1/4" UNC Recoil Tap Spiral Flute 43049
Recoil taps differ from standard taps dimensionally and only Recoil Screw Thread Insert (STI) Taps are suitable for use with Recoil Wire Thread Inserts.
Recoil taps are manufactured to precise standards from High Speed Steel (HSS) with ground threads.
They have a larger diameter, but the same pitch, as a standard tap in order to accommodate the wire insert. Spiral Flute taps are recommended for machine tapping for all blind hole applications.
