Multi-point inserts – productive, economic

threading in mass production

Multi-point inserts are similar to full pro le-, but have more than

one insert point (two pointed inserts give double productivity, three

pointed insert give triple etc.) Stable conditions are needed due to

increased cutting forces as the cutting edge has a longer contact

length.

Considerations should be made for thread turning and thread mill-

ing:

Milling

• Completes the thread in one revolution, when using solid carbide

thread mills.

Turning

• Requires fewer passes, giving better tool life, productivity and

lower tool costs.

• Requires longer passes beyond the workpiece thread to accomo-

date the extra points.

Productivity

Thread turning with multi-point inserts

requires longer passes beyond the

workpiece.
