• [ACCURATE RA MATCHING] Samples are matched to the arithmetical mean Ra and paired with metric equivalents in micrometers across the Ra 05 - 12.5 micrometers range, suitable for visual checks and microscope-assisted evaluation.
• [REALISTIC TEXTURE AND FEEL] Reproductions reflect the actual texture of machined surfaces so technicians and inspectors can assess finish quality by touch and sight; includes three flat grinding grades (2, 4, 8).
• [SHOP-FRIENDLY CONSTRUCTION] Lightweight and compact at about 6 x 3 x 3/8 inches, the wallet keeps samples accessible on workbenches or in tool kits and supports quick on-the-spot comparisons that with SAE specifications.
• [CHECK DIMENSIONS] PLEASE CHECK YOUR SIZE CHART RATHER THAN AMAZON'S SIZE CHART to confirm the wallet size and sample range fit your tooling, inspection fixtures and measurement workflow.
