Manufactured from high speed steel with a coated finish, this bit measures 0.0785 inches in diameter and features a 135-degree split point for accurate starting and reduced walking on entry. The web-thinned, tapered web construction lowers thrust requirements and extends tool life. Series R41C designation indicates a heavy-duty, ANSI-compliant build suited for machinists, pipefitters, and production drilling applications where short-length rigidity is required.\u003c\/p\u003e\n\u003cp\u003eThis screw machine length bit is sized for compact drilling setups where a jobber-length bit would introduce flex or chatter. The 0.0785-inch decimal diameter corresponds to wire gauge size 47, making it suitable for tap drilling, clearance holes, and precision hole work in titanium and similarly demanding workpiece materials. The straight-cylindrical shank fits standard drill chucks without modification. Its 2.5xD flute-to-diameter ratio provides adequate chip evacuation for short, controlled cuts. Licensed machinists, tool-and-die professionals, and maintenance mechanics are the primary installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0785-inch diameter, wire gauge size 47 for precision hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walking and lowers entry thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web construction improves chip clearance and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides added rigidity in tight or shallow-clearance applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, spiral flute, straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 standards; heavy-duty grade for production environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in titanium as the primary workpiece material; ANSI and NAS 907 compliant, making it suitable for aerospace and industrial production drilling where those specifications are required.

Secure the workpiece firmly before drilling to prevent movement under cutting load. For titanium and other hard materials, use appropriate cutting fluid to manage heat buildup and extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0785 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Gauge Size\u003c\/strong\u003e: 47\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\u003eOverall Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11\/16 inches\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R41C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 5998610\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51700410286386,"sku":"5998610","price":38.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b0b8cd3b4a2080f7a660c9a517e57a69.jpg?v=1788389995","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998610-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
