Hi Everyone,

I'm curious what others are doing for their TTS setup and specifically regarding drill sizes. I'm really new to this and am just looking for some setup advise.

Do you have many TTS holders holding a range of drill sizes? Or do you constantly change out drill bits?

Even just looking at supporting a small range of screws (M2.5/M3/M4/M5) it could mean a multitude of drills (a total of 16, 4 per size if you include Loose/Normal/Close Clearance and tap holes). Seems like too many to keep setup on TTS holders all the time.

Is it reasonable to only keep drills for small holes and mill out the larger ones? I've worked on a older gantry CNC before which worked well for straight cuts but circular shapes were sloppy at best at smaller resolutions. Given the Tormach's tolerances would it be reasonable to mill out holes larger than 4mm?


Thank you for your input,
Aaron
