Norton 69014192180 Double End Diamond Hone 320 400 Grit

Product Description

The NORTON 69014192180 is a double end diamond hone designed for precision sharpening and honing of hardened tool steels, carbide edges, and other hard materials. Each end carries a different grit — 320 on one end and 400 on the other — allowing a technician or toolmaker to step through abrasive grades without switching tools. The rectangular abrasive face measures 0.375 inches wide by 0.0625 inches high by 1 inch in cutting length. The full tool is 4 inches in overall length, making it easy to control by hand in tight work areas. Diamond abrasive at 100 percent concentration ensures consistent stock removal and long service life compared to conventional abrasive hones.

This double end diamond hone is suited for sharpening and deburring applications in machine shops, tool rooms, and field service environments. Trades that commonly use this type of hone include machinists, die makers, tool and die grinders, and maintenance technicians working with carbide tooling, precision gauges, hardened punches, and mold components. The compact 4 inch overall length fits into a standard tool pouch or kit bag, making it practical for on-site use as well as bench work.

Key Features

• Dual grit configuration: 320 grit on one end, 400 grit on the other end for two-stage honing in one tool
• 100 percent diamond concentration for consistent, aggressive cutting action on hardened materials
• Rectangular hone shape with 1 inch abrasive length for controlled contact on flat and edge surfaces
• Compact 4 inch overall length suits both bench and portable field use
• Lightweight at 0.06 pounds — minimal added weight to a tool kit
• Single-piece double end design reduces the need to carry multiple honing sticks

Compatibility

Designed as an OEM-style replacement or direct-use honing tool for applications requiring fine to super-fine grit diamond abrasives on hardened steels, carbide, ceramics, and similar hard materials.

Installation Notes

No power tools or mechanical fastening is required — this hone is used by hand with light, controlled strokes against the workpiece. Keep the abrasive face flat against the surface being honed to avoid uneven wear. Clean the diamond face periodically with a stiff brush and water or light solvent to clear swarf buildup and maintain cutting efficiency. Follow all applicable shop safety practices, including eye protection, when working with metal edges and abrasive tools.
