Set of 6 Hardness Tester Files,HRC40 to HRC65 Precision Metal Hardness Testing Kit with Oxford Storage Bag, 7.1" Carbon Steel Files for Industrial QC, Machining & Tool Manufacturing

Ensure consistent material quality with this professional-grade 6-piece Hardness Tester File Set, engineered for industrial users who need fast, reliable, and portable metal hardness verification. Each file in this set is precision-manufactured from high-carbon steel and calibrated to a specific Rockwell C-scale hardness level—from HRC40 up to HRC65. The files are designed to scratch or resist scratching against a workpiece surface, providing a practical method for rough estimation of metal hardness without complex equipment. For ease of use, every file features a color-coded ergonomic handle, allowing technicians to instantly identify the correct hardness level during inspections or production checks. The 7.1-inch (18 cm) length offers optimal balance and control for accurate testing in tight or awkward spaces. All components come neatly packed in a durable black Oxford fabric storage bag (20×5×3 cm), protecting your investment from dust, moisture, and physical damage while ensuring portability across job sites, workshops, or quality control stations. This kit is trusted by professionals in metal manufacturing, machining, tool & die production, automotive repair, and industrial maintenance—wherever quick, on-the-spot hardness assessment matters. What’s Included:6 × Hardness Tester Files (HRC40, HRC45, HRC50, HRC55, HRC60, HRC65)1 × Oxford Cloth Storage BagReady for immediate industrial use – no assembly required.Note: This is a comparative testing tool for rough estimation only. For precise hardness measurement, use certified lab equipment.
