It features a 27\/64-inch (0.4219 inch) diameter, a 140-degree point angle, and a multilayer TiAlN coating for extended tool life under heat and abrasion. The overall length is 4.646 inches (118.00 mm), and the drill follows DIN 6537K geometry with a straight cylindrical shank. Coolant-through capability supports chip evacuation and thermal management in deep-hole applications. This is a right-hand, two-flute design with a regular spiral and tapered web configuration. Typically installed by machinists and CNC operators in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis drill is suited for use in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. The 5xD flute-to-diameter ratio and 2.795-inch flute length support drilling depths up to 2.205 inches (56.00 mm). The straight shank diameter is 12 mm (0.4724 inch nominal per DIN, with a shank length of 1.772 inches). Applications include through-hole and blind-hole drilling on CNC machining centers and manual drill presses where tight tolerances and consistent performance are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating reduces thermal load and extends tool life at higher cutting speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust force and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design directs fluid to the cutting zone for chip flushing and heat control\u003c\/li\u003e\n  \u003cli\u003eDIN 6537K specification ensures dimensional conformance and interchangeability\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of -0.0007 to 0.0000 inch holds tight finished-hole size requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, stainless steel, cast iron, aluminum, and non-ferrous workpiece materials per the listed primary workpiece material specifications.

Ensure the straight shank is fully seated and clamped in a clean, undamaged collet or drill chuck before operation. Verify coolant-through passages are unobstructed and supply pressure is set to the machine and tooling manufacturer guidelines before initiating a cut. Do not use this drill in hand-held portable drilling applications; it is intended for rigid machine-tool spindle use only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 27\/64 inch (0.4219 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.646 inches (118.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.795 inches (71.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.205 inches (56.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 mm straight cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.772 inches (45 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.072 inch (1.83 mm)\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\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\u003eCoating\u003c\/strong\u003e: Multilayer TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inch\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  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum, Non-Ferrous\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: 4149299\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742560747826,"sku":"4149299","price":310.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2946d6af4a4e2d7c5c07bafe869c836.jpg?v=1788838100","url":"https:\/\/voomisupply.com\/products\/kennametal-4149299-carbide-jobber-drill-27-64-in-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
