Built from high speed steel with a coated finish, this bit features a 135-degree split point and web-thinned geometry that reduces walking and cutting resistance on entry. The straight-cylindrical shank provides consistent chuck grip, and the regular spiral flute with a 2.5xD flute-to-diameter ratio promotes efficient chip evacuation. At 0.098 inches in diameter (wire size #40), it is a short-length tool intended for precision hole production where rigidity and accuracy matter. Licensed HVAC, mechanical, and industrial trades will find this bit suited to close-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThis screw machine length bit is designed for use in drill presses, CNC machining centers, and hand-held power tools where a rigid, stub-length drill is required. Its primary workpiece material rating is titanium, though the high speed steel construction and heavy-duty grade make it appropriate for a range of ferrous and non-ferrous materials in sheet metal, mechanical assembly, and component fabrication scenarios. The short overall length of 1-13\/16 inches reduces deflection in tight clearance areas. The R41C series targets high-performance production drilling environments where consistency across multiple holes is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces drill walking and lowers thrust force on entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration improves chip clearance and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 1-13\/16 inches overall for maximum rigidity\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute and 2.5xD flute ratio for reliable chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 standards for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit screw machine length drill bit for standard straight-shank drill chucks in drill presses, CNC machines, and power hand tools.

Ensure the machine spindle is at a full stop before inserting or removing the bit. Use appropriate cutting fluid when drilling titanium or hardened materials to manage heat and extend tool life. Always wear eye protection and follow applicable ANSI safety standards when operating rotary cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.098 inches (Wire Size #40)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/16 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\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\u003ePoint Type\u003c\/strong\u003e: Split Point\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\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 5998586\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51719490339122,"sku":"5998586","price":40.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4a58b727107548582f5a022f425721e.jpg?v=1788559710","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998586-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
