Built from high speed steel with a coated finish, this bit features a 135-degree split point and web-thinned, tapered web construction that reduces walking and lowers thrust during entry. At 0.1695 inches in diameter (wire size #18) and 2.125 inches overall length, it fits standard straight-cylindrical chucks and operates in right-hand cut, spiral flute configuration. It is suited for machinists, toolroom techs, and production drilling operations requiring close-tolerance holes.\u003c\/p\u003e\n\u003cp\u003eThis bit is engineered for primary use on titanium workpieces and other hard, high-strength materials where a heavy-duty grade and high-performance tool classification are required. The screw machine length body — shorter than a jobber bit — improves rigidity and reduces deflection in drill press, CNC, and turret lathe applications. The R41C series follows ANSI and NAS 907 specifications, making it a fit for aerospace and precision manufacturing workflows where dimensional and material standards are enforced. It is sold individually, with a minimum order of 12 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates center-punch requirements on most metals\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction improves chip evacuation and lowers cutting resistance\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish extends tool life in abrasive and hard-metal applications\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body (2.125 inches overall, 1.0625-inch flute) maximizes rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute geometry provides positive cutting action and reliable chip clearing\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 standards for aerospace and precision production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-cylindrical chuck drill presses, CNC machining centers, and turret lathes accepting a 0.1695-inch straight shank.

Secure the workpiece firmly to prevent movement during entry. Coolant-through is not supported by this bit, so apply cutting fluid externally to the work zone when drilling hard materials.
