US Pro Tools 52Pc Metric Tap & And Die Engineers Finishing Set US0859

US PRO need we say more.,

A Precision machined, alloy steel taps and die finishing set to leave the rest for dead!

This set of US PRO tap and dies have been produced for the engineer who wants to a job 100%. Each size comes with 3 different finishing type of taps. A taper tap, an intermediate tap and a bottoming tap in all sizes.

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.

Bottoming tap or plug tap. The tap has a continuous cutting edge with almost no taper with between 1 and 1.5 threads of taper is typical. This feature enables a bottoming tap to cut threads to the bottom of a blind hole. A bottoming tap is usually used to cut threads in a hole that has already been partially threaded using one of the more tapered types of tap. The tapered end ("tap chamfer") of a bottoming tap is too short to successfully start into an unthreaded hole. In the US they are commonly known as bottoming taps, but in Australia and Britain they are also known as plug 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.

We haven't seen any kit like this out on the market. Usually you only receive two taps per size but here you will finish the job to precision every time.

The set includes many tools to be used with the taps and die's including a tap wrench as well as a T- type tap wrench, a steel die handle with knurled screws, a screw pitch gauge, screwdriver, centre punch, 5 screw spiral extractors and 8 drills bits all set out neatly in a specially named metal carry case.
