tap good bill for the price. we appreciate the presence of 3 tap for finishing. the filieres not tight fit in the box but by twisting the legs should go ca I have tapped the M12 in the steel and cast iron without bp. (Although use of cutting oil at the same time) it lacks the ratchet turns left into the box (bought aside) Think also buy special drill to the initial holes to facilitate the tapping very good value
