Metric coarse is a 60 degree metric thread form and the most common thread form machined in the UK. Hand taps are typically used in sets of 3 and have a straight flute, but can also be used as a machine tap if required. The perfect form thread is generated by a combination of effective pitch diameter, major diameter and chamfer length.
All metric coarse hand taps are available in sets or as individual taps (first/taper, second, plug/bottom hand taps). It is advisable to use all 3 taps however in lighter cutting materials, the second tap is often missed out. We stock hand taps from famous British brand PRESTO and Italian performance tap manufacturer UFS. Order online and buy today for next day delivery.
