Ultrafinish Plateau Soft Hones

Goodson Tools & Supplies

Choose from multiple sizes of Ultra-Finish Plateau Soft Hones for portable drills; listed smallest to largest below.

  • Remove microscopic peaks and scuffs without enlarging bores
  • Use with a portable drill
  • Abrasive impregnated nylon bristles
  • Ideal for high performance engine building and for engines that use low-tension rings
  • Use after honing
  • Give a superior plateau finish so rings seal immediately, reducing break-in time
  • Allows closer tolerances for improved compression, better oil control and lower emissions
  • For best results use with liberal amount of honing oil.
  • Not interchangeable with Flex-Hones®

NOTE: Right hand rotation only. For best results, keep your RPM about the same as your hone RPM. Use the same rate of speed and number of strokes.
