What believers are saying

  • Direct sales and customization support repeat industrial accounts needing fast specification changes.
  • International positioning remains intact through its English site and export-oriented product lineup.

What critics are saying

  • Public footprint is tiny: LinkedIn listed 7 followers and 11-50 employees in 2026.
  • The website showed no visible 2026 launches, hiring surges, or expansion announcements.
  • A larger Taiwanese or Chinese abrasive supplier can commoditize wheels and squeeze margins quickly.

What makes JRM unique

  • It customizes size, hardness, and thickness for metal, wood, and nonmetal finishing.
  • Its catalog spans non-woven wheels, cloth wheels, abrasive belts, and industrial brushes.
