INECO BRAND MACHINE TAPS
CHOOSE THE RIGHT ONE
1. BUILDING MATERIAL OF THE MALE
= DRILLABLE MATERIAL
In order for a male to be able to work in a
effective, the material it is built with
it must be harder than the one it is supposed to drill.
For this reason the material it is built with
the male is one of the first keys to choosing the tool.
The harder the construction material of the
male, the harder the steel will be
on which he will be able to work effectively,
hardness expressed by the resistance R.
R<1400 N/mm2: alloy steels
R<900 N/mm2: hard steels and cast irons
R<700 N/mm2: common steels
The range of Ineco taps includes
HSS-CO5% steel and HSS males. In case of
threads on stainless steel or high alloy steels
choice will have to fall on cobalt males, in
in the case of work on common steels, they will instead be
suitable HSS taps.
The range also includes males for
specific uses marked by a ring
colored according to the type of use.
2. LUBRICATION AND COOLING
It is essential for good performance and for
the useful life of the tool always guarantee a
adequate level of lubrication of the hole for
emulsifiable oil medium
3. COVERINGS
The main purpose of the coating is
that of improving performance
of the tool in terms of durability.
The range includes males, as well as
that with TiN coating, also
vaporized: this particular process
of vaporization of FeO in vapour
gives the tools a particular
burnished appearance, ensuring a more
long tool life
4. SPIRAL AND ITS INCLINATION
Males with type C mouthpiece, intended
so with threads in blind holes, they can
also be equipped with a spiral that
aims to promote and increase the
extraction and evacuation capacity of the
shavings resulting from processing.
Spirals with low inclinations, e.g.
15°, are suitable for males intended
to threading of materials with chips
long. 35° or 45° spirals are intended for
harder materials
5. TYPE OF ENTRY
There are two types of entrance:
- C or "correct" to choose in the case of
tapping in blind holes
- B is preferable in case of through holes and,
with some limitations, blind.
The type of entrance is always specified
in the catalogue by means of the reference to
harmonized DIN standards; in the case of a
a male with a correct mouthpiece will be obtained
for example a DIN371/C.
6. THREAD TYPE
The Ineco range includes taps for the
Most common thread types: Metric
M and MF, Whitworth, BSP as well as for
left-hand metric threads
