Item Name: Covington Parts - Flat Lap - Brass Shaft Adapter SKU: COVCBA045 Description: This flat lap brass shaft adapter is a machined brass fitting used to adapt one shaft size or mounting style to another on flat lap and lapidary-style grinding equipment. It is constructed from solid brass for corrosion resistance and stable, true running performance. The adapter is designed to center and secure a lap disc or accessory so it spins evenly, helping reduce wobble and vibration that can cause uneven grinding, inconsistent bevels, or poor polish quality on glass. How it is used: Use this adapter when you need to mount a lap disc or accessory that does not match the shaft or arbor size on your flat lap. Install the adapter onto the machine shaft, then secure the lap disc so it runs centered and true. A properly fitted adapter improves control during coldworking tasks like flattening bases, smoothing cut edges, shaping bevels, and polishing glass surfaces because the disc tracks consistently without chatter.
