SiC Ball Hone™

ESS SiC Ball Hone™

Internal Bore Deburring & Finishing

ESS SiC Ball Hone™ tools are flexible, spherical-tip abrasive brushes designed to finish and deburr the inside of bores, tubes, ports, and cross-holes. Silicon-carbide–impregnated filaments conform to minor bore irregularities to produce a controlled plateau finish without altering size.

Highlights

Conforming “ball” tips blend edges at intersections and cross-holes
SiC abrasive cuts efficiently on cast iron, steel, stainless, aluminum
Produces a uniform plateau finish that improves lubrication and wear-in
Prevents sharp edges and micro-burrs; protects dimensional accuracy
Runs in CNCs, drill presses, hand tools, or robotic cells with coolant.

Use & Setup

Select a hone slightly larger than bore ID for proper contact
Use low–medium RPM with light stroke; keep tool and bore lubricated
Short, even reciprocation; avoid dwelling in one location
Ideal for hydraulic/pneumatic passages, engine components, valve bodies, medical and aerospace fittings

Customization available: grits #80 – #800, brush diameters 3–300 mm, lengths 20–1500 mm. Non-standard sizes: 50-piece minimum.

Features & Applications

Silicon Carbide Abrasive Filaments
Provides aggressive cutting action for efficient deburring, surface refinement, and edge radiusing.
Spherical Abrasive Structure
Flexible abrasive balls mounted at the filament tips conform to bore geometry and surface irregularities.
Non-Loading, Self-Renewing Action
Abrasive media wears evenly, exposing fresh cutting edges throughout the tool’s life.
Controlled Surface Finishing
Produces a plateaued, cross-hatched surface ideal for lubrication retention and reduced friction.
Maintains Dimensional Integrity
Removes peaks but does not alter bore size, roundness, or geometry.
Compatible With a Range of Materials
Works on steel, cast iron, aluminum, stainless, and certain hard coatings.
