Borescopes for Metal Machining

Metal machinists of automotive, aviation, hydraulic and other precision parts can inspect for internal burrs, defects, surface finish irregularities, and more, even inside deep or narrow bores. These borescope applications can be done using a Hawkeye borescope. Hawkeye Precision Borescopes allow for fast, reliable visual inspection inside complex machined parts and through very small openings that could never be seen with the naked eye… including inside fuel injector nozzles, engine blocks, transfer cases, brake manifolds, hydraulic assemblies, valve seats, and more. Below, you will find a few examples of machining borescope applications.
