Brush Research FLEX-HONE, 1 1/4", 180 grit

Proudly Made in the USA. Quality and consistency you can count on made from the inventors and makers of the tool.

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.

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.

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 ZIRCONIA ALUMINA #1549 ABRASIVE]-Excellent on low carbon to medium carbon steels, stainless steel and cast iron. Also beneficial when you are looking for a more aggressive tool (ie deburring) compared to Silicon Carbide. Typically achieves a finish of 30 - 40 Microinch (.7 - 1 Micrometer).
