which tap to use
Posted: Tue Feb 26, 2019 5:50 pm
I need to re-tap a hole in EPO415 (Rolls Royce Armoured car) for an M3x10CSK. When I search on the net I find that there are coarse, fine and extra fine taps available. Which do I need?
99% it's a metric course thread. To be sure though how about asking Armortek.
