ZT Forming Tap

Overwhelmingly long tool life and low torque forming tap “ZT Forming Tap”

As for the material, we have developed a new cobalt high speed steel exclusively for forming taps. By refining the material structure, hardness is improved while maintaining the toughness.

As for the geometry, a design that eliminates the margin on the thread forming chamfer has been adopted. This decreases the contact area between the tool and work material which significantly reduces wear and frictional resistance due to rubbing. The newly developed “ZT flute” is used for the oil groove shape. A deep and wide oil groove design allows for high lubrication performance.

ZT coating combines an Aluminum Titanium film with improved toughness and an ultra-smoothing polishing treatment to achieve both excellent wear resistance, heat resistance, and low friction. ZT Forming Tap is compatible with a wide range of work materials.
