CUTTING TOOLS


Back Spotfacing & Counterboring Tool


BSF


turning the workpiece Counterbores Up to 2.3xd


The BSF tool back spotfaces or back counterbores in one operation without


threading line incorporates advanced high relief geometry technology to increase space between the friction surfaces for enhanced lubrication and reduced torque load in both forward and reverse direction. This new technology counteracts the high compressive forces produced by the extreme elastic memory of titanium,” said Hatch.


New Emuge C-Ti Taps with advanced left-hand helical fl ute form and chamfer geometry combine to optimize chip evacuation in the forward direction and add strength to the cutting teeth for enhanced tool life and process security. And new Emuge Spiral Flute Bottoming Taps for threading nickel alloys have also been recently introduced. These taps are designed with a 10° Variable Helix Correction, a specially ground relief geometry in the primary cutting zone, which generates smaller, tightly rolled chips to prevent chip jamming in the tap teeth during machining.


Threading demanding titanium alloys requires high-performance tools. BSF Counterbores up to 2.3xd


For stainless and alloy steel challenges, Emuge’s new Z-Taps are designed with an advanced chamfer geometry and rake/fl ute form and are coated with GLT-1, a newly developed multilayered coating that produces a consistent, controllable chip formation that is released smoothly for fast and effi cient chip removal. GLT-1 is uniquely structured with advanced heat resistance characteristics, along with an outer anti-friction layer. “For best results, high-performance tap holders should be utilized for provid- ing a rigid setup. Ideally, we recommend the use of rigid/synchronous tapping
