1st/ Taper Taps
Taper tap, also known as, ‘starter taps’ or ,’1st taps’, have a longer/ larger champfered end to ease the forming tool through the pre drilled hole. The taper is so to ease a tap better into an untapped hole. eg. Using a bottoming tap 1st would damage the first threads and possibly the thread at the start of the hole.
2nd/ Intermediate Taps
2nd taps are intermediate taps which assist in aligning and starting of the tap into an untapped hole. The number of tapered threads typically ranges from 3 to 5.
3rd/ Bottoming Taps
A bottoming, or, ‘plug’, tap has no tapered, front edge. Instead it’s tip is ground to a cutting edge meaning that it can create a thread to the bottom of a blind hole.
Metric Threads
Metric Coarse threads are in Millimetre (mm/ 1000ths of a metre) units and were developed to simplify the imperial systems. Europe moved to this system but the Americans chooseImperialas their default. Acoarsethreadhaslesshelical coils per mm and a metric fine threads has more.A Coarse thread (most common/ standard thread)is used forheavierloads andfineis used forlighterloads prone tovibrations.
