Research BC 3/4″ Brake Cylinder Flex-Hone 320SC Grit

The
BC Series Flex-Hone tool is
designed for use on any type or size of cylinder from 4mm up to 3″ in
diameter. This cylinder hone is designed for surface finishing and
cross hole
deburring in brake cylinders, wheel cylinders, hydraulics, pneumatics
and valve
guides. Additional abrasive types and grits are available.

• The
  FLEX-HONE process (Super finishing) produces a controlled surface
  condition unobtainable by any other method. It involves finish,
  geometry and metallurgical structure.
• A
  high percentage plateau free of cut, torn and folded metal (with
  radiused ports).
• A
  resilient, flexible, honing tool with a soft cutting action. The
  abrasive (points) globules each have independent suspension that
  assures the Flex-Hone to be self-center.
