CoroMill® 327 and CoroMill® 328 –
Single-point threading
CoroMill tools offer many advantages for thread milling. For single-
point threading, use CoroMill 327 and CoroMill 328.
These versatile tools have different diameters and pitches, and are
designed for non-rotating components:
• Same inserts (V-profi le) can be used for different pitches
• Low cutting forces make CoroMill 327 and CoroMill 328 the
fi rst choice for internal, medium to large threads and also when
stability is bad, such as milling threads in long overhangs and in
thin-walled components
• CoroMill 328 offers indexable cutting edges for productive, cost-
effective machining
• Can be used in low-power machines
• First choice for large, threads on asymmetric components
• For small batch sizes and mixed production
• No risk for conical threads caused by bending
• High productivity due to many teeth
• One grade for both tools (GC1025) covers all ISO material types
