Application: Advantage:
For producing metric right-hand and le -hand  Innovative cutting geometry and coating tech-
threads on CNC machines in through holes and blind nology ensure very high degree of dimensional
holes in the hardened steel material group up to a accuracy, process reliability and chip removal d1
strength of 63HRC.  Thread milling cutting of very small threads from l2
Execution: M1.4 x 0.3 possible l1
 Thread milling cutters with short thread section Notes:
The tool must be used in an anti-clockwise direction!

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 le -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
