Built to NAS 907 standards, it features a 135-degree split point that self-centers on contact and reduces the need for a center punch. The cobalt construction provides heat resistance during high-speed drilling into hard metals. A straw finish indicates proper heat treatment and helps with chip identification. The 12-inch overall length gives technicians and machinists access to fastener holes in confined or recessed areas that standard-length bits cannot reach.\u003c\/p\u003e\u003cp\u003eThis bit is suited for aerospace maintenance, aircraft structural work, and industrial fabrication where extended reach and precision entry are required. The 135-degree split point and web-thinned, tapered web geometry make it effective in stainless steel, high-nickel alloys, titanium, and other hard materials common in aerospace and heavy manufacturing environments. It is installed by machinists, aerospace maintenance technicians, and MRO professionals working on both production lines and field repair applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point with web-thinning for self-centering entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eCobalt tool material for heat resistance in hard-metal and high-speed drilling operations\u003c\/li\u003e\n\u003cli\u003e12-inch overall length provides extended reach into deep or confined drill locations\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without special adapters\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with 1.4375-inch flute length for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eBuilt to NAS 907 standards for aerospace-grade dimensional and performance compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct application drill bit for use in standard drill chucks accepting a 0.1040-inch straight cylindrical shank, consistent with No. 37 wire gauge sizing in aerospace and industrial drilling setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is typically installed and operated by machinists or aerospace maintenance technicians using a handheld or drill press setup with a standard chuck. Ensure the shank is fully seated and the chuck is firmly tightened before operation. Appropriate cutting fluid or lubrication is recommended when drilling hard metals to extend tool life and maintain hole quality.
