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-pro le) can be used for different pitches

• Low cutting forces make CoroMill 327 and CoroMill 328 the

 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
