Product Overview
The flexible abrasive ball hone from LG™ Brush is a cylindrical roller-type flexible honing tool – also sold as a Cylindrical Flex Honing Brush or Roller Flex Hone. Blue nylon flange bases carry dense radial rows of yellow elastic filaments, and every filament tip is fitted with a spherical abrasive ball. The tool mounts on the spindle of a honing machine or CNC machining center and rotates for internal and external bore finishing alike. Unlike a disc-type hone, this industrial ball hone is a cylindrical roller: the filaments cover the entire cylindrical surface, so the working contact area is much larger and a long or deep bore can be honed in one pass. As a flexible honing brush it self-centers against the bore wall, removes burrs and produces a uniform plateau pattern without scratching or gouging the surface.
It is available as a custom flexible abrasive ball hone – a ball hone for large bore plateau finishing as well as a cylinder ball hone for general bore work. Two mounting options are supported: a center wooden core hole for flange clamping, or a metal drive shaft for direct shank mounting.
Specifications and Custom Sizes
Brush diameter and overall length are fully customizable according to customer requirements, from small bores to large-diameter long-bore workpieces.

Custom diameters, lengths, grits and mounting options are produced to order – send us your bore drawing for a tailored proposal.
Material Composition
This flexible abrasive ball hone is built from two material groups:
- Filament: yellow elastic nylon filaments with a spherical abrasive ball bonded to each filament end – flexible, so the ball heads conform to the bore wall instead of cutting into it
- Base / core: blue nylon flange base with a center wooden core hole or metal drive shaft – the blue nylon flange is tough, resists emulsion and lubricating oils without swelling in wet honing, and its low weight keeps spindle load down
Features and Applications
Ball Hone Tool
- Cylindrical roller structure, larger working area – filaments cover the entire barrel surface, so long and deep bores are honed over their full length in one pass; efficiency is higher than a single-disc hone
- Self-adaptive ball tips with elastic filaments – the spherical heads conform to the bore wall, compensating for slight ovality and taper without gouging; cross-hole intersections are deburred while a uniform, controllable plateau pattern is honed at the same time
- Blue nylon flange base, coolant-proof – tough base material stands up to emulsion and lubricating oils in wet honing without swelling or deforming; low self-weight reduces spindle load
- Two mounting options – center wooden core hole with flange clamping, or a metal drive shaft for direct shank mounting (shown in the product photos); both fit CNC machining centers and honing machines
- Grit selection for every target – coarse grits quickly remove machining tool marks and edge burrs; fine grits deliver fine internal polishing and precision plateau patterning for different roughness requirements
- Firmly bonded abrasive balls – the ball heads stay fixed at high spindle speed, wear evenly and keep the finishing result stable over the service life of the honing brush
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 / taper compensation | Yes – flexible filaments | Limited |
| Risk of bore damage | Low – soft cutting action | Moderate to high |
| Cross-hole deburring | Yes – ball tips follow intersections | No |
| Best for | Long, deep and slightly irregular bores | Straight, rigid bore finishing |
Please note: this is a fine-finishing tool. It is not suitable for heavy cutting or large stock removal – use it for precision deburring, honing and surface pattern finishing where bore surface roughness must be controlled.
Ball Hone for Large Bore Plateau Finishing
Typical applications of this cylinder honing brush include:
- Long hydraulic components – deep-bore honing and cross-hole deburring of hydraulic cylinders, pneumatic cylinders and long valve bodies
- Engine components – plateau pattern honing and bore-mouth deburring of cylinder liners, long oil passages and pump housing bores; as plateau honing brushes they prepare oil-retention surfaces in engine cylinders of all sizes
- Marine and large diesel engines – finishing large-diameter cylinder bores in ship propulsion engines, heavy-duty diesel engines, locomotive engines, stationary power units and industrial compressors, where the lightweight core makes large tools practical to handle
- Precision tubes – honing the inner walls of steel and alloy long tubes and removing boring and broaching tool marks
- Construction machinery hydraulics – precision deburring of deep holes and multi-cross-hole intersections in hydraulic valves and hydraulic motors
- Automated CNC honing – mounted on machining centers or dedicated honing machines for high-volume finishing of long-bore workpieces
As a cylinder ball hone and one of the most adaptable honing brushes in this range, the same tool serves engine rebuilders, hydraulic component makers and precision tube manufacturers alike.
Frequently Asked Questions (FAQ)
Q1: Why choose a roller-type flexible abrasive ball hone over a disc-type?
A1: The cylindrical roller carries filaments over its entire barrel surface, so the contact area with
the bore wall is much larger than a single disc. Long and deep bores are honed over their full length
in one pass, which improves efficiency and produces a more uniform finish along the whole bore.
Q2: What sizes are available for this brush?
A2: The brush is customized for diameters ranging from small bores to large-diameter long-bore
workpieces. The lightweight core construction keeps even larger diameters (100mm+) practical to
handle. Contact us with your bore specifications for specific recommendations.
Q3: Which mounting options are supported?
A3: Two options: a center wooden core hole for flange clamping on honing machine spindles, or a metal
drive shaft for direct shank mounting in CNC machining centers. Shaft lengths and mounting
configurations can be engineered to match your bore depths and equipment; custom options are also
available.
Q4: What is the advantage of the wooden center core?
A4: A wooden core significantly reduces overall tool weight compared with steel or plastic cores.
This makes large-diameter brushes easier to handle and maneuver, reduces spindle load and operator
fatigue during extended use, and allows easier access to deep bore applications, while remaining
durable and stable under operating conditions.
Q5: Can this brush be used on out-of-round cylinders?
A5: Yes. The flexible filament design allows the tool to conform to slight bore irregularities,
compensating for ovality and taper. This self-centering, self-compensating action is a key advantage
over rigid honing stones, especially in large-diameter bores where alignment is more challenging.
