It carries a multilayer TiAlN coating over a solid carbide substrate, delivering exceptional heat resistance and wear life at elevated cutting speeds. The 140-degree split point geometry with web thinning allows aggressive entry and reduces thrust force, making it well suited for production drilling and tight-tolerance work. With an overall length of 4.0157 inches and a 27\/64-inch (0.4219 inch) cutting diameter, this bit is sized for stub-length rigidity in applications where deflection control matters.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for right-hand cutting in cast iron and steel workpieces, which are among the most common materials encountered in machining, fabrication, and mechanical service environments. The straight cylindrical shank at 0.4724 inches (12.00 mm) in diameter fits standard drill chucks and collet holders. Coolant-through capability supports high-speed production runs where chip evacuation and thermal management are priorities. It conforms to DIN 6537K specification, making it a recognized standard for screw machine length carbide drills used across manufacturing and maintenance trades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with multilayer TiAlN coating for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree standard point with web thinning reduces entry thrust and improves hole quality\u003c\/li\u003e\n\u003cli\u003eCoolant-through design aids chip evacuation and heat control during production drilling\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 0.4724 inches (12.00 mm) fits standard toolholders\u003c\/li\u003e\n\u003cli\u003eRegular spiral, 2-flute configuration with parallel web for consistent chip flow\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537K specification for screw machine length carbide drills\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 6537K-compliant screw machine length drill bit for use in cast iron and steel workpieces.

Power down and lock out the machine spindle before installing or removing the bit. Confirm the toolholder is clean and the shank seats fully before securing the chuck or collet to the manufacturer torque specification. Carbide is brittle — avoid lateral loading, interrupted cuts beyond the tool rating, and dropping the bit on hard surfaces, as impact can cause chipping or fracture.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 27\/64 inches (0.4219 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0157 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.1654 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4724 inches (12.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.7717 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.5750 inches\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: 0.0720 inches\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\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\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: +0.007 to +0.025 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B976\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0529 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: 2649377\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51736926585138,"sku":"2649377","price":327.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17b90251a00ac19d61dfa31017028020.jpg?v=1788782007","url":"https:\/\/voomisupply.com\/products\/kennametal-2649377-screw-machine-drill-bit-27-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
