Specs
- Material: High Speed Steel (HSS)
- Type: Round adjustable die
- Thread pitch: Metric M20 x 1
- Outside diameter: one and one-half inch
- Finish: Bright, uncoated
Features
- Faces are chamfered on both sides; 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 close to a shoulder.
- Adjustment controlled by a fine pitch screw that forces the die halves apart or allows them to spring together, enabling precise start and wear compensation.
- Beveled slot design allows adjustment while the die is mounted in a machine holder; the adjusting screw can be removed with the holder engaged, enabling in-holder adjustments.
- Uncoated bright finish emphasizes geometry and reduces friction during cutting operations.
- Specifically configured for external metric threading on cylindrical workpieces with a robust outer diameter to support stable thread formation.
