According to technical analysis from RapidDirect, water jet cutting can achieve standard tolerances of ±0.002 to ±0.001 inch, with optimal precision reaching ±0.001 inch (0.025mm) under ideal conditions ^[2]. This makes it one of the most accurate cutting processes available for industrial applications.

Several factors influence achievable tolerance:

Cutting speed: Slower speeds generally produce better accuracy
Material thickness: Thicker materials may experience more taper
Material hardness: Harder materials can affect cut quality
Machine stability: Worktable vibration and rigidity matter
Nozzle condition: Worn nozzles degrade precision
5-axis capability: Taper compensation significantly improves hole accuracy ^[4]

For aerospace applications, hole tapering is a critical concern. As one manufacturing professional noted on Reddit: "We were holding +/- .005" all day. Also keep in mind, any holes will be tapered. I would normally expect this and plan to drill them out post." ^[4] This highlights the importance of understanding post-processing requirements when quoting jobs to aerospace buyers.

"Water jet can be as good as a machined surface and the tolerance can be 15 thou even if it's an old focus tube. If the machine is a 5 axis one, it can do taper compensation too." — Manufacturing Professional, r/MechanicalEngineering ^[4]
