1. Adjustable Angle Block Material and treatment: quality alloy steel, heattreated to HRC5052 Precision surfaces: working faces finely ground to maintain precision with a parallelism and verticality of 0.005 mm 2. Marking Technology Markings: clear and wearresistant handwriting Finish: nickelplated appearance treatment to prevent rust 3. Precision and Positioning Angle adjustment: indicated by the dial Locking: can be securely tightened with a wrench for precise positioning, enabling various fixed angles required for processing and workpiece inspection 4. Wide Application Compatibility: suitable for milling machines, grinding machines, and drilling machines with adjustable angle gauges Use: can be used for marking or clamping workpieces after processing, such as machining inclined appearances and holes Use scenarios Scenario 1: In a milling operation, set the block to the desired angle using the dial and clamp the workpiece to drill holes at a precise inclination Scenario 2: During grinding, mark inclined surfaces and secure the workpiece for repeatable stock removal and accurate angle verification Scenario 3: In inspection, position the part at a fixed angle to verify geometry against drawings and ensure proper hole alignment
