Application Notes:
As to general physical dimensions, spiral point taps are identical with the standard hand tap. However, the spiral point tap has the cutting face of the first few threads cut at a predetermined angle relative to the tap's axis angle to force the evacuation of chips ahead of the cutting action. This feature, plus the excellent shearing action of the flute, make spiral pointed taps ideal for production tapping of through holes. Typically, this type of tap has a shallower flute passage than conventional taps. This gives the spiral point tap more cross-sectional area, which means greater strength, allows higher tapping speeds, and requires less power to drive. These TiN coated extension spiral point taps are made to conventional tap dimensions, except that they have an extended shank to tap hard to reach or inaccessible holes. Thread length, shank diameter, and square are made to standard specifications listed in Table 302. These extension taps are available in hand style, and in small shank style. TiN (titanium nitride) coating is wear resistant and reduces friction, aiding in cutting edge retention. It has an ideal combination of hardness, toughness, adhesion and inertness. TiN coated taps often improve their lifetime by a factor of two to ten times, depending on the material being tapped.
