## Overview

The Brush Research BC10018 FLEX-HONE® is a 1-inch diameter, 180 grit silicon carbide honing tool designed for mild steel, stainless steel, cast iron, and softer ferrous materials. Engineered with an oversized, self-centering design, it delivers a consistent crosshatch plateau finish that enhances oil retention and seal life. Made in the USA, this versatile tool deburrs and finishes in one step, compatible with hand drills, drill presses, and CNC machines, making it a must-have for professionals seeking precision and efficiency in cylinder honing.

## 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: One fantastic produc - Used this to hone both cylinders of a 22 hp Briggs VTwin lawn tractor engine that needed a new connecting rod, a new piston and 2 sets of rings. Honing the cylinders is needed to allow the rings to break in and seat properly. Since I don’t expect to do this regularly I was between a cheap set of honing stones for around $20 and the Flex hone which I’d seen on YouTube and was selling on desertcart for $37. The reviews on the honing stones were terrible (cheaply made and inconsistent result) and the flex tool reviews while not numerous were mostly positive. Several excellent YouTube videos by the manufacturer and a call to the seller about whether the 3 inch (180 grit) tool would be good for my 2.96 inch cylinder convinced me it would be worth the extra cost for the Flex hone tool. What a FANTASTIC result in less than 10 minutes to do both cylinders following the video instructions of coating the tool with clean oil and moving in and out of each cylinder for 1 minute. Perfect cross hatched pattern on both. Great tool and good value considering the $200 of parts and many hours of labor to complete this project.
Review: product - works well
