Our Metric H.S.G.T. Taper Taps are a high-speed steel ground metric coarse straight flute full size taps used as machine taps or by hand for tapping in free cutting Steel up to 800N/mm2. They are an uncoated general purpose tap made to ISO 529 dimensions. These taps are right hand thread with a taper thread.
These taps require a pre-drilled hole into the steel. An M12 metric course thread requires a 10.2mm drill hole. We would recommend our W121-102 10.2mm HSS-G Ground Point Twist Drills for use with this tap.
