Norton 69014192179 Double End Diamond Hone 220 400 Grit

Product Description

The NORTON 69014192179 is a double end diamond hone designed for precision sharpening and honing of hard materials including carbide, ceramic, and hardened steel. Each end carries a different grit — 220 on one end for very fine cutting and 400 on the other for super fine finishing — giving the technician two stages of refinement in a single compact tool. The rectangular hone measures 0.375 inches wide by 0.25 inches high with a 1 inch length of cut and 4 inches overall length, making it easy to control during hand honing operations. Diamond concentration is 100 percent, ensuring consistent abrasive performance across the full cutting surface.

This hone is suited for sharpening cutting tools, deburring precision components, and refining edges on toolroom and maintenance applications. The double end configuration reduces the need to switch between separate honing sticks when progressing through grit stages. At 0.06 pounds, it is light enough for bench work or field use by machinists, tool grinders, and maintenance technicians working on tight tolerances. The 1 inch length of cut is appropriate for narrow slots, grooves, and small radius surfaces where larger hones cannot reach.

Key Features

• Dual grit design: 220 grit very fine on one end, 400 grit super fine on the other
• 100 percent diamond concentration for consistent, long-lasting abrasive performance
• Rectangle hone shape with 1 inch length of cut for access to tight geometries
• Compact 4 inch overall length for controlled hand honing
• Single-piece double end format eliminates need to swap between two separate sticks

Compatibility

Designed as an OEM-style replacement or direct-use honing stick for bench and hand honing applications on carbide, ceramic, hardened steel, and similar hard-material workpieces requiring fine to super fine surface finishing.

Installation Notes

This hone is used by machinists, toolmakers, and maintenance technicians in hand honing operations — no power tools or permanent installation required. Keep the hone surface clean and use an appropriate honing fluid or water to extend abrasive life and reduce loading. Inspect the hone for cracks or uneven wear before each use. Store in a protective case or sleeve to prevent chipping the diamond surface.
