electing air tappers
Tapping capacity chart depending on the materials
S
The tappers of
Series MAS … and MASE … P
are the best choi-
ce for tapping by hand thru-holes.
Its quick change head together with the standard tap holder
allows the tap auto-center, what means an excellent performan-
ce conditions.
The tappers of
Series MAS … B and MASE … PB
, are more
advisable for high precision tapping, in vertical position for the
straight versions, recommended to use a torque arm (see on
page 195) or by hand in a horizontal position, where are recom-
mended the pistol type versions with side handle.
In this case, the quick change head of the tappers allows fitting
two kinds of high precision tap holders for blind holes or thru-
holes, this last one with a built-in clutch which stops the tapping
when the taps reached the base of the hole and therefore avoi-
ding the tap breakage.
In this case, the
Series MAY …
offer a high power and a
demonstrated tapping capacity.
They can fit the same tap holders than MAS … and MAS … B
Series this means that they have the sufficient features to carry
out precision threads both for blind and thru-holes up to M-12 for
steel, even M-14 in materials like aluminum and bronze.
The
MAO 16 P
tapper provides a high power able to make thru-
holes with standard tap holder, up to M-16 or even M-18 in mate-
rials which are not to hard such as aluminum, iron, etc.
