It measures 5\/16 inch (0.3125 inch decimal) in diameter with a 140-degree self-centering point that reduces walking on entry and improves hole location accuracy. The TiAlN coating extends tool life by increasing heat and wear resistance at elevated cutting temperatures. At 4.6406 inches overall length with a 2.5156-inch flute length, this bit fits standard jobber-length applications handled by machinists, tool and die workers, and maintenance technicians working in metal fabrication and industrial settings.\u003c\/p\u003e\u003cp\u003eThis drill bit is built for drilling steel and similar primary workpiece materials in general-purpose machining environments. It is suited for CNC machining centers, drill presses, and manual drilling operations where consistent hole quality and tool longevity matter. The coolant-through design supports internal coolant delivery, making it compatible with coolant-fed spindles and toolholders. Its 8xD flute-to-diameter ratio and regular spiral type make it a practical choice for production drilling where chip evacuation and cutting stability are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in steel drilling applications\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for extended tool life under high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003e140-degree self-centering point reduces drill walk and improves entry accuracy\u003c\/li\u003e\n\u003cli\u003eCoolant-through design compatible with internal coolant delivery systems\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eR-thinned web with tapered web configuration reduces thrust and improves penetration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard jobber-length drill applications targeting steel as the primary workpiece material.

Ensure the chuck or collet is properly torqued to the toolholder manufacturer's specification before operation. When using the coolant-through feature, verify that coolant pressure and flow are within the spindle system's rated parameters before starting a cut. Inspect the cutting edges for wear or chipping before each use and replace the bit if edge integrity is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.6406 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.5156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Self Centering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eDiameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DH418\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.5156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: YG-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DTX418020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YG-1","offers":[{"title":"Default Title","offer_id":67909743542578,"sku":"DTX418020","price":213.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8ac2196c53e00440c14a2f09e4e379e7.jpg?v=1791191000","url":"https:\/\/voomisupply.com\/products\/yg-1-dtx418020-solid-carbide-jobber-drill-bit-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
