Tolerance capabilities:- 
Holes centers +/- 0.0005" are achievable. 
Hole dimensions and depth. There are a number of variables that affect hole tolerances such as material selection/thickness part size, tabbing, production quantity and target costs. We therefor suggest contacting manufacturing in the early design stages.

Design guidelines:-
Material thickness 0.0005" to 0.1" .
Holes minimum dia. approximatly equal to plate thickness.
Minimum metal between holes approximatly equal to metal thickness.
Minimum radii, approximatly equal to plate thickness.
Sheet size upto 40"*120".
