Taps For Wire Thread Insert Installation
Taps for inserts installation differ from standard taps dimensionally and only Screw Thread Insert (STI) Taps are suitable for use with Wire Thread Inserts. Screw Thread Insert (STI) taps are manufactured to precise standards from either High Speed Steel (HSS) with ground threads and are available
with taper, intermediate, and bottoming leads. They have a larger diameter but the same pitch as a standard tap in order to accommodate the wire insert. Spiral point and spiral flute machine taps are also available for volume production purposes. For all sparkplug applications,pilot nose taps are recommended and are available for common metric thread sizes. The thread insert when installed into a correctly tapped hole will provide the applicable internal thread tolerance for the installed bolt.
Intermediate taps used in most general purpose applications to facilitate thread cutting true to the drilled hole.
The tap has a lead of four threads, but no size reduction.
Spiral Flute Taps
Spiral Flute taps are recommended for machine tapping for all blind hole applications, particularly in soft materials such as copper,magnesium and aluminium which produce long stringy swarf.
