Norton 66260300398 Super Fine Diamond Lapping Compound 3 Micron

Product Description

The NORTON 66260300398 is a super fine diamond lapping compound packaged in an 18 gram plastic syringe for controlled, precise application. Formulated with diamond abrasive at a maximum grit size of 3.00 microns, it delivers consistent, fine surface finishing on hard and challenging materials. The syringe format minimizes waste and allows the technician to dispense compound directly onto the workpiece or lapping tool without contamination. This compound is intended for machinists, tool-and-die makers, and precision trade professionals performing surface refinement, flatness correction, or edge honing on ferrous and carbide substrates.

This compound is suited for precision lapping and polishing operations in machine shops, tool rooms, and production maintenance environments. It performs on a wide range of ferrous materials including 304 series stainless, 400 series stainless, ductile iron, gray iron, hard carbon steels, soft carbon steels, tool steels, and carbide. Typical applications include lapping valve seats, mating surfaces, cutting tools, and precision instrument components where surface finish is critical to performance and fitment.

Key Features

• Super fine diamond abrasive at 3.00 micron maximum grit for high-precision surface finishing
• 18 gram plastic syringe container for controlled dispensing and reduced compound waste
• Compatible with a broad range of ferrous and carbide materials including stainless steels, cast irons, carbon steels, tool steels, and carbide
• Diamond abrasive provides consistent cut rate on hard substrates that resist conventional abrasives
• Single-unit packaging suitable for bench use, field service, and low-volume precision work

Compatibility

Rated for use on 304 series stainless, 400 series stainless, ductile iron, gray iron, hard carbon steels, soft carbon steels, tool steels, and carbide workpieces.

Installation Notes

Applied by machinists and precision tradespeople using lapping plates, laps, or hand tools appropriate to the workpiece geometry. Clean and degrease mating surfaces thoroughly before applying compound to ensure consistent abrasive action. Use only the amount of compound needed for the pass and avoid cross-contaminating grit sizes when working through a progression. Store the syringe capped and away from heat to preserve compound consistency.
