The bit measures 0.0768 inches in diameter with a 140-degree drill point angle and a total overall length of 2.2440 inches. An AlCrN coating provides thermal resistance and extended tool life during high-speed operations. The right-hand cutting direction and straight-cylindrical shank conform to DIN 6535 HA standards. This bit is built for machinists and tooling professionals who require tight-tolerance, repeatable results in small-diameter drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is suited for blind hole drilling, stack drilling, and through-hole drilling across a range of workpiece materials. Primary materials include cast iron, non-ferrous metals, stainless steel, and steel. Secondary material compatibility extends to cobalt, glass, graphite, iron alloys, nickel, titanium, and titanium alloys. The 5xD flute-by-diameter ratio and 14.00 mm maximum drilling depth make it a practical choice for close-tolerance production environments where micro-diameter precision is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in micro-diameter drilling\u003c\/li\u003e\n  \u003cli\u003eAlCrN coating improves thermal stability and extends tool life in high-temperature cuts\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle reduces thrust force and improves centering accuracy\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and heat management at depth\u003c\/li\u003e\n  \u003cli\u003eDIN 6535 HA compliant straight-cylindrical shank for secure, standardized toolholder fitment\u003c\/li\u003e\n  \u003cli\u003eCompatible with blind hole, stack, and through-hole drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders accepting a 0.1180-inch (3.00 mm) straight-cylindrical shank conforming to DIN 6535 HA.
