- [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.
- [240 GRIT SILICON CARBIDE ABRASIVE]-Excellent on mild steel, stainless steel, cast iron and other softer ferrous materials. Typically achieves a finish of 24 - 32 Microinch (.6 - .8 Micrometer).
- [WHAT'S INCLUDED]-1 Each of a BC Standard Duty FLEX-HONE: 0.875" (22.2mm) Bore Diameter, 3" Abrasive Part Length, 0.228" Shank Diameter, 8" Overall Length. For Use on Bore Diameters Between 0.788"-0.875". PLEASE NOTE: ORDER BY BORE SIZE.

Select a product to estimate shipping.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.
Flex-Hone Benefits for Hobbyists, Machinists and High Volume Production Environments
SURFACE FINISHING APPLICATIONS
Working with machined parts often means ensuring a proper finish. The Flex-Hone creates repeatable finishing results with minimal setup or effort. The tool can be chucked in virtually any rotating spindle.
CROSSHOLE DEBURRING APPLICATIONS
Deburring is a costly operation for machinists. Even a small notch can cause moving parts to catch, creating the potential for accident. Deburr and finish cylinders in a single set with Flex-Hone Tools.
POLISHING & SINGLE RA FINISHING
achieve some of the most difficult finishing challenges with our large selection of grit and abrasive options. Finer grits are capable of achieving single RA finishes with minimal effort.
CONSISTENT PLATEAUED CROSSHATCH FINISHES
Deglaze cylinder walls with ease. A 45 degree crosshatch helps to seat piston rings and retains oil for lubrication. Also great for valve guides, piston pin bores, cam bearing bores and more!
Flex-Hone offers machinists the ideal combination of performance and value for professional finishing applications.
