Built to DIN 6537K specification, it features a multilayer TiAlN coating that extends tool life in abrasive and high-temperature cutting conditions. The 135-degree split-point geometry reduces entry force and minimizes walking on flat or curved surfaces. At 7 mm in diameter with a straight-cylindrical shank measuring 8 mm, this bit fits standard collet chucks and drill holders across CNC machining centers and manual drill presses. Coolant-through capability supports chip evacuation and heat management during deep-hole operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production machining environments where tight tolerances and consistent hole quality are required. The 5xD flute-to-diameter ratio and 91 mm overall length make it appropriate for structural steel, stainless, cast iron, and hardened alloy applications. It is typically installed by machinists and tool-and-die professionals working in job shops, aerospace, automotive, and general manufacturing. The KCPK15 material grade is optimized for hard and abrasive workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction in material grade KCPK15 for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating improves heat resistance and tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003e135-degree standard point angle reduces thrust force and prevents bit walk\u003c\/li\u003e\n\u003cli\u003eCoolant-through design for effective chip removal and thermal control in deep holes\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for compatibility with standard collet and drill chuck systems\u003c\/li\u003e\n\u003cli\u003eTapered web configuration maintains core strength along the full flute length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers and manual drill presses accepting straight-cylindrical shank drill bits with an 8 mm shank diameter, conforming to DIN 6537K specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Secure the shank fully within the collet or drill chuck to the manufacturer-specified engagement depth before operation. Ensure the machine spindle is fully stopped and locked out before changing or inspecting tooling. Verify coolant-through passages are clear and supply pressure is set according to the machine tool specifications before drilling operations begin.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7 mm (0.2756 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 91 mm (3.5827 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53 mm (2.0866 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm (0.3150 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: 43 mm (1.6929 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.31 mm (0.0516 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 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: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: KCPK15\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\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0002 to 0.0008 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.115 pounds\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: 4112630\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750772080946,"sku":"4112630","price":374.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/705b77b4cb43652f3437c838ef1b4c53_0fed6084-101a-42a8-9e98-5e0d04f0836a.jpg?v=1788919560","url":"https:\/\/voomisupply.com\/products\/kennametal-4112630-carbide-jobber-drill-bit-7mm-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
