Proudly made in the USA by Brush Research Manufacturing, it combines deburring and finishing in one step, enhancing seal life and oil retention across hydraulic, pneumatic, and engine cylinders with effortless compatibility on common rotating spindles. ## 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 ## Features - [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 BC Standard Duty FLEX-HONE: 1.000" (25.4mm) Bore Diameter, 3" Abrasive Part Length, 0.228" Shank Diameter, 8" Overall Length. For Use on Bore Diameters Between 0.939"-1.000". PLEASE NOTE: ORDER BY BORE SIZE. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002XUL040 | | Best Sellers Rank | #2,872 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Flex Hones | | Brand | Flex-Hone | | Brand Name | Flex-Hone | | Bristle Type | Abrasive Globule Bonded To Flexible Nylon Filament | | Color | Gray | | Compatible Material | Cast Iron, Mild Steel, Other Softer Ferrous Materials, Stainless Steel | | Customer Reviews | 4.7 out of 5 stars 549 Reviews | | Grit Material | Silicon Carbide | | Grit Material Type | Silicon Carbide | | Grit Number | 180 | | Grit Type | 180 | | Included Components | BC 1" (25.4MM) 180SC FLEX-HONE | | Item Diameter | 1 Inches | | Item Dimensions | 8 x 2.8 x 0.1 inches | | Item Dimensions L x W | 8"L x 2.8"W | | Item Type Name | Brush Research BC10018 FLEX-HONE®, 1" (25.4mm) Diameter, 180 Grit, Silicon Carbide, For Mild Steel, Stainless Steel, Cast Iron and Softer Ferrous Materials | | Item Weight | 0.01 Ounces | | Manufacturer | Brush Research Manufacturing | | Material | Silicon Carbide | | Material Type | Silicon Carbide | | Model | BC10018 | | Number of Items | 1 | | Number of Pieces | 1 | | Part Number | BC10018 | | Product Dimensions | 8"L x 2.8"W | | Recommended Uses For Product | Deburring, Finishing | | UPC | 843469115232 | | Unit Count | 1 Count | | Warranty Description | Manufacturer Warranty | ## Product Details - **Brand:** Flex-Hone - **Bristle Type:** Abrasive Globule Bonded To Flexible Nylon Filament - **Grit Material:** Silicon Carbide - **Material:** Silicon Carbide - **Product Dimensions:** 8"L x 2.8"W ## Images ![SILICON CARBIDE - BC FLEX-HONE-Standard Duty for Small Diameters - Image 1](https://m.media-amazon.com/images/I/71Y6c3HtzAL.jpg) ![SILICON CARBIDE - BC FLEX-HONE-Standard Duty for Small Diameters - Image 2](https://m.media-amazon.com/images/I/71Jfdmgkh3L.jpg) ![SILICON CARBIDE - BC FLEX-HONE-Standard Duty for Small Diameters - Image 3](https://m.media-amazon.com/images/I/71EZRkPmdaL.jpg) ![SILICON CARBIDE - BC FLEX-HONE-Standard Duty for Small Diameters - Image 4](https://m.media-amazon.com/images/I/81aPGQTXemL.jpg) ![SILICON CARBIDE - BC FLEX-HONE-Standard Duty for Small Diameters - Image 5](https://m.media-amazon.com/images/I/81X4pgWlJtL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ One fantastic produc *by B***Z on November 16, 2021* 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.
