Norton 041220009312 Diamond Grit Grade 9 Super Finishing 5g

Product Description

The NORTON 041220009312 is a diamond grit lapping and polishing compound formulated for super finishing applications. Supplied in a 5-gram container, this Grade 9 compound uses diamond abrasive particles in the 6 to 12 micron range to deliver a controlled, fine surface finish on hard materials. It is used by machinists, tool and die makers, and precision trades professionals who need repeatable, ultra-fine surface refinement on metal, carbide, ceramic, and similar substrates. The green color coding identifies the Grade 9 formulation, making it easy to manage when working with multiple grit stages.

This compound is suited for bench lapping, hand lapping, and precision honing operations in machine shops, tool rooms, and maintenance environments. It is typically applied to lapping plates, lapping films, or directly to a polishing tool or lap to refine sealing surfaces, valve seats, gauge faces, or cutting tool edges. The small 5-gram package size is practical for low-volume use and targeted touch-up work.

Key Features

• Grade 9 diamond grit compound with a 6 to 12 micron particle size range for super finishing
• Green color coding identifies grit grade and simplifies multi-stage lapping setups
• 5-gram container size suited for precision, low-volume polishing tasks
• Compatible with hard substrates including carbide, hardened steel, and ceramic
• Diamond abrasive provides consistent, long-lasting cutting action compared to conventional abrasives

Compatibility

Designed for use as a diamond lapping and super finishing compound on hard metals, carbide tooling, ceramics, and similar precision surfaces requiring a fine micro-finish.

Installation Notes

Apply this compound using a clean lapping tool, lap plate, or polishing stick appropriate for the workpiece material. Keep the compound free of cross-contamination from other grit grades, as mixing grit sizes will compromise surface finish results. Work in a clean environment and store the container sealed when not in use to prevent drying or contamination.
