It reads a full 360 degrees with an accuracy of 5 minutes of arc and features a dial graduation of 0-90-0, giving technicians a clear, repeatable reading across the full measurement range. The protractor accepts three interchangeable blade lengths of 6, 8, and 12 inches, allowing it to handle a wide variety of workpiece sizes. The body and blade are constructed from stainless steel for corrosion resistance and long service life. An acute angle attachment is included in the package.\u003c\/p\u003e\n\u003cp\u003eThis bevel protractor is suited for metalworking shops, tool rooms, and precision layout environments where reliable angle measurement is required. It is commonly used by machinists, tool and die makers, welders, and sheet metal fabricators when setting up cuts, verifying joint angles, or laying out complex geometry on workpieces. The three included blade lengths make it adaptable to both small parts and larger structural measurements without the need for additional tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFull 360-degree measurement range for complete angular coverage\u003c\/li\u003e\n  \u003cli\u003eAccuracy to 5 minutes of arc for precision layout and inspection\u003c\/li\u003e\n  \u003cli\u003eDial graduation of 0-90-0 for straightforward reading in any quadrant\u003c\/li\u003e\n  \u003cli\u003eThree blade lengths included: 6 inches, 8 inches, and 12 inches\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction for durability and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eAcute angle attachment included for measuring inside angles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose bevel protractor for use in precision machining, fabrication, and layout applications requiring angular measurement up to 360 degrees.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument requires no installation. Before use, verify the blade is fully seated and locked to prevent measurement error. Keep the contact surfaces clean and free of burrs or chips that could affect accuracy.
