Product Details

Surface finish that survives the QA bench. Built around production grinding and sanding cycles, the J-4421-4 delivers production-grade results. Equipped with a 3 HP motor and industrial-grade construction throughout, it handles full-capacity operation across long production cycles. Industrial-grade construction, industrial-grade warranty.

Features

  • Industrial-grade 3 HP three-phase drive — running quieter and cooler than equivalent open-frame designs, built for professional shop floors.
  • Precision-rated abrasive belt drive — handling the abrasive media library production finishing uses across production finishing.
  • Continuous-duty belt design handles the abrasive cycle counts for the belt-length production finishing depends on.
  • Production-spec disc geometry supports flat grinding for the disc-finishing envelope production work demands.
  • Industrial tilting table — delivering angle-grinding authority production finishing demands across industrial finishing.
  • Production-grade cast iron reference surfaces dampen harmonics across production runs.
