Manufactured from high speed steel with a bright uncoated finish, this bit features a 0.177 inch diameter corresponding to wire size 16 and a standard 118-degree point angle. The right hand spiral flute geometry promotes efficient chip evacuation during drilling. The web-thinned, tapered web construction reduces thrust and improves cutting performance. Licensed machinists, maintenance technicians, and fabrication professionals install this bit in standard drill chucks for stub-length drilling tasks where rigidity and reduced deflection are priorities.\u003c\/p\u003e\u003cp\u003eThe PRECISION TWIST DRILL 5998801 is suited for short-hole and close-tolerance drilling applications in production and maintenance environments. Its screw machine length format — shorter than a jobber bit — improves rigidity and accuracy in drill press and CNC drilling operations. The Series R41 designation identifies this as a general purpose high speed steel bit built to ANSI standards. The straight-cylindrical shank fits standard drill chucks without adapters. This bit is listed for use on titanium as the primary workpiece material, making it appropriate for aerospace, medical, and precision fabrication work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eScrew machine length format improves rigidity and reduces deflection in short-hole applications\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides hardness and heat resistance during metal drilling\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general purpose center-finding and penetration\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces axial thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eRight hand spiral flute design promotes consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suited for use with cutting fluids on a range of metals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit for use in standard drill chucks accepting straight-cylindrical shanks, conforming to ANSI dimensional standards for wire size 16 stub-length bits.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with proper chuck torque and drilling speeds for the workpiece material. Ensure the drill press or power tool is de-energized and secured before changing bits. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life.
