Built from solid carbide and finished with a TiAlN coating, this bit delivers heat resistance and extended tool life in high-speed cutting environments. It features a 140-degree split point for accurate self-centering entry and reduced thrust. At 5.56 mm in diameter with an overall length of 2.5984 inches (66 mm), it is sized for short-reach, rigid setups typical of CNC machining centers and screw machine operations. Coolant-through capability supports chip evacuation and thermal management during deep-hole drilling cycles. This bit is part of the CoroDrill Delta-C R840 series and is intended for use by machinists and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for cutting steel, stainless steel, and cast iron. The 3xD flute-to-diameter ratio and 28 mm flute length make it well suited for shallow-to-moderate depth holes in production environments. Its straight-cylindrical shank at 6.00 mm diameter fits standard drill chucks and collet systems found on CNC turning centers, machining centers, and screw machines. The right-hand cutting direction and regular spiral geometry support consistent chip flow in ferrous materials across both low- and high-volume production runs.\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\u003eTiAlN coating for thermal stability and extended cutting life at elevated speeds\u003c\/li\u003e\n\u003cli\u003e140-degree standard point for accurate self-centering and reduced walking\u003c\/li\u003e\n\u003cli\u003eCoolant-through design promotes chip evacuation and controls cutting zone temperature\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eCoroDrill Delta-C R840 series rated for steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for primary workpiece materials including steel, stainless steel, and cast iron.
