Measuring 0.041 inches in diameter with an overall length of 1.375 inches and a flute length of 0.5 inches, this bit operates with a 118-degree standard point angle and a web-thinned, tapered web configuration for improved penetration and reduced thrust. The bright\/uncoated finish suits general-purpose use across a range of ferrous and non-ferrous materials, including titanium. It is installed and used by machinists, tool-and-die technicians, and precision fabricators working in production or maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for screw machine length applications where a shorter body provides added rigidity and reduced deflection compared to jobber-length bits. The Series R41 designation places it within a high-performance line conforming to ANSI standards. Its compact 1.375-inch overall length makes it well suited for CNC drilling, turret lathes, screw machines, and bench drill press work where workpiece clearance or chuck depth is limited. The 2.5xD flute-to-diameter ratio supports efficient chip evacuation in short-cycle, repetitive drilling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.041-inch diameter, wire gauge size 59, for fine-tolerance drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning for reduced entry force\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for general-purpose and titanium workpieces\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body (1.375 inches overall) for added rigidity and reduced runout\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, spiral flute, straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish; no coolant-through requirement\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards; Series R41 high-performance designation\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 CNC machines, turret lathes, screw machines, and bench drill presses.

Power down all equipment before changing bits. At 0.041 inches in diameter, excessive feed pressure will cause bit breakage — use appropriate low-feed, high-speed parameters for the workpiece material. Follow applicable machine guarding and PPE requirements per shop safety standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.041 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Gauge Size\u003c\/strong\u003e: 59\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 2.5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R41\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5999301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51721518252338,"sku":"5999301","price":36.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/809ce35a00d1782adbd5645cf6f9d9f0.jpg?v=1788578446","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999301-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
