Built from high speed steel with a coated finish, this bit features a 135-degree split point, web-thinned geometry, and a regular spiral flute for efficient chip evacuation. It carries a straight-cylindrical shank and measures 1.375 inches in overall length with a 0.500-inch flute length. At 0.040 inches in diameter (Wire Size 60), it is suited for precision work where a standard jobber-length bit would be impractical. Licensed HVAC, mechanical, and machining trades rely on this series for close-quarter drilling in metal components.\u003c\/p\u003e\n\u003cp\u003eThe R41C series is rated for high-performance applications with a primary workpiece material designation of titanium, making it appropriate for demanding metal fabrication, HVAC component drilling, and mechanical assembly where small-diameter, short-length bits are required. The 2.5xD flute-to-diameter ratio supports stability in screw machine and CNC setups. Each package contains one bit, with a minimum order quantity of 12 units. This bit meets ANSI and NAS 907 standards, confirming dimensional and material compliance for professional trade use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire Size 60 diameter at 0.040 inches for precision small-hole drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces walking and entry force\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (1.375 inches overall) for use in confined spaces and short-stroke machines\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute with 2.5xD ratio for clean chip removal\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 specifications for heavy-duty, high-performance applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw machine length drill bit compatible with standard straight-shank drill chucks used in bench drills, CNC machining centers, and hand-held drill motors that accept straight-cylindrical shanks at this diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and trade professionals using compatible drill chucks rated for straight-cylindrical shanks. Ensure the chuck and spindle are fully stopped and de-energized before changing bits. Secure the shank firmly in the chuck to the full grip depth to prevent slippage under load.
