The bit carries a multilayer TiAlN coating, a 140-degree split point, and a right-hand regular spiral flute geometry. It measures 4.8819 inches overall length with a flute length of 3.0315 inches. Rated to a drill bit diameter tolerance of -0.0007 to 0.0000 inches, it holds tight dimensional control for precision hole work. This drill is intended for use by machinists and tool-and-die professionals working on CNC and manual drilling operations where tool life and hole quality are critical.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is suited for production drilling in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. The 31\/64 inch cutting diameter and straight cylindrical shank allow straightforward chuck mounting in standard drill presses, machining centers, and CNC turning equipment. The coolant-through design supports internal coolant delivery, making it well suited for deeper hole applications where heat buildup and chip evacuation are concerns. It conforms to DIN 6537K specification, which governs solid carbide drill geometry and dimensional tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating improves heat resistance and wear performance in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust force and improves self-centering at entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery for chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet holders without adapters\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537K specification for consistent interchangeability with other DIN-standard tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling steel, stainless steel, cast iron, aluminum, and non-ferrous materials.

Verify chuck or collet runout before use, as excessive runout accelerates carbide breakage. Confirm that the machine spindle and coolant system are rated for the feed and speed parameters required by the workpiece material and drill diameter. Carbide tooling is brittle  -  avoid side loading or using the drill as a reamer.\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 inches (0.4844 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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: Multilayer TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.8819 inches (124.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.0315 inches (77.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3906 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.7717 inches (45.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.3622 inches (60.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0832 inches (2.11 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4149319\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740127297842,"sku":"4149319","price":411.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c21e50cf148da231f612039c08e77472.jpg?v=1788822626","url":"https:\/\/voomisupply.com\/products\/kennametal-4149319-solid-carbide-jobber-drill-31-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
