It features a 140-degree point angle for aggressive entry and reduced thrust, and a multilayer TiAlN coating that extends tool life in abrasive and elevated-temperature cutting conditions. The drill measures 3.70 mm in diameter with an overall length of 66.00 mm (2.5984 inches) and a flute length of 28.00 mm (1.1024 inches). With a 5xD flute-to-diameter ratio and tapered web configuration, it delivers stable chip evacuation and consistent hole quality. Installed by machinists and tool-and-die professionals in CNC and manual drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis drill is suited for through-hole and blind-hole applications in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. The 6 mm straight-cylindrical shank (0.5156 inches) seats in standard collet chucks and drill holders common to CNC machining centers, drill presses, and manual lathes. A maximum drilling depth of 23.00 mm (0.9055 inches) makes it appropriate for short-run production and maintenance drilling tasks where carbide rigidity and coating performance are required over high-speed steel alternatives. Coolant-through capability supports wet drilling in harder materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and heat resistance in hard-material drilling\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating extends tool life in steel and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery for deep or high-feed drilling\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, 2-flute geometry promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537K specification for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard collet chucks and drill holders accepting a 6 mm straight-cylindrical shank.

Confirm shank seating and collet torque per the machine tool manufacturer's guidelines before initiating a cut. Do not exceed the rated maximum drilling depth of 23.00 mm per pass without retracting to clear chips, particularly in blind-hole operations. Internal coolant pressure should be set per the machine tool specifications when using the coolant-through feature.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.70 mm (0.1457 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\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (2.5984 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28.00 mm (1.1024 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.5156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.4173 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 23.00 mm (0.9055 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.61 mm (0.0240 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\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  \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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4149188\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743916196146,"sku":"4149188","price":157.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6047723244c39e297ff48cf30f8b8e5b_1a1456dc-7113-4250-b847-0966b678dea4.jpg?v=1788851238","url":"https:\/\/voomisupply.com\/products\/kennametal-4149188-solid-carbide-jobber-drill-3-70-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
