Alloy grinding head set diamond grinding head set with elliptical cone shape, 80 mesh emery material, 3mm shank diameter, 45mm length for detailed work on glass, jade, and stone surfaces in diamond or golden diamond colour options.
Alloy Grinding Head Set with 80 Mesh Emery for Detailed Glass, Jade, and Stone Work

This alloy grinding head set is designed for precise material removal and surface finishing on hard, brittle materials commonly used in hobbies, repairs, and small-scale crafting. The key feature is its elliptical cone head shape, which offers a specific contact point for controlled grinding rather than broad, flat abrasion. Paired with an 80 mesh emery grit, it is suited to finer finishing tasks on surfaces like glass, jade, and various stones, allowing users to shape, smooth, or detail these materials without the aggressive cutting of coarser abrasives. Its 3mm shank ensures compatibility with a wide range of standard rotary tools, making it a practical accessory for detailed workshop projects.
Features and Construction

The set's design focuses on providing a specialised tool for detailed abrasive work, with construction details centred on fit, form, and application scope.
Material and Build
The grinding heads utilise an alloy construction, which houses and supports the emery abrasive material. Emery, a natural abrasive grain, is presented here in an 80 mesh size, indicating a moderately fine grit suitable for finishing rather than rapid stock removal. This material choice is directed towards work on glass, jade, and stone, where controlled abrasion is needed to avoid cracking or chipping the workpiece. The build is centred on integrating this abrasive effectively into a durable, rotary-tool-compatible head.
Size and Practical Fit
Each head has a 3mm outside diameter and an identical 3mm shank diameter, ensuring a uniform profile that fits standard 3mm collets in most rotary tools. The 45mm overall length provides sufficient extension from the tool collet to reach into details or work on contoured surfaces. The elliptical cone shape of the grinding head itself dictates how it contacts the material, allowing for work in corners or on curved edges where a flat or spherical head might not be as effective.
Uses and Placement

This product is defined by its stated application on specific materials, guiding its placement in workshop scenarios and hobbyist toolkits.
Event or Professional Use
In professional or semi-professional contexts, such as jewellery making, stone carving, or glass art, these heads can be used for final detailing, smoothing seams, or refining shapes on jade, glass inlays, or small stone pieces. The 80 mesh grit is appropriate for moving from a rough shape to a finer finish, preparing a surface for polishing. The precise head shape allows for working in tight areas on intricate designs where control over material removal is critical.
Everyday Home Use
For DIY enthusiasts or hobbyists, this set addresses tasks like smoothing the edges of a cut glass tile, shaping a piece of jade for a personal project, or refining a stone collected for display. Its compatibility with common rotary tools makes it accessible for home workshops. The specification for glass, jade, and stone provides clear guidance on what materials it is intended for, helping users select the right accessory for repairing a glass ornament, modifying a stone specimen, or crafting with jade beads.
Benefits and Buying Value

The value of this grinding head set lies in its specific design for detailed work on particular materials, offering a focused tool rather than a general-purpose abrasive.
Reuse and Low Maintenance
As a solid abrasive head, it is designed for repeated use until the emery material wears down. There are no moving parts or complex components to maintain. Users simply attach it to their rotary tool and proceed with their work. The alloy body helps retain the abrasive grit during use. For the stated materials, it provides a dedicated solution that can be reached for whenever a fine finishing task on glass, jade, or stone arises, potentially reducing the need for multiple less-suitable tools.
Why Choose This Product
This set is chosen for its combination of a specific elliptical cone shape, a defined 80 mesh abrasive grit, and clear application guidelines. If your work involves detailed finishing on glass, jade, or stone, the product's specifications directly match that need. The 3mm shank ensures wide tool compatibility, and the provided dimensions give a clear expectation of its size. It offers a concrete, specification-led option for users who require more control and finesse than a standard coarse grinding bit provides.
