J71009-99 is a high-precision aerospace-grade reamer, engineered to AS9100D quality standards and FAA/EASA MRO regulations, designed for finishing critical holes in aircraft structural components, engine casings, and hydraulic line brackets during repair and manufacturing.

Crafted from solid carbide with a TiCN coating for superior wear resistance and heat dissipation, it features a 8.0mm cutting diameter, 10mm straight shank (compatible with standard aviation tool holders), and a 6-flute spiral design for chip evacuation and surface smoothness. The reamer delivers tight tolerances (class H7), ensuring precise hole sizing for secure fastener fitment in hard alloys like titanium and Inconel. Weighing 0.15kg and measuring 120mm in length, it complies with aerospace machining specs, minimizes rework, preserves airframe integrity, and boosts MRO efficiency for commercial airline fleets.
