Pre-tap and finishing tap
The pre-tap is marked with a ring on the shank and cuts first; the finishing tap has no marking and brings the thread to its full size. Together they cut clean threads in through holes and blind holes.
Steam-tempered steel
The taps are steel with a steam-tempered surface, which prevents the tap from cold welding to the workpiece. The shank is reinforced, so the tool stays sharp after repeated use.
How to cut a G1/4 thread
- Drill a core hole of 11.8 mm.
- Cut with the pre-tap (ring marking) first, then with the finishing tap.
- Use a tap wrench on the 9 mm square (not included), a little cutting oil, and back the tap off now and then to break the chips.
