The rounded stainless-steel pins from OTEC are developed for wet finishing and are particularly suitable for professionals who demand a high-quality surface finish – even on complex and hard-to-reach areas.

The pins are used for polishing, mirror-finish polishing and pressure deburring of precious metals. During processing, no material is removed from the workpiece. Instead, the surface is smoothed and compacted, resulting in a denser structure and a significantly improved finish without affecting dimensions or fine details.

The rounded ends are a key advantage compared to conventional pins with sharp edges. The rounded geometry ensures more efficient and even polishing, reduces the risk of marks, and delivers a more homogeneous, high-gloss result – even on fine structures, internal surfaces and filigree jewellery components.

Manufactured from stainless-steel, the pins offer a long service life and consistent performance, even with repeated use in wet finishing processes. They function as an effective polishing medium in OTEC’s finishing systems and comparable equipment, where reproducible results and efficient post-processing are essential parts of daily production.
