## Overview

The Flex-Hone Brush BC11412 is a 1.25-inch diameter, 120 grit silicon carbide abrasive tool designed for precision honing and deburring. Made in the USA, it features a self-centering, self-aligning, and self-compensating design that ensures consistent, high-quality finishes with an oil-retentive crosshatch pattern. Ideal for a wide range of ferrous materials, it streamlines finishing and deburring in one step, offering machinists customizable abrasive options for superior surface preparation and extended seal life.

## Description

The Flex-Hone® tool was originally created by Brush Research Manufacturing to deglaze cylinder walls in automotive applications. Brush Research embraced the benefits of a plateau finish and pioneered the concept of plateau honing culminating in the introduction of the Flex-Hone tool in 1972. The Flex-Hone has gained many nicknames over the years and including ball hone, ball style hone, flexihone, dingleberry hone, bead brush, glaze breaker and glaze buster. Flexible honing with the Flex-Hone tool produces an oil holding cross hatch pattern and a true plateau finish free of cut, torn and folded metal. Any type or size of cylinder can benefit from the Flex-Hone®. These abrasive bead style brushes are produced in standard diameters from 4mm to 36 inches. Nine abrasive types are offered including silicon carbide, aluminum oxide, boron carbide and diamond allowing the tool to be tailored to finish any base material. A choice of 11 different grit selections are available for precise control of finish parameters. The elimination of peaks results in rapid ring seating, better oil control, reduced seepage in hydraulic and pneumatic applications and provides better seal performance and longer seal life. Successful applications include firearm chambers, shotgun barrels, musical instruments, combustion chambers, air compressors, pumps, valve bodies, valve guides, brake cylinders, wheel cylinders and the list goes on and on. Flex-Hone® tools are also very effective for deburring cross drilled holes, port radiusing and edge blending. Because of its unique construction, the Flex-Hone is self-centering, self-aligning, and self-compensating for wear so it does not require an elaborate set-up or special training. Deburring can be effectively automated and combined in the machining process to allow a complete cylinder finish in one operation or it can be employed as a secondary operation with equal results.

Review: Worked perfectly to hone a snowmobile cylinder
Review: All original! surprisingly on desertcart :) So I deglazed the 1973 RD350 barrels, used ATF had brilliant results in less than 15 pass. The hone quality is actually better than most back street workshop I've seen. A must have tool for anyone who love to tinker with Classis air-cooled!
