Built from solid carbide and coated with a multilayer TiAlN finish, this bit handles hard workpiece materials and elevated cutting temperatures without breaking down. The 140-degree split point reduces walking at entry and requires less thrust than standard point geometries. At 1.9685 inches overall length with a 0.6299-inch flute length, this bit is optimized for short, rigid setups where tool deflection must be minimized. It is installed by machinists and tooling technicians on CNC machining centers, drill presses, and screw machines.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for stub-length drilling applications in metalworking, production machining, and precision component manufacturing. The 7\/64-inch diameter and straight cylindrical shank make it compatible with standard drill chucks and collet systems. The coolant-through design channels cutting fluid directly to the tip, extending tool life and improving chip evacuation in deep or interrupted cuts. It follows DIN 6537K specification, making it interchangeable in tooling setups designed to that standard. Typical applications include drilling ferrous and non-ferrous metals in automotive, aerospace, and general precision machining operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in metal cutting\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle reduces entry walking and lowers thrust requirements\u003c\/li\u003e\n\u003cli\u003eCoolant-through design directs fluid to the cutting edge for improved chip evacuation\u003c\/li\u003e\n\u003cli\u003eTapered web configuration maintains strength while reducing cutting forces\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification for consistent dimensional interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production tooling option for machining setups requiring a 7\/64-inch stub-length carbide drill bit with a straight cylindrical shank conforming to DIN 6537K specification. Compatible with standard drill chucks and collet systems accepting a 0.1181-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and CNC tooling technicians. Ensure the spindle is fully stopped and the machine is powered down or placed in a safe lockout state before changing tooling. Confirm shank seating in the chuck or collet before operation and verify coolant-through passages are clear and connected to the machine coolant supply. Do not exceed the rated maximum drilling depth of 0.4331 inches per pass without retracting to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/64 inches (0.1094 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.9685 inches (50.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.6299 inches (16.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1181 inches (3.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1024 inches (28.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.4331 inches (11.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0176 inches (0.45 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN Multilayer\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.002 to +0.012 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B976Z\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\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: 0.012 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: 4042547\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732459323698,"sku":"4042547","price":140.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8170d640d4c70214413e899c0892cbe0.jpg?v=1788743001","url":"https:\/\/voomisupply.com\/products\/kennametal-4042547-drill-bit-7-64-in-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
