Nickelplated surface for corrosion resistance and durability. Made of alloy steel with surface hardened to HRC 5052. The parallelism and perpendicularity between the working faces are finely ground to 0.005 mm, delivering reliable accuracy in every setup. Angle adjustment and fixing for precise, repeatable results. The tilt is indicated by a dial; set the desired angle and tighten with a convenient wrench to lock it in place. This allows you to establish a variety of fixed angles required for processing and detecting the workpiece. Key benefits precision: 0.005 mm parallelism/perpendicularity between working faces ensures accurate angle setup. Durable construction: alloy steel with hardening to HRC 5052 and nickel plating for longlasting use. Easy operation: dialdriven angle adjustment with quick wrench locking for fast, repeatable setups. Stable performance: reliable fixedangle reference for consistent processing and inspection. Compatible applications and scenarios Milling and drilling operations that require precise fixed angles, such as bevels, miters, or reference angles. Angle checking and fixture setup to verify workpiece geometry during inspection or QA. Fixture alignment and reference angle establishment in machining setups to ensure tool and workpiece alignment. Material and performance notes Material: alloy steel Surface treatment: nickelplated Hardness: HRC 5052 Precision: 0.005 mm for parallelism and verticality between working faces Adjustment: dialindicated tilt with wrenchlock mechanism for secure operation
