Built to DIN 6539 standards, this 0.5-inch (12.70 mm shank) bit features a 140-degree split point (SU type) with web thinning for reduced thrust and faster entry. The two-flute spiral configuration with a 3xD flute-to-diameter ratio clears chips efficiently and maintains straightness through the cut. At 102 mm overall length with a 51 mm flute length, the screw machine format offers added rigidity over jobber-length alternatives. Machinists, tool-and-die technicians, and CNC operators rely on this series for consistent hole quality in production environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered for cutting cast iron and steel, making it well suited for production machining, maintenance shops, and fabrication environments where tool life and dimensional accuracy are priorities. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. The coated carbide construction supports dry and mist-lubricated drilling. Maximum drilling depth is 1.258 inches (31.95 mm). Series 1242 bits from GUHRING are positioned for high-cycle production work where consistent tolerances are required across multiple parts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with submicron carbide grade for extended cutting life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree SU split point with web thinning reduces entry thrust and self-centers without a pilot hole\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral design with parallel web configuration promotes chip evacuation and bore straightness\u003c\/li\u003e\n\u003cli\u003eScrew machine length format (102 mm overall) provides increased rigidity compared to jobber-length bits\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank (12.70 mm) fits standard chucks and collet toolholders\u003c\/li\u003e\n\u003cli\u003eCoated finish for heat and wear resistance during high-performance drilling cycles\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.007 to +0.025 mm ensures consistent fit to spec\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 6539 Series 1242 screw machine drill bit for use in CNC machining centers, drill presses, and manual lathes equipped with standard straight-shank toolholding.
