Product Overview
The silicon carbide ball-tip brush from LG™ Brush is a plate-type flexible honing tool – also sold as a Plate Type Flexible Honing Brush or Matrix Ball-tip Honing Brush. A square composite base – a wooden core block with a perforated metal face plate – carries a dense matrix of independent elastic stems, and every stem tip is fitted with a spherical silicon carbide ball. Mounting holes are pre-drilled in the base, so the plate bolts straight onto machine tables, reciprocating honing equipment or robotic end-effectors. Unlike rotating bore hones, this is a planar matrix brush: it is built for flat surfaces, cavities and stepped faces, deburring and honing them with a soft, self-following touch. As an industrial ball-tip brush it covers wide areas in one pass while each independent stem floats over bumps and valleys without gouging the workpiece.
It is available as a custom silicon carbide ball-tip brush – stem density, stem height, base dimensions and abrasive grit are all produced to order for your fixture and workpiece.
Specifications and Custom Sizes
Brush dimensions and stem specifications are fully customizable according to customer requirements, so the plate always matches your fixture and working area.

Custom Silicon Carbide Grit Ball-tip Brush Sizes and Grits
Every plate is manufactured to order. Typical configurations combine a coarse grit for breaking edges and removing machining marks with a fine grit for final honing and polishing – tell us the surface roughness you need and we will match the grit sequence.
Material Composition
This silicon carbide ball-tip brush is built from two material groups:
- Stems and ball tips: independent elastic stems, each carrying a spherical silicon carbide abrasive ball bonded at its tip – high hardness with a soft, rounded cutting action on ferrous metals, cast iron and hard alloys
- Base: wooden core block with a perforated metal face plate – the wood keeps the plate light and damps vibration, the metal plate grips each stem firmly and carries the pre-drilled mounting holes for fixture bolts
Features and Applications
Silicon Carbide Grit Ball-tip Brush
- Matrix of independent elastic stems – every ball-tip stem floats on its own, adapting to recessed cavities, irregular planes and stepped faces; the stems follow the highs and lows of the workpiece instead of digging into it, so every zone gets even contact
- Soft spherical cutting action – the ball heads remove burrs and tool marks gently, generating a uniform, controllable surface pattern without over-cutting or scratching
- Square base, flexible fixture compatibility – pre-drilled mounting holes let the plate be bolted onto honing machines, gantry equipment, machine tables or robotic polishing tooling; it works in reciprocating and planar motion rather than being limited to a rotating spindle
- Custom layout and grit – stem density, stem height and abrasive grit are tailored to the job: coarse grits strip flash and tool marks, fine grits deliver fine honing and polishing
- Long, stable service life – the abrasive balls are firmly bonded, and a single damaged stem does not affect the rest of the plate, making it suitable for long automated production runs
Unlike a standard flat brush, the ball-end tips distribute pressure evenly across the whole working face: the scratch pattern stays uniform and the risk of gouging stays low. And unlike rotating bore hones, this plate is a planar tool – it finishes flat surfaces, cavities and steps rather than internal bores.
| Feature | Ball-tip Plate Brush (this tool) | Standard Flat Brush |
|---|---|---|
| Stem tip shape | Rounded spherical ball-end | Flat or pointed |
| Surface contact | Smooth, self-following per stem | Variable |
| Scratch pattern | Uniform, controlled | May be uneven |
| Risk of gouging | Low | Moderate |
| Irregular / stepped faces | Yes – independent stems float | Limited |
| Best for | Finishing, conditioning, cavities | Aggressive cleaning |
Please note: this plate brush is a fine-finishing tool for planar, cavity and stepped-face work. It is not a rotating internal-bore tool and is not suitable for heavy cutting or large stock removal – use it for precision deburring, honing and surface texturing.
Ball-tip Brush for Wide-area Vibratory Finishing
Typical applications of this industrial ball-tip brush include:
- Mold and die cavities – deburring and surface honing of concave and convex mold cavities, parting faces and stepped faces of die-casting and injection molds, including the removal of EDM recast textures
- Large valve and pump bodies – burr cleanup and surface refinement on valve end faces, internal cavity steps and multi-cavity parts
- Sheet metal, castings and irregular planes – removing gate burrs and casting marks from aluminum and cast-iron castings, along edges and slots of irregular faces
- Gantry honing and robotic deburring – bolted to the machine table or robot end-effector for high-volume finishing of wide panels and complex cavities; the same ball-tip brush for wide-area vibratory finishing setups keeps the finish consistent across the whole plate
- Hydraulic component cavities – cross-edge deburring of valve-block internal cavities and stepped grooves to improve the surface texture
As a custom silicon carbide ball-tip brush it can also be laid out for general flat work – plates, panels and SiC ball-tip brush finishing of large planar surfaces – with the stem matrix matched to your workpiece.
Frequently Asked Questions (FAQ)
Q1: What is the advantage of the matrix ball-tip design?
A1: Each stem in the matrix is an independent, floating unit topped with a spherical silicon carbide
ball. The rounded tips distribute pressure evenly, so the plate removes burrs and machining marks
with a low risk of gouging, while the independent stems follow recesses, steps and irregular faces
that a rigid brush would miss.
Q2: What materials can this brush effectively process?
A2: The SiC abrasive is highly effective on ferrous metals including carbon steel, cast iron, alloy
steels and hard alloys – typical in mold, die, valve and pump applications. It is equally suitable
for aluminum castings and other non-ferrous parts where burr removal and surface refinement are
needed.
Q3: How is the plate mounted on my equipment?
A3: The wooden and metal composite base has pre-drilled mounting holes, so the plate bolts directly
onto honing machines, gantry equipment, machine tables or robotic end-effectors. It is designed for
reciprocating and planar motion – no rotating spindle required. Base dimensions and hole patterns
are customized to your fixture.
Q4: What is the difference between this plate brush and a rotating bore hone?
A4: This is a planar matrix tool: it is fixed to the machine or robot and finishes flat surfaces,
cavities and stepped faces with reciprocating movement. Rotating ball hones, by contrast, spin on a
spindle to finish internal bores. If your work is internal-bore honing, choose a disc or roller type;
for flat, cavity and stepped-face finishing, this plate is the right shape.
Q5: How do I determine the correct plate size and grit for my application?
A5: Plate dimensions should cover your working area, and stem density, height and grit follow the
finish you need – coarse for burr and tool-mark removal, fine for fine honing and polishing. Contact
us with your workpiece specifications and surface-roughness target for specific recommendations.
