine geometries
Restoration & Decorative Work
- Cleaning engravings and textured surfaces
- Preserving fine detail without over-cutting
- Refining small cast or decorative metalwork

Mounting & Compatibility
These discs have a 1.6mm centre hole and should be used with the MM503 screw-top mandrel.
- Recommended mandrel: MM503 screw-top mandrel
- Compatible shanks: 2.35mm or 3mm, depending on your tool
- Recommended setup: Stack multiple discs for best performance
- Typical stack: 3 – 6 discs
Important: Do not use with MM304 mandrels. The 3mm screw is too large for these 5/8″ discs.
Compare Small Dedeco Detail Discs
| Format | Best for |
|---|---|
| 5/8″ standard discs | Stackable precision finishing with good stability and control |
| 1/2″ Snap-On discs | Quick-change detail work and fast grade progression |
| 7/8″ standard discs | General cleaning, blending and polishing with more surface coverage |
| 7/8″ knife-edge discs | Grooves, prongs and narrow recessed areas |
Choose 5/8″ discs when you want a small, stable, stackable screw-mounted setup.
Choose 1/2″ Snap-On discs when fast grade changes are more important than custom stack width.
Operating Guidelines
Recommended speed:
3,000 – 18,000 RPM (5,000 RPM for woodworking)
Stacking:
For best results, stack 3 – 6 discs on an MM503 mandrel to create a flexible, cushioned abrasive head.
Orientation:
Ensure the bristle curvature follows the direction of rotation.
Technique:
Use light pressure and allow the bristles to conform to the surface. Excessive pressure can reduce disc life and produce less consistent results.
Complete Your Finishing Process
The Right Mounting
These 5/8″ discs require an MM503 screw-top mandrel. Choose the 2.35mm shank for micromotors and jewellery handpieces, or the 3mm shank for compatible rotary tools and flexible shaft systems.
Need More Surface Coverage?
Move up to 7/8″ Dedeco Sunburst TC radial discs for the standard all-rounder size.
Working in Even Tighter Spaces?
Use 1/2″ Dedeco Snap-On discs for ultra-small access and faster grade changes.
Need Narrow Groove Access?
Use 7/8″ Dedeco Knife-Edge discs for prongs, channels and recessed detail work.
