HMT Rivet Drilling Process - Step 3

  • How Rivet head should appear after it has been fully pilot drilled and then core drilled through
  • At this stage a cold chisel/hammer can be used to break the head of the rivet loose so the next stage of drilling can continue. This will enable better swarf clearance and inspection as the cut progresses.
