HSS Taps

• Alpha HSS Hand Taps are precision manufactured in Europe to ISO529 standards.

Alpha TAPER Taps

Alpha Taper Taps have a lead of eight threads and are used as a starting tap in difficult
or high precision holes.

Alpha Taper taps can be identified by the single ring on the shaft near the driving square.

Alpha INTERMEDIATE Taps

Alpha Intermediate Taps have a lead of four threads and are used in most general purpose applications.

Alpha Intermediate taps can be identified by the two rings on the shaft near the driving square.

Alpha BOTTOMING Taps

Alpha Bottoming Taps have a lead of two threads and are used when tapping blind holes.
Usually preceded by a taper or intermediate tap.

Alpha bottoming taps can be identified by their plain shaft, they have no rings on the shaft
near the driving square.

Alpha Hand Taps

Alpha Hand Taps are for general purpose applications such as production tapping 
or hand tapping operations.

Taper, plug and bottoming styles provide versatility in tough materials, blind
and through holes. The most accurate holes require a taper (top), Intermediate (middle)
and a bottoming (bottom) tap to create a perfect finish.

Alpha Spiral Point Taps

Alpha Spiral Point Taps have the same general physical dimensions as standard hand taps.

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 point 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 great strength, allows higher tapping speeds, and requires less power to drive.

The spiral point taps are also referred to as gun taps.

Alpha Spiral Fluted Tap

Alpha Spiral Flute Taps feature spiral flute design rather than conventional straight flutes.

The spiral fluting feature aids in evacuating chips out of the tapped hole. Spiral flute taps
are ideal for hard materials or in blind hole where the swarf needs to be drawn out.
