Product Overview

Our ceramic fiber radial disc brush is manufactured from ceramic fiber (red/teal) and engineered for cross-hole radial deburring, with key advantages including star-shaped radial filament structure, ceramic fiber material properties and self-sharpening performance.

Also known as custom ceramic fiber radial disc brush, industrial disc brush or disc brush for cross-hole radial deburring.

Specifications and Custom Sizes

Custom Ceramic Fiber Disc Brush Sizes and Grits

Customizable according to customer requirements – brush diameter, filament length, shank diameter, and overall length fully tailored to match specific hole sizes and workpiece geometries. Standard shank diameters available for direct mounting in CNC machining centers, electric spindles, and power tools.

Material Composition

This brush is built from 2 material groups – the ceramic fiber and steel straight shank:

  • Filament Material:   Ceramic fiber – flexible, resilient ceramic fiber filaments with self-sharpening properties. Each filament consists of approximately 1,000 micro-ceramic fibers that act as sharp cutting edges . Unlike ceramic abrasive (grit-embedded) brushes, ceramic fiber brushes grind exclusively with the tips of the fibers, enabling much higher precision, faster material removal, and the ability to work on materials up to 65 HRC .
  • Shank / Base Material:   Steel straight shank with integrally pressed ceramic fiber filaments – radial star-shaped filament arrangement with multiple filament groups radiating outward from the shank base. Standard cylindrical shank for direct collet mounting in CNC spindles, robotic arms, and handheld tools.

Features and Applications

Ceramic Fiber Disc Brush

Our   Star-Shaped Mounted Ceramic Fiber Brush   features a unique radial star-shaped filament arrangement where multiple ceramic fiber bundles radiate outward from the steel shank base in a star configuration. This design – also known as a star-type ceramic fiber brush, cross-hole ceramic deburring brush, or radial fan-blade mounted brush – provides 360° multi-directional deburring action that reaches internal hole walls, cross-hole intersections, and bore edges that standard end-face brushes cannot access .

Core Advantages:

  • Star-Shaped Radial Filament Structure   – filaments radiate outward in multiple directions, conforming to internal hole walls, cross-hole intersections, and small bore interiors. Effectively reaches hole walls and bore edge intersections that standard end-face brushes cannot access .
  • Ceramic Fiber Material Properties   – flexible yet resilient fibers provide gentle cutting action that will not scratch or gouge workpiece base materials. Produces no metallic residue and will not cause iron contamination on non-ferrous metals. Heat-resistant for both wet and dry processing environments .
  • Self-Sharpening Performance   – ceramic fibers continuously expose fresh cutting edges during operation, maintaining consistent grinding power throughout the brush's entire service life with no deformation .
  • One-Piece Shank-Mounted Design   – standard cylindrical shank allows direct collet mounting in CNC machining centers, electric spindles, and power tools. Simple mounting with high concentricity, suitable for high-speed automated rotary operations.
  • Flexible Buffering Action   – filaments provide elastic compliance, self-adapting to workpiece dimensional variations without gouging hole walls. Uniformly removes hole entry burrs and rolled edges.
  • Multi-Directional Deburring   – during rotation, filaments act 360° on the workpiece, simultaneously cleaning hole entry faces and internal bore walls. Particularly effective for deburring cross-hole intersection edges.

  • Automotive Parts   – engine oil passage holes, transmission valve bodies, and injector housing cross-hole deburring
  • 3C Precision Hardware   – precision micro-hole and vent hole entry burr removal, protecting finished workpiece surfaces from scratching
  • CNC Automated Finishing   – direct spindle mounting on machining centers for high-volume post-machining deburring operations
  • Mold Components and Precision Tube Fittings   – tube end finishing and small bore internal wall cleaning, removing machining flash

Frequently Asked Questions (FAQ)

Q1: What is the difference between ceramic fiber brushes and ceramic abrasive (grit) filament brushes?
Ceramic fiber brushes use thousands of micro-ceramic fibers as cutting edges – each filament consists of approximately 1,000 individual fibers that act as cutting tools . They provide consistent grinding power throughout the brush's life with no deformation. Ceramic abrasive (grit) filament brushes rely on embedded abrasive particles that wear and lose effectiveness over time. Ceramic fiber brushes are the world's first practical application of this technology for CNC deburring .

Q2: What is the advantage of the star-shaped radial filament arrangement?
The star-shaped radial arrangement allows filaments to reach internal hole walls, cross-hole intersections, and bore edges that standard end-face brushes cannot access. During rotation, filaments act 360° on the workpiece, simultaneously cleaning hole entry faces and internal bore walls – particularly effective for cross-hole intersection deburring.

Q3: Can this brush be used on aluminum, copper, or other non-ferrous metals?
Yes. Ceramic fiber brushes produce no metallic residue and will not cause iron contamination on non-ferrous metals. The flexible fibers provide gentle cutting action that will not scratch or gouge soft materials, making them ideal for aluminum, copper, brass, and other non-ferrous alloys.

Q4: Is this brush suitable for automated CNC and robotic applications?
Yes. The standard cylindrical shank allows direct collet mounting in CNC machining centers, electric spindles, and robotic arms . The brush can be used in the same tool changer as cutting tools, enabling deburring and finishing immediately after machining . The consistent performance and no-deformation characteristics make it ideal for high-volume automated production.

Q5: What is the recommended operating speed and technique?
Recommended speed depends on brush diameter and application. Typical speeds range from 1,500–3,000 min⁻¹ for most applications. When deburring cross-holes, the brush should be rotated while being inserted and withdrawn – the ceramic fibers will self-adapt to the hole geometry. Always start at lower speeds and increase gradually. Coolants and lubricants are recommended for extended service life.
