Smooth and refine curved, recessed, and hard-to-reach surfaces with the Covington Resin Diamond Smoothing Cone.

The Covington Resin Diamond Smoothing Cone is a specialty diamond grinding accessory designed to expand the capabilities of your Covington Flat Lap. Made with a resin-bond diamond abrasive, the cone provides a smooth, controlled grinding action that is ideal for refining curved and recessed surfaces that are difficult to reach with a conventional flat lap disc.

Used with the Covington Male-to-Male Brass Adapter, the Smoothing Cone mounts directly to the center shaft of your compatible Covington Flat Lap. This gives you a convenient way to work on the inside of curves, bottle openings, bowls, and other uniquely shaped pieces.

Resin-Bond Diamond for Smooth, Controlled Grinding

Unlike loose abrasive or conventional grinding surfaces, a resin-bond diamond tool holds diamond abrasive within a resin matrix to provide a consistent working surface.

The result is a controlled grinding action that makes the Smoothing Cone especially useful for smoothing, refining, and shaping curved surfaces where precision and control are important.

The resin-bond construction is well suited for finishing work where you want to progressively refine a surface rather than aggressively remove large amounts of material.

Reach Areas a Flat Lap Disc Can't

A standard flat lap disc is designed primarily for flat surfaces. The Smoothing Cone gives you a shaped working surface that can reach into areas where a flat disc simply cannot.

Use it for:

  • Inside curves and concave surfaces
  • Bottle openings and necks
  • Bowls and rounded objects
  • Recessed areas
  • Irregular and sculptural pieces
  • Detail grinding and smoothing
  • Lapidary and glass projects requiring a curved working surface

Designed for Covington Flat Laps

The Smoothing Cone is designed to be used with the Covington Flat Lap Male-to-Male Brass Adapter. The adapter provides the threaded connection needed to mount the cone to the center shaft of your compatible Covington Flat Lap.

Once installed, the cone rotates with the machine, allowing you to bring your workpiece into contact with the resin-bond diamond surface.

A Versatile Addition to Your Lapidary Setup

The Resin Diamond Smoothing Cone gives you another option when your project involves curves, openings, or recessed surfaces.

Instead of trying to maneuver a flat disc into an area it wasn't designed to reach, the cone provides a more natural working surface for curved and detailed areas. This makes it a valuable accessory for lapidary artists and glassworkers who work with more than simple flat slabs.

How to Use the Smoothing Cone

  1. Remove the brass centering pin from the center of your compatible Covington Flat Lap.
  2. Install the Covington Male-to-Male Brass Adapter.
  3. Thread the Resin Diamond Smoothing Cone onto the adapter.
  4. Bring your workpiece into gentle contact with the cone and begin smoothing.

Use appropriate water and lubrication for your specific material and application, and avoid excessive pressure that can unnecessarily wear the diamond abrasive.
