It measures 0.1405 inches in diameter with an overall length of 1-15\/16 inches and a flute length of 15\/16 inches. The 118-degree standard point angle suits general-purpose drilling, while the web-thinned, tapered web configuration reduces thrust force at entry. The straight-cylindrical shank seats securely in standard drill chucks. This bit is part of the Series R41 lineup and carries an ANSI designation, making it a reliable choice for machinists, maintenance technicians, and tool room professionals working with close-tolerance hole requirements.\u003c\/p\u003e\n\u003cp\u003eThe 5998852 is rated for use on titanium as the primary workpiece material, which reflects its high-performance classification within the general-purpose grade. The screw machine length format — shorter than jobber length — provides increased rigidity and reduced deflection, making it well suited for drill press work, CNC machining centers, and manual turret lathe operations where stub-length tooling is preferred. The 2.5xD flute-to-diameter ratio supports effective chip evacuation at the shorter flute length. It is sold individually but requires a minimum order quantity of 12 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.1405 inch diameter, falling within the 0.1000 to 0.1500 inch size range for wire-gauge tooling (#28 wire gauge equivalent)\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction, bright\/uncoated finish for general-purpose use\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length design increases rigidity and reduces deflection versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral, straight-cylindrical shank for compatibility with standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; Series R41 high-performance classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for screw machine length drill bit applications in the 0.1000 to 0.1500 inch decimal inch size range.

Machinists and tool room technicians should verify spindle speed and feed rate recommendations for the specific workpiece material before drilling. Ensure the work piece is securely fixtured to prevent movement during operation. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point geometry is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1405 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Gauge Size\u003c\/strong\u003e: #28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 15\/16 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, 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\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: 5998852\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51701631615282,"sku":"5998852","price":38.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/12c6a19d4767a9158b1fac504a090b71.jpg?v=1788402844","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998852-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
