Brush Research Mfg. BC10M24 Flexible Cylinder Hone 240 Grit

Product Description

The BRUSH RESEARCH MFG. BC10M24 is a flexible cylinder hone designed for deburring, surface finishing, and controlled material removal inside small-diameter bores. Built with silicon carbide abrasive at 240 grit (extra fine grade), it delivers consistent finish quality in tight bore applications where rigid tooling cannot conform to bore geometry. The overall length is 8 inches, with a 2-inch abrasive length and a 0.14-inch shank diameter. Maximum rated speed is 1,200 RPM. This tool is used by machinists and maintenance technicians working on precision bore finishing across a range of ferrous and non-ferrous base materials.

The BC10M24 is suited for finishing bores up to 0.39 inches in diameter. Typical applications include cylinder bores, valve bodies, hydraulic components, and small mechanical assemblies requiring a refined surface finish. Compatible material applications include mild steel, stainless steel, and cast iron. The extra fine 240 grit designation makes it appropriate for final finishing passes rather than aggressive stock removal, particularly in close-tolerance bore work found in both production and repair settings.

Key Features

• Silicon carbide abrasive at 240 grit for extra fine surface finishing
• Maximum bore diameter of 0.39 inches (10 mm) for small-bore applications
• 2-inch abrasive length provides consistent contact through the bore
• 8-inch overall length allows reach into recessed bore locations
• Rated to 1,200 RPM for use with standard drill or honing equipment
• Compatible with mild steel, stainless steel, and cast iron workpieces

Compatibility

Designed for use in bores up to 0.39 inches in diameter in mild steel, stainless steel, and cast iron components. Suitable for use with standard drill presses, portable drills, and honing machines capable of operating at or below 1,200 RPM.

Installation Notes

This tool is installed and operated by machinists or maintenance technicians using a drill press or hand drill at controlled speed. Do not exceed the 1,200 RPM maximum rated speed, as overspeed can damage the abrasive balls and reduce tool life. Ensure the workpiece is secured before operation and use an appropriate cutting fluid or lubricant to extend abrasive life and improve surface finish. Wear appropriate eye and hand protection during use.
