It features a multilayer TiAlN coating for extended tool life in demanding applications. The overall length is 66.00 mm (2.598 inches), with a 28.00 mm (1.102 inch) flute length and a maximum drilling depth of 23.00 mm (0.906 inch). A tapered web configuration and regular spiral flute geometry support efficient chip evacuation. This drill is intended for use by machinists and tool-room technicians working in production and precision drilling environments.\u003c\/p\u003e\u003cp\u003eThe 4149128 is suited for drilling steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. It is built to DIN 6537K specification, placing it in a 5xD flute-to-diameter ratio category appropriate for moderate-depth through-hole and blind-hole applications. Coolant-through capability makes it a practical choice for high-cycle CNC machining operations where heat management is critical. It is typically found in job shops, production lines, and tool-and-die environments where tight diameter tolerance and consistent hole quality are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\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 centering on entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed, high-cycle drilling operations\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification ensures dimensional consistency\u003c\/li\u003e\n\u003cli\u003eTapered web and regular spiral flute promote reliable chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement-style solid carbide jobber drill conforming to DIN 6537K, compatible with standard straight-shank tool holders and collet chucks accepting a 6 mm (0.625 inch) shank diameter across CNC machining centers and drill presses.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out. Secure the straight cylindrical shank firmly in a collet or drill chuck rated for the shank diameter before operation. Verify coolant-through connections and flow rate are properly set before initiating a cutting cycle. Do not use this drill in hand-held drill applications; it is intended for machine tool use only.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.10 mm (0.1220 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 (2.598 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28.00 mm (1.102 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 23.00 mm (0.906 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.417 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.50 mm (0.020 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\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\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 4149128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740076114226,"sku":"4149128","price":156.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6047723244c39e297ff48cf30f8b8e5b_7c91a505-d37d-4620-9c8b-199fddd9779b.jpg?v=1788822137","url":"https:\/\/voomisupply.com\/products\/kennametal-4149128-solid-carbide-jobber-drill-3-10-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
