Built to DIN 6537K specification and manufactured in the B966A series, it carries a TiAlN coating and a 140-degree split point with web thinning for fast, accurate starts without a center punch. At 8.90 mm (0.3504 inches) diameter with a straight cylindrical 10.00 mm shank, this bit handles the short, rigid setup typical of CNC machining centers and screw machines. The Dynapoint High Performance material grade KC7315 gives it the wear resistance needed for extended production runs. Licensed machinists, tool-and-die shops, and production floor technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use in screw machine and short-run CNC applications where a compact overall length and rigid shank are required. Primary workpiece materials are cast iron and steel. The 47.00 mm flute length and 35.00 mm maximum drilling depth suit it for through-holes and moderate blind-hole work in ferrous stock. Its straight cylindrical shank seats directly in standard drill chucks and collet holders without an adapter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN coating for heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with web thinning reduces thrust force and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction in grade KC7315 (Dynapoint High Performance) for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry for reliable chip clearing in cast iron and steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for screw machine and CNC drilling applications in cast iron and steel workpieces, consistent with B966A series specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed by qualified machinists with the machine in a full stop and locked-out state per applicable lockout\/tagout procedures. Seat the straight shank fully into the chuck or collet holder and verify runout before cycling. Do not exceed the rated maximum drilling depth of 35.00 mm per pass without retracting to clear chips. Consult machine tool and cutting fluid manufacturer guidelines for appropriate speeds, feeds, and coolant strategy when drilling cast iron or steel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.90 mm (0.3504 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 89.00 mm (3.5039 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40.00 mm (1.5748 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 35.00 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: 1.50 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\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 with Web Thinning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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 (Dynapoint High Performance)\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1598 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: 2425145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733222490418,"sku":"2425145","price":167.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca6d56b8986e9f1cb2da0e408cfeea2e.jpg?v=1788752953","url":"https:\/\/voomisupply.com\/products\/kennametal-2425145-drill-bit-8-90mm-tialn-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
