Features

Round adjustable die with chamfers on both faces; one side provides a 2 to 3 thread chamfer for threading, the opposite side provides a 1 to 1-1/2 thread chamfer for threading near a shoulder.

Adjustment via a fine pitch screw that forces the die halves apart to start a thread or brings them together for finishing a cut.

Beveled slot design allows removal of the adjusting screw when the die is mounted in a holder, enabling adjustment using the holder’s screws.

HSS construction offers improved wear life for repeated left-hand threading operations on metal workpieces.

Designed for applications requiring left-hand threads directly on round stock or shafts; suitable for production and repair tasks where left-hand rotation is required.
