CYLINDER BORE FINISH TOOLS
With minimal stock removal and without damaging or changing the micro sub-structure of the
metal, the Flex-Hone tool plateaus the surface, removes cut, torn and folded metal creating a
cross-hatched finish that retains a film of oil, reducing friction, ring wear and the factors that
lead to scuffing. In hydraulics and two-stroke engines there is the double benefit of radiusing the
ports and finishing the cylinder walls in a single operation.
FLEXHONE GRITS
We supply the standard grits in silicon carbide recommended by the manufacturer of Flex-Hone
and Hastings Piston Ring Engineers. The BC 4-1/8" 320 grit (H1735A) is for use on racing
engines. Flexhone grits cannot be compared to stone type grits.
