The Large Bore Protractor is a precision measurement instrument used for angular positioning and alignment of large-diameter bores in equipment maintenance, machining, and assembly tasks. This tool features an extended arm reach and a marked scale, allowing technicians to align components or fixtures within large bores with a high degree of accuracy. It supports use in both horizontal and vertical setups, providing stable reference points for cutting, drilling, or fitting operations that require strict angular tolerances.Attributes:• Provides accurate angle reference during alignment tasks.• Clear graduated scale ensures easy angle reading.• Portable tool suitable for field and workshop use.Applications: The Large Bore Protractor supports accurate angle measurement and alignment within large-diameter bores during setup and maintenance tasks, allowing technicians to verify or adjust angular positions to required tolerances.
