It features a 135-degree split point angle with web thinning for reduced thrust and faster engagement on hard materials. An oxide and bronze coating provides lubricity and mild heat resistance during drilling operations. The straight-cylindrical shank measures 0.1910 inches in diameter and seats securely in standard drill chucks. With an overall length of 3.5 inches and a 1.1875-inch flute length, this bit suits close-tolerance drilling tasks across metal fabrication and maintenance applications. Two regular spiral flutes evacuate chips efficiently in right-hand cutting direction.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for use in steel, stainless steel, cast iron, non-ferrous metal, superalloys, titanium, and other hard materials. It is a general-purpose tool suited to manual drill presses, CNC drilling centers, and hand-held pneumatic or electric drills in machine shops, fabrication facilities, and industrial maintenance environments. The NAS 907 specification designation confirms dimensional and material standards compliance appropriate for aerospace and precision manufacturing work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge No. 11 size — 0.1910 inches decimal diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces walking and lowers required thrust\u003c\/li\u003e\n\u003cli\u003eOxide and bronze coating improves lubricity and extends tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles steel, stainless steel, cast iron, and superalloys\u003c\/li\u003e\n\u003cli\u003eNAS 907 specification compliance for dimensional accuracy in precision applications\u003c\/li\u003e\n\u003cli\u003eRegular spiral, two-flute design promotes efficient chip evacuation during through-hole drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-shank drill chucks across drill presses, CNC machining centers, and handheld power drills.
