Best Abrasive Mechanics in 2026

After weeks of use in my vibratory tumbler, the difference in surface finish is undeniable. This Interactivia walnut shell media provides a remarkably fine 18-40 grit consistency that polishes delicate substrates without the aggressive scratching you get from harder abrasives. Because it is made of 100% crushed walnut shells, it feels like a much more environmentally friendly way to handle sensitive finishing tasks. I found that staying within the recommended 20-60 PSI range is vital. If you push past 80 PSI, you’ll definitely see the media break down faster. It is a reliable, American-made solution for anyone needing a gentle touch for blasting or tumbling projects.

Can you actually achieve a professional-grade polish without risking permanent damage to your delicate substrates?

Because these are 100% crushed walnut shells, they serve as an environmentally friendly alternative to harsher synthetic media.
