Description: Product name: Hardness Tester File Set Feature: This HRC40-HRC65 hardness file set is specially designed for on-site rapid material hardness testing. It includes 6 files of different hardness levels, with color-coded handles for distinction. The files are equipped with carbon steel wear-resistant tips and anti-slip handles, making the usage simple and intuitive. It is suitable for testing various materials such as molds, steel, and metals. An Oxford cloth storage bag is included for convenient carrying and storage. It is an efficient and practical tool for workshops, maintenance, DIY crafts, etc. Package includes: 6Pcs/Set HRC40-HRC65 Hardness Tester File Set Notice : Please allow slight size errors due to manual measurement, thank you for your understanding. Due to differences in monitors, there may be some color differences. Thank you for your understanding. For example: Start using the material with the highest hardness, such as HRC65 (black), which can be filed. Then switch to HRC60 (blue) if it can still be filed; continue to switch to HRC50 (lake green) if it can still be filed. If the file becomes slippery, it indicates that the hardness of the tested workpiece is between HRC50 and 55

• Full & Precise Hardness Range: 6 files fully cover HRC40, HRC45, HRC50, HRC55, HRC60, HRC65, ideal for on-site hardness testing of most industrial metals, steels, molds and materials
• Color-Coded Handles for Easy Identification: Color-coded handles correspond to each hardness: Red HRC40, Yellow HRC45, Light Green HRC50, Dark Green HRC55, Blue HRC60, Black HRC65. Clear markings prevent mix-ups
• Durable Material & Comfortable Grip: These hardness tester files are made of carbon steel for stable hardness and wear resistance. Curved fine teeth fit corners and curved surfaces. Knurled body with non-slip soft grip for comfortable, secure hold. Each file length: 7.1 in (18 cm)
• Usage: Gently press the hardness test file against the workpiece and file forward about 5mm; if it slips, the workpiece hardness is higher than the file; conversely, if there is a feeling of filing, the workpiece hardness is lower. It is recommended to start testing from the highest hardness HRC65 and go downward, which protects the files, extends their service life, and quickly and accurately identifies the hardness range for more precise results
• Portable Set with Convenient Storage: Complete set includes 6 hardness files + black Oxford cloth storage bag with strap, easy to carry and store for on-site and daily use
