Thread tools \ Multi-range thread milling cutter with countersink

ATORN solid carbide thread milling cutter for female threads with 45° countersink

Application: For thread milling and countersinking in one step.
Advantages:: low power requirement and short processing time thanks to high cutting speeds and 2 processes
(countersinking and thread cutting) using one tool, very good surface quality, precise thread depth possible down
to near the base, 1 tool for right-handed and left-handed threads, for blind holes and through holes.
Process steps for thread milling cutter with countersinking step:
① Tool moves to start position centred on hole
② 90° bevel countersink
③ Begins thread milling with descending loop
④ Thread milling with subsequent ascending loop
⑤ Moves to start position and ends machining

Application: ƒ High-quality cutting material and cutting edge treatment for very high service
For producing metric right-hand threads and left-hand threads with countersink life requirements
on CNC machines in blind holes and through holes, in steel, stainless steel, ƒ Low tool costs thanks to high variability in the thread diameter, just one tool
non-ferrous metals, cast iron and special alloys material groups up to a strength required for right-hand thread and left-hand thread
of 1500 N/mm in single-part production and series production. ƒ Significantly optimised process times, as bore and countersink are produced in
2
Execution: one step
ƒ Precision-ground thread milling cutter with chamfer for maximum requirements Technical data:
in terms of process reliability and service life ƒ Suitable for thread type: M | M-L
Advantage:
ƒ Innovative cutting geometry and coating technology ensure very high degree of
dimensional accuracy, process reliability and chip removal
