The drills in the drill block can also be called in a format that allows one T-Code called for any number of drills in a pattern. This is binary drill coding. To call multiple drills at one time, simply add the binary numbers. For instance to call T302 and T303 together, you would add the binary numbers 2 + 4 and use T6.
The drills would be numbered like this on an 11 spindle drill:
