Tired of inconsistent cylinder honing results? This tool is specifically engineered to solve that problem, delivering a perfect cross-hatch finish every time. Ideal for engine rebuilds, hydraulic cylinder repairs, and precision deburring.Core Advantages Wide Applicability: Suitable for cylinders with bore diameters ranging from 3.751 to 4.000 inches. Features a 6-inch abrasive length, 13.5-inch overall length, and 0.31-inch tool shank diameter to meet diverse machining needs.240-Grit Silicon Carbide Abrasive: Optimized for low-carbon steel, stainless steel, cast iron, and soft ferromagnetic materials, delivering a 24-32 microinch surface finish for efficient, precise machining.Self-Adjusting Design: Achieves self-centering and self-alignment through optimal pressure, ensuring easy operation with rotary spindles like hand drills, drill presses, and CNC equipment.Wide Applications:Used for repairing cylinders, hydraulic systems, engines, brake cylinders, valve guides, etc., delivering precise tolerances and cross-hatch texture effects.Optimal Performance Tip:For optimal results and to extend tool life, use sufficient lubricant during operation.

• Package Includes: 1 cylinder hone, suitable for bore diameters ranging from 3.751" to 4.000". Its abrasive length is 6“, shank diameter is 0.31“, overall length is 13.5“, and bore diameter is 4.000“.
• Cylinder Hone Tool: Achieves self-centering, self-alignment, and self-compensating wear through optimal pressure for easy operation. Capable of finishing and deburring, compatible with various rotating spindles from hand drills and drill presses to CNC equipment.
• 240-Grit Silicon Carbide Abrasive: Ideal for machining softer ferromagnetic materials such as aluminum, brass, bronze, low-carbon steel, stainless steel, and cast iron. Delivers a surface finish of 24–32 microinches for efficient processing.
• Wide Application: Delivers precise tolerances and beautiful crosshatch finishes, widely used for restoring hydraulic cylinders, pneumatic cylinders, engine, brake cylinder, valve guides, pumps, and compressors and more.
• Purchase Note: Flex hone are manufactured slightly oversized; order based on bore diameter. Brush dimensions may exceed specifications by approximately 10%, but the tool shaft's flexibility ensures precise adaptation to cylinder diameters. Apply ample lubricant before use.
