Features:

HSS-Co (Cobalt) Bright Finish UNC Spiral Flute Machine Tap.
HSS-Co Spiral Flute Taps.
Spiral Flute taps are designed primarily for machine tapping of blind holes.
They are used to the best advantage in materials that produce long continuous chips.
The right-hand spiral forces the swarf out of the hole and prevents the chips from clogging at the bottom of the hole or in the flutes, which could cause tap breakage or spoiled threads.
The Unified National Coarse thread form was introduced in 1948 as an attempt to standardise thread forms in the USA, Canada and the UK.
The thread profile of UNC is the same as for metric threads and is described in the JIS B0206 standard.
The thread is described by its major diameter and the number of threads per inch of length (TPI).
This thread series is commonly used in the mass production of bolts, screws, and nuts.
It is used for threading into lower tensile strength materials (bronze, brass, aluminium and plastics) to obtain the best resistance to stripping of the internal thread.
It is also used on quick assembly or disassembly or if corrosion or slight damage is possible.
Manufactured from HSS-Co5.
