Foredom 2'' Ao Unmtd Wheel 3/8 Arbor 400 Grit

Description:

2" Aluminum Oxide Unmounted Wheel with a 3/8" arbor and 400-grit abrasive surface is designed for fine finishing, smoothing, and pre-polishing of dental laboratory materials. With its ultra-fine abrasive texture, this wheel is widely used in the later stages of appliance fabrication, where achieving a refined, even surface is essential before final polishing. Dental technicians rely on the 400-grit wheel when working on acrylic dentures, orthodontic retainers, occlusal splints, aligners, and metal frameworks. It is ideal for removing light scratches, refining contours, and smoothing surfaces after coarser grinding. The wheel�s fine abrasive properties ensure minimal material removal while producing a clean, satin-like surface finish that transitions seamlessly to polishing compounds. Aluminum oxide abrasives provide outstanding durability, consistent cutting action, and long wear life. Unlike coarser wheels, the 400-grit wheel provides gentle abrasion that preserves detail and prevents over-thinning of dental appliances. It is especially beneficial for fine-edge work, such as smoothing gingival margins, contouring flanges, or finishing thin splint edges. The 3/8" arbor ensures secure mounting on standard laboratory mandrels, maintaining stable rotation for precise control. Reduced vibration helps technicians create smooth, uniform finishes without unintended gouging or uneven surfaces. This is particularly important when working with delicate sections of acrylic appliances or precision-fit resin components. The wheel�s 2-inch diameter allows excellent handling in both small and medium-size dental devices. Its fine grit also minimizes heat buildup, protecting heat-sensitive materials from distortion or surface damage. Whether preparing acrylic for buffing compounds, refining metal frameworks before polishing, or performing detailed smoothing of resin components, the 2" AO Unmounted Wheel � 400 Grit delivers consistent, high-quality results. It is an essential tool for achieving the refined surfaces required in modern dental appliance fabrication.
