Sized at 31\/64 inch (0.4844 inch decimal) in diameter with an overall length of 3-11\/16 inches and a flute length of 2-3\/16 inches, this bit is built for stub-length applications that demand rigidity and reduced deflection. The 135-degree split point promotes fast penetration and self-centering without a center punch. Right-hand cut with a straight cylindrical shank, it is part of the M40CO heavy-duty series rated to ANSI standards. Machinists, tool-and-die technicians, and maintenance professionals install this bit in drill presses, CNC machines, and hand-held power drills.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production and maintenance drilling in hard ferrous metals, stainless steel, high-nickel alloys, and other tough workpiece materials where heat buildup shortens tool life. The screw machine length geometry provides extra stiffness compared to jobber-length bits, making it a practical choice for short-reach holes in tight setups or fixture work. The M40CO cobalt material grade retains hardness at elevated cutting temperatures, extending service intervals in high-cycle drilling operations. It is sold individually and is appropriate for both shop floor and field maintenance use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction (M40CO material grade) for high-heat resistance in hard-material drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eScrew machine length design provides superior rigidity and minimizes bit deflection\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with straight cylindrical shank for broad chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; rated heavy duty for high-performance production use\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 use in drill presses, CNC drilling stations, and standard chucks accepting a 0.4844-inch straight cylindrical shank.

Secure the shank fully in the chuck and verify runout before beginning a cut. Use appropriate cutting fluid or coolant when drilling hard metals to manage heat, even though this bit does not support coolant-through delivery. 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 Size\u003c\/strong\u003e: 31\/64 inch (0.4844 inch decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4844 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: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M40CO\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\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: Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 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: 5995964\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51694540914994,"sku":"5995964","price":36.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0fc5f6262074872d44705f45fbae1b7_c65a5383-7f03-4601-a8c4-b379a32ab6fa.jpg?v=1788325256","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995964-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
