Brush Research P10028N Flex-Hone Cylinder Honing Tool 1.00" Bore 28 Grit

The Brush Research P10028N is a flexible cylinder honing tool from Brush Research Manufacturing's industry-leading Flex-Hone line. Engineered for use in 1.00-inch bore applications, this ball hone uses abrasive globules mounted on flexible filaments to produce a precise, controlled surface finish inside cylinder bores, brake cylinders, hydraulic cylinders, and other cylindrical components.

Unlike rigid honing tools, the Flex-Hone is self-centering and self-aligning, meaning it conforms to the bore rather than requiring perfect tool alignment. The flexible action removes burrs, surface irregularities, and light oxidation while simultaneously generating the crosshatch pattern required for proper oil retention and ring seating in engine applications.

Key Features:

• Bore Size: 1.00 inch (25.4 mm) diameter
• Grit: 28 grit — aggressive cutting action for material removal and surface conditioning
• Abrasive globules bonded to flexible nylon filaments for self-centering action
• Produces a controlled plateau crosshatch finish for optimal oil retention
• Removes burrs, edge breaks, and surface defects from cylinder walls
• Compatible with standard drill motors and CNC equipment
• Suitable for use with honing oil or cutting fluid for best results
• Manufactured in the USA by Brush Research Manufacturing

The Brush Research Flex-Hone is trusted by automotive engine builders, hydraulic system technicians, and industrial machinists worldwide. It is ideal for cylinder reconditioning, brake caliper bores, master cylinders, and precision bore finishing across automotive, marine, and industrial applications.
