Description

OTEC Walnut Shell Media H1/100 is a dry polishing media used for achieving high-gloss finishes on non-ferrous metals, jewelry alloys, titanium, and steel. The H1/100 grade is a medium grain size designed as the first step for dry pre-polishing in multi-stage finishing processes. This media is pre-impregnated with polishing compound, so no additional paste is needed until the 3rd or 4th cycle.

Features

  • Dry walnut shell media pre-impregnated with polishing paste
  • H1/100 medium grain for first-step dry pre-polishing
  • Suitable for non-ferrous jewelry metals, titanium, and steel alloys
  • Works in OTEC dry disc finishers and most dry polishing equipment
  • Refresh compound after 3rd–4th use with OTEC P6 Polishing Paste

Notes

  • Suitable for cast and fabricated jewelry parts, including rings, pendants, findings, and small components.
