Built from solid carbide with a proprietary EgiAs multi-layer coating, it delivers extended tool life and heat resistance in demanding production environments. The 140-degree point angle and R-thinned web reduce entry force and improve centering accuracy. At 115.00 mm (4.5276 inches) overall length with a 65.00 mm flute length, this stub-length bit is well suited for rigid setups where minimal overhang matters. It is installed and operated by machinists and tool-and-die professionals on CNC machining centers and drill presses.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered for production machining applications where tight tolerances and tool consistency are critical. The 3xD flute-to-diameter ratio supports chip evacuation in short-hole drilling operations. Primary workpiece materials include steel and cast iron, making it a direct fit for general metalworking, automotive component machining, and fabrication shops running high-volume programs. The straight cylindrical shank seats cleanly in standard drill chucks and collet holders sized for the 16.00 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003eEgiAs proprietary multi-layer coating reduces friction and extends cutting life\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with R-thinned web improves self-centering and reduces thrust\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length minimizes deflection in high-feed production drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral flute for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.007 to +0.025 mm supports close-tolerance hole requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and multi-spindle machines accepting a straight cylindrical shank with a 16.00 mm shank diameter.
