About GaugeGrade

GaugeGrade reviews precision tools — borescopes and inspection cameras, torque wrenches and screwdrivers, and aviation-grade fastening gear — and recommends the ones worth your money.

Who writes these reviews

SK spent two decades maintaining and inspecting multiple fighter-aircraft variants for the Indian Air Force, with formal qualifications in aeronautical engineering (BAMEC) and aviation fuels & lubricants. GaugeGrade applies the same inspection and torque standards he used on the flight line to the tools everyday mechanics, DIYers and trades actually buy.

That background matters here. Inspecting a turbine with a borescope, torquing a flight-critical fastener to spec, and safety-wiring a fitting so it cannot back out are things done to an unforgiving standard. GaugeGrade brings that same standard to tools ordinary mechanics, DIYers and trades actually buy.
