Taps and Solid-carbide Thread Mills for Titanium

Emuge Corp. has introduced a line of tools for threading titanium alloys. The line includes taps with new geometry designs and solid-carbide thread mills. Tap sizes from No. 0 to 1 in. are available in UNC, UNF, and from 3 by 0.5 to 24 by 3.0 in metric.

This titanium program includes C-Ti and D-Ti taps with new high relief geometry (HRG) technology, which increases space between the friction surfaces for enhanced lubrication and reduced torque load in both forward and reverse direction. According to the company, HRG counteracts the high compressive forces produced by the elastic memory of titanium. An optimized flute angle and profile create tough, long chips that evacuate axially in one direction. Taps are manufactured with HSS-E steel and have a modified bottoming chamfer to reduce torque and increase tool life.

With advanced left-hand helical flute form and chamfer geometry, C-Ti taps optimize chip evacuation in the forward direction and add strength to the cutting teeth for enhanced tool life and process security. The D-Ti taps are available in STI thread sizes. Both C-Ti and D-Ti taps are available with a special NT2 coating with nitriding that provides increased edge hardness and a steam layer over the nitriding that promotes lubricity to prevent cold welding. Taps are also available with a TiCN multilayer PVD coating for increased edge hardness and surface lubricity.

The new program also offers a selection of thread mills. Threads-All Z-GF style thread mills require only eight stock standard tool sizes to produce more than 100 commonly produced screw thread designations.

They have internal coolant, multiple spiral flutes to eliminate chatter, a large cutter diameter with high profile correction to ensure true-to-gauge threads, and an extended milling portion that enables 2xD length of cut.
