Brush Research Mfg. BC12M2500CD Flexible Cylinder Hone

Product Description

The BRUSH RESEARCH MFG. BC12M2500CD is a flexible cylinder hone designed for precision bore finishing in carbide, ceramic, and hardened tool steel. Rated at 2,500 grit with a diamond abrasive, this tool delivers extra fine surface conditioning in bores up to 0.47 inches in diameter. The overall length is 8 inches, with an abrasive length of 2.5 inches and a shank diameter of 0.168 inches. It is intended for use in machine shops, engine rebuilding environments, and toolroom applications where tight bore geometry and fine surface finish are required. Metalworking professionals and machinists are the primary installers and operators of this tool.

This hone is suited for small-bore applications in hardened materials where conventional abrasives perform poorly. The diamond abrasive construction makes it effective on carbide dies, ceramic components, and hardened tool steel bores. It is commonly used in production finishing, tooling maintenance, and precision repair work. Maximum operating speed is 1,200 RPM. The 0.47-inch maximum bore diameter targets small-bore work typical in hydraulic components, fuel system parts, and precision tooling fixtures.

Key Features

• Diamond abrasive at 2,500 grit for extra fine bore finishing
• Compatible with carbide, ceramic, and hardened tool steel materials
• Maximum bore diameter of 0.47 inches for small-bore applications
• Abrasive length of 2.5 inches for consistent contact across the bore
• Shank diameter of 0.168 inches fits standard drill chucks and flexible shaft tools
• Maximum operating speed of 1,200 RPM

Compatibility

Designed for use in bores up to 0.47 inches diameter in carbide, ceramic, and hardened tool steel workpieces. Verify bore diameter and material hardness before use to confirm fitment.

Installation Notes

This tool is operated by machinists and metalworking professionals using a drill press, hand drill, or flexible shaft machine. Secure the shank firmly in the chuck before operation and do not exceed 1,200 RPM. Always wear appropriate eye protection and follow shop safety procedures when honing hardened materials. Inspect the abrasive segments for wear before each use and replace the tool if segments are damaged or unevenly worn.
