Flex-Hones, 3.0 - 8.0 Inch, GBD Heavy Duty
The GBD Series Flex-Hone tools are designed for bore diameters from 3" thru 8" in a twisted-in-wire construction. 3 thru 4-1/2" diameter tools are 13 -1/2" OAL. 5" thru 8" diameter tools are 17-1/2" OAL. Heavy-duty Flex-Hones are commonly used for block cylinders or liners, stationary diesel, oil and gas pipes, marine engine and may other applications. The heavy duty tool is recommended for large diameter or high production applications.

The Flex-HoneŽ tool is always used in an oversized condition. Our sizes are listed by the nominal bore in which the hone is intended to be used.
