Heavy-Duty Tap Holders/Collets, CAT-V

Tension/Compression Tap Holder

This is a floating tap holder that accommodates feeding errors. Maximum pull out of .750" and compression of .370".

NOTE:

• Both tap holders use Bilz-style quick-change collet systems

• To use standard ER collets instead of quick-change collets, see adapter on page 39

• Retention knobs must be ordered separately for each holder - see pages 34-35

Heavy-Duty Rigid Tap Holder

This holder is for use on newer machine tools which have synchronous capabilities.
