Built from high-speed steel (HSS) with a bright\/uncoated finish, it features a 0.161 inch diameter (Wire Size 20), a 118-degree standard point angle, and a right-hand spiral flute for efficient chip evacuation. At 2.125 inches overall length with a 1.0625-inch flute, this stub-length bit delivers increased rigidity over jobber-length bits, making it well-suited for precision drilling on automated or manual machine setups where deflection control is critical.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for use on titanium as its primary workpiece material, reflecting the high-performance designation of the R41 series. Its web-thinned, tapered web configuration reduces thrust requirements and improves penetration at entry. The straight-cylindrical shank fits standard drill chucks across a wide range of machine tools, including drill presses, CNC machining centers, lathes, and screw machines. It is appropriate for machinists, tool and die technicians, and production shop personnel working within the 0.150 to 0.200 inch diameter range under ANSI standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.161 inch diameter (Wire Size 20) with 118-degree standard point for clean entry\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction rated for titanium and general-purpose workpiece materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides superior rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with 2.5xD flute-to-diameter ratio for effective chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — compatible with a broad range of cutting fluids and lubricants\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards; R41 series high-performance designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose screw machine length drill bit for use across a range of machine tools accepting straight-cylindrical shanks, suitable for applications involving titanium and other metals within the 0.150 to 0.200 inch decimal inch size range per ANSI specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with machine tool operation. Ensure the drill chuck is fully secured and the workpiece is properly fixtured before operation. Apply appropriate cutting fluid for the workpiece material, particularly when drilling titanium, to manage heat buildup and extend tool life. Inspect the cutting edges for wear 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: 0.161 inches (Wire Size 20)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.0625 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 (HSS)\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\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\u003eSize Range\u003c\/strong\u003e: 0.150 to 0.200 inches decimal inch\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\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: 5998823\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51700494106930,"sku":"5998823","price":43.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88c6baa4565eb278ac18024d1a75922c.jpg?v=1788391074","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998823-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
