Built from high speed steel with a coated finish, this bit measures 0.377 inches in diameter with a 135-degree split point and a web-thinned, tapered web configuration that reduces walking and cutting resistance at entry. The straight-cylindrical shank seats securely in standard drill chucks. At 3.25 inches overall length with a 1.875-inch flute length and a 2.5xD flute-to-diameter ratio, the screw machine format keeps the bit rigid and suited for close-clearance work. It is rated Heavy Duty and meets ANSI and NAS 907 specifications.\u003c\/p\u003e\u003cp\u003eThis drill bit is built for cutting titanium as its primary workpiece material, making it appropriate for aerospace, precision machining, and metal fabrication environments where titanium alloys are regularly encountered. The right-hand cut spiral flute handles chip evacuation efficiently in these tough materials. Machinists, tool and die technicians, and maintenance mechanics working with titanium or similarly hard metals will find this bit sized at letter V for direct replacement in existing setups running that designation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.377-inch diameter, letter V sizing for direct drop-in use\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces thrust force and prevents walking on hard metals\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n\u003cli\u003eScrew machine length format provides added rigidity in tight setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cut spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and NAS 907 standards for dimensional and performance compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and direct-fit screw machine length drill bit for applications requiring a letter V diameter bit in Series R42C, sized for use in standard straight-shank drill chucks and compatible with setups working in the 0.3500 to 0.4000 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachinists and tool technicians should ensure the drill press, lathe, or handheld drill is powered down and fully stopped before changing bits. Seat the straight-cylindrical shank fully into the chuck and tighten securely before use. When drilling titanium or other hard metals, use appropriate cutting fluid and avoid excessive feed rates that can generate heat buildup and reduce tool life. Dispose of worn bits in accordance with applicable shop safety protocols.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3770 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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 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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 2.5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: High Performance\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: R42C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.3500 to 0.4000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.46 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5999047\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51698965971250,"sku":"5999047","price":21.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02bcf6e9ccdc2fed46fc3701c8d3dd2b.jpg?v=1788370467","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999047-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
