At 0.1935 inches in diameter and 2.25 inches overall length, this bit is built from high-speed steel (HSS) with a steam oxide finish that reduces friction and extends tool life. The 135-degree split point starts on contact without a center punch, and the web-thinned, tapered web configuration reduces cutting force. It is sized for machinists, maintenance technicians, and metal fabricators who need a short, rigid bit for precision work in tight clearances or on drill presses and screw machines.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling steel, stainless steel, cast iron, and high-temperature alloys. The screw machine length — shorter than a jobber bit — provides added rigidity and reduced deflection, making it a go-to choice for production drilling, fixture work, and any application where hole location accuracy matters. The 1.1875-inch flute length provides adequate chip clearance for typical hole depths in this size range. It conforms to ANSI and NAS 907 standards, confirming dimensional and performance compliance for specification-driven work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point self-starts on contact, no center punch required\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust and cutting force in hard metals\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating minimizes friction and helps resist heat buildup\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (2.25 inches OAL) provides superior rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute, straight cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 standards for heavy-duty, high-performance applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drilling steel, stainless steel, cast iron, and high-temperature alloys.

Ensure the shank is fully seated and the chuck is tightened before operation. Use appropriate cutting fluid or coolant when drilling stainless steel or high-temperature alloys to manage heat and extend bit life. Inspect the cutting edges for wear before each use — a dull split-point bit generates excess heat and can work-harden stainless and alloy materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1935 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1935 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 Point\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: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\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: Steel, Stainless Steel, Cast Iron, High-Temp Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R41C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: 5998597\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51723516477746,"sku":"5998597","price":53.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35555ba5c4e6cdc1318e278ecb56b899.jpg?v=1788605730","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998597-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
