GCR15 Metal ANSI Standard General Purpose HSS Hand Tap
ANSI INCH size hand thread taps set with cheaper hss hand tap for metal
the metric bottoming tap of Detail:
These are straight flute general purpose hand taps which can be used for both machine or hand tapping. They are generally the most economical tool for use on production runs, but are best on materials that produce chips, or where the swarf breaks readily. Where deep holes are to be tapped, in materials which produce stringy swarf, other types of taps may be needed, especially for coarse threads.
Hand taps can be supplied in sets of three; bottom, second and taper leads, or individually.
• Special Hi-Tungsten and Hi-Molybdenum tool
steels(9sicr material hand taps), read surface treated for maximum lubricity.
• Taper, plug and bottoming styles provide great versatility
in tough materials, both blind and through holes.
• For general use in production tapping or left hand tapping operations.
Description
TAPER TAPS have a lead of 7-10 threads at 5 degrees per side. The taper lead distributes the cutting force over a large area, and the taper shape helps the thread to start. They can therefore be used to start a thread prior to use of second or bottom leads, or for through holes.
PLUG TAPS have a lead of 3-5 threads at 8 degrees per side. They are the most popular and can be used for through holes, or blind holes where the thread does not need to go right to the bottom.
BOTTOMING TAPS have a chamfer (lead) of 1–2 threads, the angle of the lead being around 18 degrees per side. They are used to produce threads close to the bottom of blind holes.
The metric left hand thread taps of Application:
- The most common style of the 9sicr hand tap.
- Can be used by hand or for tapping under power.
- Versatile taps for use in general machine tapping or CNC tapping applications.
- Use for through hole or blind hole tapping.
