The 12.30 mm (0.4843 inch) diameter bit features a 140-degree point angle for reduced thrust and self-centering entry, and a multilayer TiAlN coating that extends tool life at elevated cutting temperatures. With a regular spiral flute geometry and an overall length of 124.00 mm (4.882 inches), this drill is built to handle steel, stainless steel, cast iron, and aluminum in both manual and CNC applications. Coolant-through capability supports chip evacuation in deep-hole drilling.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is suited for use in CNC machining centers, drill presses, and automated production equipment where consistent bore geometry and tight tolerances are required. The straight cylindrical shank and DIN 6537K specification make it a standard fit for ER-style collet chucks and similar toolholding systems. Primary workpiece materials include steel, stainless steel, cast iron, and aluminum and non-ferrous alloys. The 5xD flute-to-diameter ratio and 60.00 mm maximum drilling depth support typical through-hole and blind-hole operations in medium-to-heavy-duty machining. Machinists, tool and die makers, and production line operators are the typical end users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating for thermal resistance and extended tool life at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and heat control in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eDIN 6537K specification for dimensional consistency and interchangeable toolholding\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration reduces cutting resistance and aids re-sharpening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in straight-shank collet chucks, ER toolholders, and drill chucks conforming to DIN standards.

Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the shank. Verify runout with a dial indicator after clamping, as excessive runout accelerates wear on carbide tooling. Activate coolant-through flow before beginning the cut to maintain chip evacuation and thermal control.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 12.30 mm (0.4843 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 124.00 mm (4.882 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 77.00 mm (3.032 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 60.00 mm (2.362 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 14 mm (0.1406 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45 mm (1.772 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 2.11 mm (0.083 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\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\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\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: -0.0007 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\u003eDrill Bit Size Range\u003c\/strong\u003e: 10.00 mm to 12.50 mm (0.4000 to 0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.38 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 4149318\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739694170418,"sku":"4149318","price":372.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6047723244c39e297ff48cf30f8b8e5b_bf12cd02-6d95-48a4-a51f-514b1970d817.jpg?v=1788817906","url":"https:\/\/voomisupply.com\/products\/kennametal-4149318-solid-carbide-jobber-drill-12-30-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
