Taper tap or starting tap.This is similar to a plug tap but has a more pronounced taper to the cutting edges. This feature gives the taper tap a very gradual cutting action that is less aggressive than that of the plug tap. The number of tapered threads typically ranges from 8 to 10. A taper tap is most often used when the material to be tapped is difficult to work (e.g. alloy steel).

Intermediate tap or second tap.The tap has tapered cutting edges which assist in aligning and starting the tap into an untapped hole. The number of tapered threads typically ranges from 3 to 5. In the US they are commonly known as intermediate taps whereas in Australia and Britain they are commonly known as second taps.

In metal working the use of a tap lubricant is essential to achieve cleanly formed threads and to minimize friction. Failure to use the correct lubricant may result in ragged threads as well as a substantial increase in the amount of torque required to turn the tap possibly resulting in breakage.

Set includes metric coarse and fine sizes ranging from M3 to M12. It also come with an 11 blade metric pitch gauge so you can measure the threads your going to cut. Supplied in heavy-duty metal storage case.
