Manufactured from high-speed steel with a coated finish, this bit carries a wire gauge size of 22, corresponding to a decimal diameter of 0.1570 inches. The 135-degree split point with web thinning reduces walking at entry and lowers the thrust force required to start and maintain a cut. At 2.125 inches overall length with a 1.0625-inch flute length, it fits standard drill chucks and screw machine setups without modification. The straight-cylindrical shank ensures consistent grip in both keyed and keyless chucks.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for right-hand cutting in screw machine length configurations, making it well suited for short-reach drilling operations on CNC lathes, automatic screw machines, drill presses, and hand-held power drills used in production and maintenance environments. The Series R41C is rated as a heavy-duty grade with a 2.5xD flute-to-diameter ratio and a tapered web configuration. The primary designated workpiece material is titanium, though the high-speed steel construction and split-point geometry also support use on a range of metals encountered in machining and fabrication work. Compliant with ANSI and NAS 907 standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 22 (0.1570 inch decimal diameter) with matching straight-cylindrical shank diameter of 0.1570 inches\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces drill walk and entry thrust\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration improves chip evacuation and cutting stability\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (2.125 inches OAL) for short-reach rigidity in tight setups\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 standards; heavy-duty drill bit grade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard production drill bit for screw machine and short-length drilling applications requiring a 0.1570-inch diameter hole.

Secure the straight-cylindrical shank firmly in a keyed or keyless chuck before operation and verify runout is within acceptable limits for the application. Always power down and de-energize the machine before changing tooling. Follow applicable shop safety standards and wear appropriate eye protection when operating rotating cutting tools.\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: 22\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1570 inches\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\u003eShank Diameter\u003c\/strong\u003e: 0.1570 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\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\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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\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: 0.11 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: 5998682\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51712699957554,"sku":"5998682","price":44.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c62017215e6d22bd7b64c85808207a7.jpg?v=1788488007","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998682-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
