Featuring a 140-degree split point with web thinning and a TiAlN (titanium aluminum nitride) coating, this drill reduces thrust force on entry and extends tool life in abrasive and heat-intensive cutting conditions. The right-hand, regular spiral flute geometry promotes efficient chip evacuation. Overall length is 4.0551 inches with a 2.4016-inch flute length and a 0.3937-inch straight cylindrical shank. Coolant-through capability supports high-speed, deep-hole drilling operations. Manufactured to DIN 6537L specification.\u003c\/p\u003e\u003cp\u003eThis drill is suited for production machining environments where precision and tool longevity are critical. Primary workpiece materials include steel, stainless steel, cast iron, aluminum, and other non-ferrous metals. The coolant-through design makes it appropriate for CNC machining centers and drill presses where internal coolant delivery is available. Maximum drilling depth reaches 1.9290 inches, making it a practical choice for through-hole and moderate-depth blind-hole applications across metal fabrication, aerospace, automotive, and general manufacturing 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\u003eTiAlN coating reduces heat buildup and extends cutting life in steel and stainless steel\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with web thinning for reduced entry thrust and improved centering\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed drilling and chip flushing in deep holes\u003c\/li\u003e\n\u003cli\u003eRight-hand regular spiral flute promotes consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank (0.3937 inches) for compatibility with standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eManufactured to DIN 6537L specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and other machine tool setups capable of accepting a 0.3937-inch straight shank.

Ensure the shank is fully seated and properly torqued in the chuck or collet before operation. When using the coolant-through feature, verify coolant pressure and flow rate are within the machine's specified range before beginning a drilling cycle. Inspect the drill point for wear or chipping before each use, as carbide tooling is brittle and should not be used if the cutting edge is damaged.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: Q\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3320 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0551 inches (103 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.4016 inches (61 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches (10 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 Length\u003c\/strong\u003e: 1.5748 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.9290 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0560 inches (1.42 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.006 to +0.021 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537L\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\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1638 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: 2658220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728481616178,"sku":"2658220","price":250.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1753e8547b8645a33f4081693900f57f.jpg?v=1788691903","url":"https:\/\/voomisupply.com\/products\/kennametal-2658220-solid-carbide-jobber-drill-letter-q","provider":"Voomi Supply","version":"1.0","type":"link"}
