| High Speed Ground
Thread Taps |
The taps in this catalog are all made by Threadwell
of the finest high speed steel available. They are heat treated
under controlled conditions and with the latest techniques. The
result is the finest line of ground thread taps to be found on
the market. And every tap has a built-in resistance to heat and
abrasion. On occasion, however, some of our customers have an
unusual application which requires a special surface treatment
of the tap. To give our customers the kind of service they have
come to expect, Threadwell can provide a variety of surface treatments
