Sutton M2020200 M2 x 0.4 Metric Coarse Bottoming Hand Tap - Straight Flute, TCA

The Sutton M202 is a metric coarse (ISO) bottoming hand tap in 24 sizes, M2 to M36, with a straight flute and a square shank, made from Tungsten Chrome Alloy (TCA), sold singly. A bottoming tap offers a continuous cutting edge with almost no taper and is usually used to cut threads to the bottom of a blind hole.

The square shank is designed for hard threading work in a variety of materials. Carbon taps are not suitable for precision, safety or critical threads. They are for general purpose and DIY use only. The straight flutes are designed for tapping into materials where chips break up readily and present no disposal problems, particularly in through-hole tapping. Straight flute taps are only suitable for hand operations, tapping up to 1-1/2 x diameter.
