Manufactured from solid carbide and coated with TiAlN, it delivers extended tool life at elevated cutting speeds compared to high-speed steel alternatives. The bit features a 132-degree drill point angle optimized for reduced thrust and accurate entry on hard workpieces. A web-thinned, tapered web configuration improves chip evacuation and lowers cutting forces. At 6.5 mm in diameter with a 105 mm overall length, this drill is suited for production machining environments where consistency and tool longevity are priorities. A coolant-through design supports internal coolant delivery to the cutting zone.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for cutting cast iron and steel. It fits into machining centers, CNC drilling machines, and manual drill presses equipped with a straight shank collet or chuck. The straight-cylindrical shank measures 8 mm in diameter, making it compatible with standard ER collet systems and equivalent toolholding. The spiral flute geometry promotes consistent chip clearing during through-hole and blind-hole drilling operations in both production and job shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in ferrous material applications\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life at high cutting temperatures\u003c\/li\u003e\n\u003cli\u003e132-degree point angle reduces entry thrust and improves hole location accuracy\u003c\/li\u003e\n\u003cli\u003eCoolant-through channels deliver coolant directly to the cutting edge\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces cutting forces and aids chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute for standard clockwise cutting operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in cast iron and steel.

Ensure the collet or chuck is clean and undamaged before seating the shank. Verify coolant-through compatibility with the machine spindle before use if internal coolant delivery is required. Do not exceed the recommended maximum drilling depth of 57 mm for this tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B978\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.5 mm (0.2559 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 105 mm (4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 67 mm (2.6378 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm (0.3150 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.4173 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 57 mm (2.2440 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 132 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.36 mm (0.0535 inches)\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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: +0.006 to +0.021 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0882 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: 1913621\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748577706290,"sku":"1913621","price":417.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3ddbe50093fd63eee33c1f7074bf1d3.jpg?v=1788895358","url":"https:\/\/voomisupply.com\/products\/kennametal-1913621-taper-length-drill-bit-6-5-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
