Built to DIN 6537K standards, it features a 140-degree point angle for aggressive entry and reduced thrust, a multilayer TiAlN coating with a TiN tip for extended tool life, and a right-hand spiral flute geometry. The 16 mm diameter bit has an overall length of 4.5276 inches (115 mm) and a maximum drilling depth of 1.7717 inches (45 mm), making it suited for production and precision drilling applications where a rigid, compact tool is required. Installation and operation are performed by machinists and CNC operators.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in CNC machining centers, manual drill presses, and screw machine operations where a stub-length tool is preferred for rigidity and reduced deflection. The straight cylindrical shank accommodates standard collet chucks and drill holders. The 3xD flute-to-diameter ratio and regular spiral flute design facilitate chip evacuation in short-depth drilling cycles. It is well-suited for production environments requiring consistent hole tolerances in steel, cast iron, and similar workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding materials\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating with TiN tip for extended tool life and heat resistance\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces thrust and improves entry accuracy\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification ensures dimensional consistency and interchangeability\u003c\/li\u003e\n\u003cli\u003eStub length design increases rigidity and minimizes deflection in short-depth holes\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies tooling setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production drill bit for use in standard straight-shank collet chucks and drill holders accepting a 16 mm shank diameter, per Series B041A-CPG specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified machinists following standard toolroom practices. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify runout after chucking to maintain hole tolerance.
