To Inconel 625/UNS N06625/2.4856 Alloy/ASTM B443 material, Low cutting speeds, rigid tools and work piece, heavy equipment, ample coolant and positive feeds are general recommendations.
Carbide tools should have smaller angles than high-speed tools and operating speeds can be higher. A sulfur-based cutting fluid is recommended. Thoroughly clean work piece after machining to prevent surface contamination during subsequent heat treating. Chlorine additives would be an alternative.
