Product Overview
The small silicon carbide ball hone from LG™ Brush is a disc-type flexible honing tool built for small precision bore finishing <=43mm. A nylon disc base carries multiple rows of elastic nylon filaments, and every filament tip is fitted with a spherical silicon carbide grit ball. As the tool rotates inside the bore, the flexible ball tips self-center against the bore wall, removing burrs and producing a uniform plateau finish without scratching or gouging the bore surface. Also known as a small SiC ball hone, this custom small silicon carbide ball hone mounts directly on honing machine or CNC machining center spindles through its flange hole. It is an industrial ball hone for small precision bore finishing <=43mm that must hold a consistent, controllable surface finish.
Each disc is built with a cream nylon base, dense rows of black elastic filaments and a spherical silicon carbide head bonded to every tip. Standard discs are marked with grit sizes such as #120 and 240#, and other grits are produced on request.
Specifications and Custom Sizes
Brush diameter and overall length are fully customizable according to customer requirements, so the tool always matches your bore size for proper contact.

Ball Hone Mounts and Shank Options
The disc mounts directly on the flange of honing machines and CNC machining center spindles, which makes it suitable for high-volume automated production. It works in wet or dry machining alike, and a custom spindle interface can be made to match your machine.
Material Composition
This small silicon carbide ball hone is built from two material groups:
- Filament: elastic nylon filaments with a spherical silicon carbide abrasive ball bonded to each filament end
- Base / core: cream nylon disc base with a PP/PVC plastic shaft – lightweight and corrosion-resistant
Features and Applications
Silicon Carbide Grit Ball Hone Specifications
- Self-adaptive ball tips – the spherical silicon carbide heads conform to the bore wall, so they deburr without scratching or gouging the finished surface
- Elastic filament compliance – flexible filaments compensate for bore tolerance and automatically adapt to slightly oval or tapered bores, giving consistent results from part to part
- Full-bore uniform action – rotating ball tips contact the bore wall through 360 degrees, cleaning cross-hole intersections while honing and polishing the bore in one pass
- Grit selection – coarse grits remove burrs and machining tool marks; fine grits produce mirror polishing and fine plateau patterns for different roughness targets
- Flange disc mounting – mounts straight onto honing machine and CNC spindles for high-volume automated production, wet or dry
- Stable service life – abrasive ball heads are firmly bonded, resist coming loose at high speed and wear evenly, keeping the finishing effect stable over time
Unlike rigid honing stones, the flexible filament design self-centers in the bore, compensates for ovality and taper and follows the bore contour without altering critical geometry – while the plateau action removes machining peaks and leaves the valleys intact for oil retention and seal performance.
| Feature | Flexible Ball Hone (this tool) | Rigid Honing Stone |
|---|---|---|
| Self-centering | Yes – automatic | No – requires setup |
| Ovality compensation | Yes – flexible filaments | Limited |
| Plateau finishing | Excellent | Requires special stones |
| Risk of bore damage | Low | Moderate to high |
| Best for | Small precision bores, engine cylinders, hydraulic bores | Large-diameter, straight bores |
Please note: flexible honing brushes are fine-finishing tools. They are not suitable for heavy cutting or large stock removal – use them for precision deburring, honing and surface pattern finishing.
Custom Silicon Carbide Grit Ball Hone Sizes and Grits
Every tool is manufactured to order – brush diameter, overall length, filament density and abrasive grit are all matched to your bore and surface-finish requirement. Typical applications include:
- Engine cylinders and liners – honing cylinder bores to build oil-retention plateau patterns and deburring the cylinder mouth
- Hydraulic valve blocks, cylinders and rams – deburring cross oil-hole intersections and honing bores to improve surface finish and seal life
- Precision machined bore parts – cleaning, honing and removing tool marks in gears, bearing seats and pump bodies
- Automotive components – precision deburring and honing of engine oil passages, gearbox housing bores and brake valve bores
- Precision tubes – polishing the inner walls of steel and alloy tubes and removing mouth-flanging burrs
- 3C and precision hardware – fine finishing of small precision bores where tight surface-roughness control is required

Frequently Asked Questions (FAQ)
Q1: What is a small silicon carbide ball hone used for?
A1: A small silicon carbide ball hone is used for finishing internal bores in engine cylinders,
hydraulic cylinders, pneumatic cylinders and other precision-machined bores. It creates optimized
surface finishes for improved seal performance, oil retention and reduced friction.
Q2: How does the self-centering feature work?
A2: The flexible nylon filaments naturally center the brush within the bore as it rotates. The abrasive
balls on each filament apply uniform pressure against the bore wall, automatically compensating for
slight ovality or misalignment without operator adjustment.
Q3: What is plateau surface finishing?
A3: Plateau finishing removes the microscopic peaks left by previous machining operations while leaving
the valleys intact. This creates a surface with excellent oil retention properties and proper sealing
characteristics, critical for engine cylinders and hydraulic applications.
Q4: Can this ball hone be used on out-of-round cylinders?
A4: Yes. The flexible filament design allows the tool to conform to slight bore irregularities,
compensating for ovality and taper – a key advantage over rigid honing stones, which can cut unevenly in
out-of-round bores.
Q5: How do I select the correct brush diameter for my bore?
A5: The brush diameter should match your bore size for proper contact. For best results, select a
diameter that provides slight interference with the bore surface. Contact us with your bore
specifications for specific recommendations.
