ESS Stoned™

Precision Mounted Abrasive Stones for Drilled Hole Deburring & Edge Cleanup

The ESS Stoned™ series is built around a ceramic-fiber oil-stone / mounted abrasive point structure designed for high-precision internal hole and port deburring, chamfering, and edge blending applications. According to the original manufacturer’s description, the tool uses “developed ceramic fiber oil stone” technology suitable for removing burrs from edges of holes and cross-holes with minimal impact on part geometry.

Typical Performance Metrics

Example: 6 mm brush at ~5,000 rpm achieved clean finish in ~3 seconds in stainless steel.
Burr root size target: below ~0.1 mm for optimum performance.

How to Use & Processing Tips

Secure the tool handle in a machine spindle, collet or appropriate holder.
Set appropriate speed and feed (manufacturer example: ~5,000 to 7,000 rpm for certain diameters) and program a light radial contact, reciprocating or helical motion as needed.
For cross-hole cleanup: engage and walk the tool across the intersection to remove burr root; avoid dwelling at one spot.
Provide coolant or lubrication if required; maintain stable contact without excessive pressure to minimize tool wear and avoid part damage.
Observe maximum speed and tool usage guidelines. The source warns that “breakage occurs when used beyond the maximum rotational speed or used with a pneumatic tool.”

Grit & Material Designation

#800 (Blue): For softer metals (aluminum alloy, copper, brass).
#400 (Orange): For moderate-hardness metals.
#180 (Yellow): For harder metals (stainless steel, iron, die-castings).

With ESS Stoned™, you get a robust, high-precision internal-hole deburring/finishing tool capable of handling cross holes and tight geometries while maintaining surface integrity and dimensional control. It’s ideal for high-volume automated cells, precision components, and materials ranging from aluminum to stainless.

Features & Applications

Super-effective, consistent precision grinding force: The fiber oil-stone comprises countless micro-cutting edges at each individual fiber tip. The result: rapid burr removal and very stable cutting performance with continual self-sharpening.
No damage during deburring and polishing: Because the material is constructed from ceramic fiber rather than loose abrasive grains, the tool avoids scratching, gouging or deforming sensitive internal surfaces. The original text highlights “the impact on the metal inner hole’s side is almost negligible… leaving no scratches on the surface.”
Durable and shape-stable: The ceramic-fiber oil stone is more durable than conventional abrasive nylon brushes, offering longer service life and higher productivity.
Flexible-shaft version available: The flexible shank or shaft allows the tool to enter narrow workpieces, adapt to cross holes, blind holes and interior contours.
