Adjustable Angle Block Precise gauge block with an adjustable angle from 0 to 60 degrees. Enables establishing fixed angles for workpiece detection and alignment in milling, inspection, and fixture setups. Marking Technology Clear, legible handwriting that resists wear, ensuring longterm readability for part identification and setup notes. Nickelplated Treatment Nickel plating provides corrosion resistance and enhanced durability in harsh workshop environments. Alloy Steel Construction Made from alloy steel and heattreated to hardness HRC 5052. Faces are finely ground to 0.005 mm parallelism and verticality (perpendicularity) between the working faces, delivering reliable reference surfaces. Applications Milling and CNC setup: use to establish and lock precise angles for machining features and inspection checks. Workholding and fixture alignment: align components in jigs and fixtures for repeatable orientation. Assembly and quality control: transfer and verify angle references during assembly or QC checks.
