Built to DIN 6537K standards, this bit features a 140-degree split point with web thinning and a coated finish for improved wear resistance. The 7.80 mm (0.3071 inch) diameter and straight-cylindrical shank make it compatible with standard drill chucks and CNC machine tool holders. With coolant-through capability and a 3xD flute-to-diameter ratio, it is suited for high-speed, chip-clearing work in production environments. Licensed machinists, tool and die workers, and CNC operators are the primary installers.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered for cutting cast iron and steel in screw machine and short-hole drilling operations. The screw machine length body keeps the tool rigid in tight setups or where spindle clearance is limited. The spiral flute design promotes efficient chip evacuation during continuous drilling cycles. With a maximum drilling depth of 38.00 mm and a 2-flute regular spiral configuration, it handles repetitive production drilling where dimensional consistency is critical. The parallel web construction and submicron carbide grade support extended tool life in ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with submicron carbide grade for superior hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003e140-degree SU point with web thinning for accurate self-centering entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-feed drilling and extended cycle times\u003c\/li\u003e\n\u003cli\u003eCoated finish reduces friction and extends tool life in cast iron and steel\u003c\/li\u003e\n\u003cli\u003eDIN 6537K standard compliance ensures dimensional consistency for production tooling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard collets and drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers, screw machines, and drill presses equipped with standard straight-shank toolholders.
