Built to DIN 6537K standards and finished with a TiAlN coating, this bit delivers extended tool life in abrasive and hard materials. It features a 140-degree split point, web-thinned geometry for reduced thrust and improved chip evacuation, and a straight cylindrical shank measuring 8.00 mm in diameter. At 79.00 mm overall length with a 34.00 mm flute length, it fits standard screw machine and CNC drilling setups. Material grade KC7315 with the Dynapoint High Performance designation makes this a production-grade tool for shops running high-cycle operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling cast iron and steel in residential, commercial, and industrial machining applications. The short overall length and rigid solid carbide construction make it well-matched for CNC machining centers, turret lathes, and screw machines where runout control and repeatable hole tolerances are critical. The 140-degree point geometry is particularly effective when entering hardened or work-hardened steel surfaces. Two regular spiral flutes provide consistent chip clearance through the 24.00 mm maximum drilling depth.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction, material grade KC7315 Dynapoint High Performance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree split point with web-thinned, parallel web configuration for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification for consistent dimensional standards\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank, 8.00 mm diameter, for positive chuck grip\u003c\/li\u003e\n\u003cli\u003eMaximum drilling depth of 24.00 mm with 34.00 mm flute length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in cast iron and steel workpieces.

Verify chuck or collet bore matches the 8.00 mm shank diameter before mounting. Confirm recommended cutting speeds and feed rates for the workpiece material per the machine tool manufacturer and tooling guidelines before starting a cut. Do not use this bit in hand-held drilling applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.20 mm (0.2441 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 79.00 mm (3.1102 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (0.3150 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm (1.4173 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 24.00 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: 1.00 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\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eMaterial Grade\u003c\/strong\u003e: KC7315\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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: No\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.006 to +0.021 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: B966A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0904 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: 1982397\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727071641906,"sku":"1982397","price":148.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b47c9b8099882b05bb80a1c6e0c51a3.jpg?v=1788672819","url":"https:\/\/voomisupply.com\/products\/kennametal-1982397-screw-machine-drill-bit-6-20-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
