Usage Notes
- Taps create threads in holes, to put bolts in
- Dies create threads on bars, to put nuts on
- Taps and Dies are brittle and fragile, do not force them
- For tapping, use lookup table to determine size of hole to drill prior to tapping (will be smaller than bolt size)
- For dies, use lookup table to determine size of the bar to use prior to threading (will be larger than die size)
- For tapping, drill appropriate hole size first with normal metal bit
- Place tap in tap wrench
- Ensure tap is perfectly lined up with hole, angle is committed from start onward and slight offset will start but then break the tap several threads in. NEVER DO THIS.
- Slowly rotate tap to begin cutting threads
- Use appropriate thread cutting lubricant for material, see reference chart
- Every 1/4 rotation of cutting, reverse tap one half rotation to break burr. If forgotten, tap will break. NEVER DO THIS. Tapping is a back-and-forth process
- If tap ever binds or requires a sudden change in force, is lined up incorrectly, possibly all the way from the start. This is unfixable. DO NOT CONTINUE or apply more force, tap will break.
- Ensure full threads are tapped by threading several full turns of the tap past the far side, if applicable.
