Thread production by
helical interpolation within the pitch
JEL® Thread milling cutters
In thread milling, the thread is produced by doing an helical interpolation. The cutting process
enables the production of threads from a nominal diameter of 1 mm (single profile), with
multi-profile from M2. Some tools are also equipped with countersinkers and/or face cutters.
Your PLUS:
The thread depth is equal to the drill depth if tool is not used for chamfering
Lower torque than with tapping and roll form tapping
Short milling chips avoid chip problems
High Speed Cutting (HSC) possible

drilling and thread milling in
the same operation
Maximum process reliability and
unlimited cutting speeds
JEL® PCD tools
JEL®tools with Poly-Crystalline Diamond (PCD) cutting materials, thanks to their great hardness and high abrasion resistance, are particularly suitable for the machining of light weight structured materials such as aluminium, magnesium and fibre-reinforced plastics. PCD-tipped tools increase the process reliability, since fewer radius corrections are required for circular milling in comparison to solid carbide tools, right to the end of the service life. Depending on the relevant application, this also enables an unlimited cutting speed range. The application data is determined no longer by the tool, but by the performance capability of your tool machine.

Thread production by cutting
JEL® taps
HSS-E taps can be universally used
for almost all materials. Solid
carbide taps in finest grain quality
are available for maximum tool life.
These tools are ideally suitable for
the machining of aluminium alloys
with a high silicon content, brittle
materials such as grey cast iron or
short chipping brass as well as
heavy-duty materials.
Application:
Aluminium alloys with a high
silicon content
Grey cast iron
Short chipping brass
Heavy-duty materials
Hard machining
On almost all machines
Your PLUS:
Up to 20-times longer tool life
with solid carbide taps in
comparison to taps of HSS-E
Low tool changing times due to
longer tool life
Higher cutting speeds, resulting
in shorter machining times for
workpieces
In contrast to thread cutting, no chips
are created when producing threads
with roll form taps. The thread
production is carried out by reforming.
In addition to HSS-E tools, solid carbide
roll form taps are also available,
together with roll form taps with solid
carbide stripes, exclusively from JEL®.
The combination of elastic tool body
and hard carbide edges produces
the best performance.
Applications:
Materials with elongation of > 5%
and tensile strength < 1000 N/mm2
On simple drilling machines, transfer
lines or machining centres
Also for large thread depths
Your PLUS:
Smoother surface than with
thread cutting
Up to 20-times longer tool life
in comparison to tools made of HSS-E
Small alignment errors are
compensated when using troll form taps
with carbide stripes
Higher cutting speeds possible than
with thread cutting
No chips
Deep-lying threads can also be
produced without problem
Modern CNC machines allow synchronous thread tapping without a compensating chuck, also called „rigid tapping“.
The backlash of the spindle causes stress to one side of the cut tap or form tap, respectively. This may result in a reduced tool life and lack of quality in the surface of the thread.
JEL synchro tapping chucks compensate for the length errors caused by the backlash and create the prerequisites for achieving optimum performance from your tapping tools.
TOOLS PLUS IDEAS
Your PLUS:
Optimum tool performance
Maximum tool life
Cost savings:
Can be operated with internal cooling as well as MMS 1 channel system. Only one tapping chuck therefore required (two chucks were necessary previously)
Variable drilling, countersinking thread milling system
VABOS® Tool system
VABOS® is a modular tool system which
can be used in many applications where
the use of a solid carbide tool is not
economical. This is the case if large
diameter differences have to be
overcome, such as an M10 thread with
a face countersink diameter of 32 mm.
In the production of bores and threads
on CNC machining centres, substantial
time savings and quality improvements
can be achieved.
The VABOS® tool system consists of
three components, which are designed
according to the application:
Adapter
Indexable inserts
Central tool
Central tools for VABOS® :
Thread milling cutters MKG, MGF
or TOMILL
Drill thread milling cutters BGF
or DBGF
Drills DRILLMAX or DRILLCUT
Drill reamers BRL
