SPIRAL POINTED FRACTIONAL TAPS
These taps are primarily designed for tapping through holes, however, they can also be used in blind holes which are deep enough to allow for chip accumulation
in the bottom of the hole. The spiral point forces the chips ahead of the tap, thereby preventing clogging and recutting of chips. Long holes, in excess of 1-1/2
diameters, can be tapped as a result. They can be used by hand or under power and are suitable for tapping most materials, especially those with high ductility. A
variety of surface treatments are available to improve performance.

SPIRAL POINTED +.005 OVERSIZE FRACTIONAL TAPS
These taps will produce threads with a pitch diameter which is .005 larger than the basic pitch diameter. They are used primarily where the
part will be plated or heat treated after tapping or where loss of size, for any reason, is anticipated. The spiral point forces the chips ahead of
the tap, thereby preventing clogging and recutting of chips. Long holes, in excess of 1-1/2 diameters, can be tapped as a result. They can be
used by hand or under power and are suitable for tapping most materials, especially those with high ductility. A variety of surface treatments
are available to improve performance.
