Built from solid carbide and coated with a multilayer TiAlN finish, this bit delivers hardness and heat resistance needed for demanding materials. It cuts in a right-hand direction with a 140-degree split-point geometry and two regular spiral flutes, providing self-centering action and efficient chip evacuation. The straight cylindrical shank measures 0.2362 inches in diameter, and the overall length is 2.5984 inches. This is a Series B976A tool conforming to DIN 6537K specification.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for CNC machining centers, screw machines, and manual drilling operations where short, rigid tooling is required to minimize deflection and maximize positional accuracy. The stub-length body reduces overhang, making it appropriate for high-feed-rate applications in steel, cast iron, stainless, and other ferrous and non-ferrous alloys. Coolant-through capability allows internal delivery of cutting fluid directly to the cutting edge, extending tool life in production environments. It is typically used by machinists and toolroom technicians in production shops, job shops, and maintenance machining operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating provides thermal barrier and oxidation resistance at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle for self-centering entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eCoolant-through design delivers cutting fluid internally to the drill tip\u003c\/li\u003e\n\u003cli\u003eStub length body minimizes deflection for tight-tolerance hole location\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537K specification for consistent dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Series B976A screw machine length drill bit for use in toolholders and chucks accepting a straight cylindrical shank with a 0.2362-inch shank diameter, compatible with standard CNC and manual drilling setups requiring a Letter A or 0.2340-inch nominal bore diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified machinists following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the straight shank in a precision drill chuck or collet holder to the appropriate holding depth using proper tooling torque practices per machine manufacturer guidelines. Verify coolant-through connections are properly engaged before running at operating speed if internal coolant is used.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2340 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional Inch)\u003c\/strong\u003e: 15\/64\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\u003eDrill Point 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\u003eFlute Length\u003c\/strong\u003e: 1.1024 inches (28.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5984 inches (66.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inches (6.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (36.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.7874 inches (20.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0392 inches (1.00 mm)\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: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.0002 to +0.0006 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B976A\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: 0.05 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: 4054505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728753066290,"sku":"4054505","price":140.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a760e98094fc17d0c2c705cf06487ece.jpg?v=1788695842","url":"https:\/\/voomisupply.com\/products\/kennametal-4054505-drill-bit-letter-a-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
