These polishing wheels feature a standard 2.35mm shank, making them compatible with most rotary tools, engravers, dental drills, and hobby grinders. Popular compatible tools include Dremel rotary tools, Proxxon engravers, and similar precision tools with collet systems that accept 2.35mm shanks.

Absol�utely! While specifically designed for delicate materials like jade, amber, and beeswax, these polishing wheels work excellently on various materials including precious stones, polished metals, plastics, bone, ivory, and wood. The fine diamond powder coating provides exceptional results on any material that requires a smooth, polished finish.

Select the grit based on your polishing stage: Gray (coarse) for initial polishing on smooth surfaces, Pink (medium) for intermediate smoothing and scratch removal, and Blue (fine) for final polishing and achieving mirror finishes. For best results, progress through the grits sequentially rather than skipping directly to fine polishing.

The bullet shape offers superior access to detailed areas, corners, and intricate designs that flat polishing wheels can't effectively reach. The pointed tip allows for precision work in tight spaces, while the rounded body provides broader surface coverage when needed. This versatility makes them ideal for complex jewelry pieces, carved designs, and detailed artwork.

The lifespan depends on usage intensity and materials being polished. With normal use on appropriate materials (already smooth surfaces), these wheels can last through multiple projects. The diamond powder coating is durable, and the rubber base maintains its shape well. Avoid excessive pressure and high speeds to maximize their lifespan.
