Item Details

  • The Dynabrade 11240 is an industrial-grade extended-reach abrasive belt tracking and grinding attachment manufactured in the United States. It is designed as an exact-fit component for Dynafile series portable pneumatic and electric abrasive belt systems to facilitate material removal, blending, and polishing in narrow geometries and channels.

Features

  • Extended 9-inch reach geometry for accessing deep channels, weldments, and pipe IDs
  • Dual-zone grinding functionality allowing for point grinding on the wheel or flat blending on the platen
  • Self-centering crowned wheel profile uses centrifugal force to maintain belt alignment
  • Soft-density platen pad provides damping to prevent gouging and focal heat stress
  • Toolless interchangeability with Dynafile tensioning spring-lock blocks
  • Precision-ground dual internal bearings for reduced vibration and minimum run-out
  • Vulcanized rubber wheel bonded to rigid core for impact absorption and surface conformity
  • High-tensile steel arm body prevents bending or deflection during aggressive grinding
