FLEX-HONE 3-1/2 in Silicon Caroffere 120 Grit Cylinder Hone GB31212
The Flex-Hone GB31212 is a 3.5\" diameter, 120-grit Silicon Caroffere flexible cylinder hone manufactured by Brush Research Manufacturing (BRM). It is primarily designed to deglaze, deburr, and create a cross-hatched surface finish in 3.5-inch cylinders (such as engine blocks and hydraulic tubes). [1, 2]
To ensure a high-quality finish and maximize the life of your tool, follow these operating parameters and steps: [3]
Operating Parameters Bore Diameter: 3.5 inches (89 mm) Recommended Spindle Speed: 350 to 600 RPM Maximum RPM: Not to exceed 900 RPM Stroke Speed: 120 to 180 inches per minute (a smooth, continuous stroke) Required Lubricant: Always use honing oil or a high-quality lubricant (like 10W-30 motor oil for engine blocks) to prevent the tool from loading up with metal. [1, 3, 4, 5] How to Use the Tool Lubricate: Generously apply honing oil to both the cylinder wall and the Flex-Hone brush before you begin. Start Rotation: Ensure the drill or spindle is rotating before entering the cylinder. Insert & Stroke: Insert the spinning hone into the bore and stroke it back and forth continuously. Time & Angle: Hone only long enough to achieve a cross-hatch pattern with a ≈ 45° angle (usually just 10 to 30 seconds). Remove: Continue rotating the tool until it is completely removed from the cylinder. [3, 4, 6, 7] Cleaning Up
Proper cleaning is the most important step after honing to remove abrasive debris. Scrub the cylinder thoroughly with warm, soapy water and a nylon brush. Dry the cylinder completely, then wipe the wall with a lint-free cloth and a light coat of oil to prevent flash rusting. [4]
If you\'d like to narrow down your setup, let me know:What material are you honing (e.g., cast iron, steel, aluminum)?What machine are you attaching the hone to (handheld drill, drill press, or lathe)?
