• QUALITY — Proudly Made in the USA. Quality and consistency you can count on made from the inventors and makers of the tool.
• DESIGN — The FLEX-HONE is intentionally manufactured oversized. This engineered oversize creates the optimal amount of pressure inside the cylinder wall allowing the tool to be self-centering, self-aligning and self-compensating for wear and easy use.
• FINISHING BENEFITS — Offered in a wide variety of grits to achieve specific finishing tolerances as well as a beautiful crosshatch finish. Ideal for rebuilding hydraulic and pneumatic cylinders, engine and brake cylinders, valve guides, pumps, compressors and more.
• CROSSHOLE DEBURRING — Accomplish finishing and deburring simultaneously in a single setup. Can be used in virtually any rotating spindle from a hand drill, drill press or CNC equipment.
• 180 GRIT SILICON CARBIDE ABRASIVE — Excellent on mild steel, stainless steel, cast iron and other softer ferrous materials. Typically achieves a finish of 30 - 40 Microinch (.7 - 1 Micrometer).
• WHAT'S INCLUDED — 1 Each of a GBD Heavy Duty FLEX-HONE: 3.000" (76mm) Bore Diameter, 5" Abrasive Part Length, 0.310" Shank Diameter, 13.5" Overall Length. For Use on Bore Diameters Between 2.751"-3.000". PLEASE NOTE: ORDER BY BORE SIZE.

• Select the Correct Bore Size — Measure your cylinder bore accurately and choose a Flex-Hone slightly oversized for self-centering fit.
• Apply Honing Oil — Lubricate the bore with honing oil to reduce heat and abrasive wear, ensuring a smooth finish.
• Operate at Recommended RPM — Insert the Flex-Hone into a drill or CNC, run at 500-1200 RPM, and move in and out steadily for 10-15 minutes.
• Clean and Inspect — Remove the tool, clean the cylinder, and inspect the cross hatch pattern for desired finish. Repeat if necessary.
