Norton 69014192178 Double End Diamond Hone 220 320 Grit

Product Description

The NORTON 69014192178 is a double end diamond hone designed for precision sharpening and honing of hard materials including carbide, ceramic, and hardened steel. This tool features two abrasive ends in Very Fine (220 grit) and Extra Fine (320 grit), allowing the technician or tradesperson to move through progressive grits without switching tools. The rectangular hone profile measures 0.375 inches wide by 0.25 inches high with a 1 inch length of cut and 4 inches overall length, making it well-suited for tight access areas. With 100 percent diamond concentration, the abrasive surface delivers consistent material removal across the full cutting face.

This double end hone is used by HVAC technicians, plumbers, electricians, machinists, and general trade professionals who need to deburr, touch up, or restore edges on precision components in the field or shop. The compact 4 inch overall length fits easily in a tool pouch or service bag. The 220 grit end handles initial sharpening and edge restoration, while the 320 grit end is used for finishing and refining the edge to a finer surface. It is appropriate for use on valve seats, orifices, drill bits, chisels, and similar small cutting or sealing surfaces encountered in trade service work.

Installation Notes

This hone is a hand tool requiring no power source or mounting hardware. Use light, consistent pressure with a lubricant such as water or honing oil to extend abrasive life and improve surface finish. Keep the hone flat against the work surface to maintain a consistent edge angle. Inspect the abrasive surface periodically for glazing or loading and clean as needed.
