Small Threads Formed without Burrs

IT-TAflet

Thread entries and exits without burrs - made
possible by the special patent chamfer of our IT
forming tap

IT-Taflet

Technical Features

• IT-Taflet forming taps have a unique chamfer section with
reduced full profile threads (Picture 1.1).

• Unlike common forming taps
the pitch between all chamfer threads is constant.
All threads have symmetricprofile.
These features eliminate axial forces on the workpiece (Picture 2.1).

• The thread root is designed to create a rounded thread crest on the
formed thread (Picture 2.2).

Advantages in Production

• Tool life is dramatically increased because of the reduced forming torque

• Burrs at the entry and exit of holes are nearly completely avoided
due to the largely reduced axial forces.

• IT-Taflet may be used on thin work pieces as well as
on very small threads down to S0.5 due to the low torque generated.

Available in 3 executions :

• MICRO – S0.5 ~ S0.9
• MINI – M1 ~ M1.8
• STANDARD – from size M2

Available sizes

• IT-Taflets are also available in sizes from S0.5. These are used for manufacturing miniature screw threads in eye wear, watches, optical instruments, measuringinstruments and similar products requiring very small size threads of highest precision.

• The application of miniature IT-Taflets requires spindle speeds of 3’000 rpm. Both executions TiCN and C-Coat are suitable for these speeds and should be chosen according to the work material.

• For tapping at speeds below 1’000 rpm – as may be required on automatic machines – TANOI offers a special steam oxide treatment (OX).
