It features a multilayer TiAlN coating applied over a high-performance carbide substrate, which extends tool life in demanding materials by reducing heat buildup and edge wear. The drill runs in a right-hand cutting direction with a regular spiral flute configuration and a straight cylindrical shank. Overall length is 91.00 mm (3.5827 inches), with a 53.00 mm (2.0866 inch) flute length. Coolant-through capability is included, making it suitable for high-speed drilling operations where chip evacuation and thermal management are critical. This drill is intended for installation by machinists and toolroom professionals operating CNC machining centers and drill presses.\u003c\/p\u003e\n\u003cp\u003eThis drill is rated for use in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. Its 5xD flute-to-diameter ratio supports deeper hole applications relative to standard jobber geometry. The straight shank diameter of 8.00 mm (0.3150 inch per the shank spec) accommodates standard collets and drill chucks commonly used on vertical machining centers, CNC lathes, and bench-top drill presses. The 140-degree point angle is well suited to harder workpiece materials where a more aggressive point geometry reduces thrust force and improves hole entry accuracy. Typical applications include production drilling in metalworking shops, maintenance repair environments, and precision fabrication settings.\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 reduces friction and extends tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle optimized for steel and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and thermal control at depth\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with tapered web configuration for consistent chip flow\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 6537K specification for dimensional and geometric accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for machining centers, CNC lathes, and drill presses accepting straight-shank tooling. Primary workpiece materials include steel, stainless steel, cast iron, aluminum, and non-ferrous alloys. Drill bit size falls within the 6.00 mm to 7.00 mm (0.2500 to 0.3000 inch) diameter range per the DIN specification designation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or toolroom technicians familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and the tool holder is de-energized before loading or removing the drill. Verify collet or chuck bore matches the 8.00 mm shank diameter before securing; improper seating can cause runout and premature tool failure. When running with coolant-through capability, confirm the machine tool spindle and toolholder assembly support internal coolant delivery before engaging the coolant circuit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.70 mm (0.2638 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\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\u003eOverall Length\u003c\/strong\u003e: 91.00 mm (3.5827 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53.00 mm (2.0866 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 43.00 mm (1.6929 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm (1.4173 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.13 mm (0.0444 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: -0.0006 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 Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum, Non-Ferrous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: 4149236\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743968985394,"sku":"4149236","price":171.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c645df15533021c88c743917c52012ce_ba4d734a-b9be-4622-b6a0-8b37e6712461.jpg?v=1788852145","url":"https:\/\/voomisupply.com\/products\/kennametal-4149236-solid-carbide-jobber-drill-6-70mm","provider":"Voomi Supply","version":"1.0","type":"link"}
