The NORTON 041218005312 is a Grade 5 orange diamond grit lapping and super finishing compound supplied in a 5-gram container. Diamond grit compounds use precisely sized diamond abrasive particles suspended in a carrier medium to achieve ultra-fine surface finishes on hardened metals, ceramics, carbide tooling, and precision components. This grade targets a grit range of 4 to 8 microns, placing it in the fine super finishing range. Machinists, tool-and-die makers, and precision grinding technicians use this compound when surface finish requirements exceed what conventional abrasive stones or films can deliver.
This compound is suited for bench lapping, hand honing, and machine-assisted super finishing operations on precision parts including cutting tools, valve seats, bearing surfaces, and gauges. The orange color coding identifies the Grade 5 formulation, making it easy to distinguish from coarser or finer grades when multiple compounds are in use at the same workstation. It is appropriate for both shop and field touch-up applications where a controlled, repeatable finish is required.
Designed as an OEM-grade diamond grit compound for super finishing applications on hardened and precision-machined surfaces where a 4 to 8 micron abrasive range is specified.
Apply this compound using a clean lap, honing stick, or felt bob appropriate to the workpiece geometry. Keep Grade 5 compound tools strictly separated from coarser grades to prevent cross-contamination and unintended surface damage. Clean the workpiece and tooling thoroughly before switching between grit grades. Follow your facility's standard safe-handling procedures for abrasive compounds, including eye protection and ventilation where airborne particles may be generated.
