Features

High Speed Steel construction provides longer wear life during repeated threading operations on round stock.

Adjustable mechanism enables precise control of thread depth and allows compensation for stock shoulder proximity without swapping dies.

Double chamfer design improves thread start and entry, reducing insertion effort and chatter.

Beveled slot design supports quick setup with a machine holder and streamlines adjustments via the holder’s screws.

Uncoated bright finish offers clear visibility of cutting edges during inspection and maintenance.

Ideal for metalworking tasks performed on a bench or with equipment such as a lathe, drill press, or milling setup to produce external threads on round stock.
