Surface Finish Comparator Set With 30 Specimens For Flat Lapping Reaming Grinding Turning And Milling - Pro Grade Roughness Gauges For Quick Reliable Part Inspection On The Shop Floor
✔️ 30 nickel specimens; AA roughness, ±12% accuracy
The Surface Finish Comparator Set is a pro-grade collection of 30 surface roughness specimens for quick, on-the-floor inspection of machined parts. Typical uses include flat lapping, reaming, grinding, turning, horizontal and vertical milling. Each nickel specimen measures 0.875 in × 0.375 in (22.23 mm × 9.53 mm) and shows AA roughness values to mirror real machining textures.
