Most standard drills can cut at a maximum 8x as deep as their diameter

Reamers

We ream holes with diameters between 0.0585in - 0.5000in. Diameters above 0.5in will be
interpolated and checked with a bore mic. Reamers progress in 5 tenths increments (0.0005")

Thread Mills

We threadmill most threaded features to a maximum depth of 3xD. The majority of our tooling is for metric threads.
We will single-point thread mill UNC, UNF and NPT threads if needed.
