Norton 041220003312 Diamond Grit Grade 3 Super Finishing

Product Description

The NORTON 041220003312 is a diamond grit lapping and super finishing compound in a 5-gram container. This compound uses fine diamond particles ranging from 1 to 5 microns to produce controlled surface finishes on hard materials. Grade 3 places it in the fine abrasive range, making it suitable for final-stage lapping, honing, and polishing operations where tight surface tolerances are required. Machinists, tool and die makers, and precision maintenance technicians use this compound when conventional abrasives cannot achieve the required finish quality on hardened steel, carbide, ceramics, and similar materials.

This diamond grit compound is used in precision metalworking, toolroom operations, and maintenance applications requiring super finishing. It applies to lapping flat surfaces, honing bores, and polishing cutting edges on hardened tool steel and carbide tooling. The 5-gram container size suits bench-level work and spot finishing tasks rather than high-volume production runs. It is appropriate for both shop floor maintenance and precision grinding room environments.

Key Features

• Grade 3 diamond compound formulated for super finishing applications
• Micron grit range of 1 to 5 microns for fine surface refinement
• Yellow color coding identifies the Grade 3 grit classification for quick shop identification
• Compact 5-gram container suited for bench work and precision touch-up tasks
• Compatible with hardened steels, carbide, ceramics, and other hard substrates

Compatibility

Designed for use as a fine-grade diamond lapping and super finishing compound on hard materials including tool steel, carbide, and ceramics where a 1 to 5 micron finish is required.

Installation Notes

Apply a small amount of compound to the lapping surface, lap plate, or honing tool using a clean applicator. Work the compound in controlled strokes under consistent pressure to avoid uneven material removal. Clean the workpiece and tooling thoroughly between grit stages to prevent cross-contamination with coarser abrasive particles. Follow shop safety practices for handling fine abrasive compounds, including appropriate eye and skin protection.
