Brush Research Flex Hone, 3in Engine 180 Grit BC30018

Features and Benefits:

• The BC 3 inch Flex-Hone surface finishing and deburring tool is designed for nominal bore sizes between 2.875 IN and 3.000 IN. This tool features 3.00 IN of abrasive globules which are composed of 180 grit Silicon Carbide and are excellent for mild steel, stainless steel and cast iron. 180 grit generally provides an Ra Finish range of 30 - 40 Microinch (.7 - 1 Micrometer). Significant changes in surface finish may require multiple grits to achieve the desired result. Overall tool length is 8 IN long and has a twisted wire stem for use in any collet, chuck, or similar holding device. The maximum speed for this diameter tool is between 600 - 900 RPM and a general feed rate of 150 - 250 ipm. Flex-Hone Tools are produced in an oversized condition by the manufacturer. Always order by your nominal bore diameter. If your nominal bore size is between standard sizes, order the next larger size.
• The Flex-Hone Tool is a resilient, flexible honing tool used to improve the internal surface finish while also being able to deburr a bore or cylinder. It is comprised of abrasive globules laminated onto the ends of flexible nylon filaments. Its unique construction allows the tool to be self-aligning, self-centering and self-compensating for wear. The tool provides the benefit of removing loose, torn and folded metal and creating a substantial flat or plateau surface. An additional important application for the Flex-Hone Tool is burr removal from cross-drilled holes and slots. The Flex-Hone is designed for a variety of automotive, hydraulic, pneumatic and industrial applications in sizes from 4mm 36'. The plateau finish achieved by the tool will provide better oil retention and sealing surfaces without changing bore geometry. Brush Research Manufacturing embraced the benefits of plateau finish and pioneered the concept of plateau honing, culminating in the introduction of the Flex-Hone Tool in 1972. The Flex-Hone Tool was originally created to deglaze cylinder walls in automotive applications and has gained many nicknames over the years including ball hones, flexihone, dingleberry hone, bead brush, glaze breaker, and glaze buster.
• In general, when operating, always have the tool rotating before entering the bore and direction of revolutions should not change while inside the piece. To avoid damage to the tool and maintain operation safety, do not run the tool at high speeds while unsupported outside of the intended bore. Do not apply a side load to the shank or stem and do not exceed manufacturer's recommendation for speed of rotation. Speed should be reduced on entry and exit of the intended bore to avoid any oscillation which may compromise the integrity of the shank or stem. Always use with ample lubricant or honing oil, do not use solvents.
