Goliath NPS Coventry Chaser (Dieheads) S-Rake

• 4 piece coventry style thread cutting chaser.
• Coventry Chasers (Dieheads) can be used on Turret lathes, CNC, and automatic screw machines.
• The total system is noted for its ease and simplicity in setting, and for the accuracy of cut over a very wide range of thread variations.
• Automatic self-opening at the completion of each cut makes Coventry ideal for batch or continuous production work.
• Coventry chasers are designed so that cutting takes place at the chamfer and the first full tooth. The other teeth are above centre height, so they act as a nut, ensuring accurate pitch.
• Rugged - simple construction for reliability and long life.
• Compactness - permitting use on machines with limited clearance.
• Accurate Pitch - due to the guiding action of the non-cutting portion of the die.
• Adjustability - providing fine regulation of finished diameter for 3a class threads.
• Parallel threads - due to the very efficient support of the dies in the diehead.
• Minimum downtime - for change of thread size, important for production economy on short to medium batch runs.
