Thread milling into hardened steels 45-60HRC
JEL® MGF XH Micro M1-M2.5
With the JEL® MGF XH Micro, threads can
be made into already hardened
components. This avoids complex re-
machining due to hardening distortion.
With TiAlN coating and without internal
cooling to increase stability, thread milling
is possible up to 1.5xD.
Application:
- Hardened steels between 45
and 60 HRC - Threads can be made directly
into already hardened components,
such as aviation components,
implants.... - Complex re-machining due to
hardening distortion can be avoided - Anti-clockwise cutting from M1 to M2.5
Your PLUS:
- Thread milling directly into hardened
material - Reduction in tool costs: One tool for
two processes; 90° countersinking
and thread milling with a single tool - CNC programmes can be called up
24/7 from anywhere in the world:
tpt.kometgroup.com - Multiple uses – thread milling and
90° countersinking, e.g. M1.1 and
M1.2 are made with an M1 thread
milling cutter
