How it works
Drilling forms the initial hole. Reaming can finish the size and roundness for a locating pin, while tapping adds an internal thread. Blind holes require allowance for bottom geometry and usable depth.
What to show on the drawing
Specify diameter, position from datums, through or blind condition, usable depth, thread standard and edge breaks.
Inspection
Agree on hole size, position, burr limits and suitable gauge or measurement methods.
Feasibility, tolerances and lead time are confirmed for each enquiry.
Frequently asked questions
Is drill depth the same as usable thread depth?
Not necessarily. For blind holes, specify usable thread depth and give a separate drilled-depth limit where bottom clearance matters.
