It features a 135-degree split-point tip that reduces walking on entry and lowers thrust force, making it well suited for hard, work-hardening materials. The fast-spiral flute geometry promotes chip evacuation in deeper holes. The web-thinned, tapered web construction keeps cutting forces manageable while maintaining rigidity. This bit is intended for use by machinists, maintenance technicians, and fabricators working on production or field drilling applications where standard HSS tooling falls short.\u003c\/p\u003e\u003cp\u003eThe C15930 is rated for superalloy workpiece materials, making it appropriate for aerospace, defense, and heavy industrial maintenance work where nickel-based alloys, stainless steels, and similar difficult materials are common. The straight-cylindrical shank fits standard drill chucks without adapters. With a 3.25-inch overall length and 1-1\/16-inch flute length, it is sized for typical jobber-reach applications. The right-hand cutting direction is compatible with standard drill press, CNC, and hand-tool spindle rotation. Series 3780 identifies the product family within CLEVELAND's heavy-duty cobalt line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for cutting superalloys and hard ferrous materials\u003c\/li\u003e\n\u003cli\u003e135-degree split-point reduces drill walking and lowers entry thrust\u003c\/li\u003e\n\u003cli\u003eOxide coating improves heat dissipation and surface lubricity\u003c\/li\u003e\n\u003cli\u003eFast-spiral flute promotes chip clearing in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces cutting resistance without sacrificing bit strength\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B94.11M and NAS specification designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length replacement drill bit for use with standard drill chucks accepting a 0.1695-inch straight-cylindrical shank, suitable for drill presses, CNC machines, and power hand tools in heavy-duty metalworking applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians using standard drill press or hand-tool equipment. Secure the shank fully in the chuck and verify concentricity before drilling. Always wear appropriate eye protection and secure the workpiece before starting the spindle.
