It features an 8.80 mm diameter, a 140-degree split point, and a multilayer TiAlN coating that improves heat resistance and extends tool life at elevated cutting speeds. The straight cylindrical shank measures 10 mm in diameter, and the overall length is 103 mm (approximately 4.06 inches). Two right-hand spiral flutes with a regular spiral configuration evacuate chips efficiently during through-hole and blind-hole drilling. Licensed tradespeople and machining professionals working with ferrous and non-ferrous stock will find this bit suited for production-volume drilling.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is engineered for use in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. The 5xD flute-to-diameter ratio and 49 mm maximum drilling depth make it well-matched to CNC machining centers, drill presses, and manual equipment where consistent hole tolerance is required. The tapered web configuration aids chip clearing and reduces thrust during entry. It conforms to DIN 6537K specification, which governs jobber-length solid carbide drills used across general machining and precision metalworking environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8.80 mm diameter with a tolerance of -0.0006 to 0.0000 inches for tight, repeatable hole sizing\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating increases surface hardness and thermal resistance for extended tool life\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance superior to high-speed steel in hard materials\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, two-flute design promotes efficient chip evacuation in deep and interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank (10 mm diameter) fits standard drill chucks and collet systems without adapters\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537K specification for dimensional consistency across tool changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 6537K-compliant solid carbide jobber drill for use in standard drill chucks and collet holders accepting a 10 mm straight shank, compatible with CNC machining centers and conventional drill press setups targeting steel, stainless steel, cast iron, aluminum, and non-ferrous workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool setup and machine operation. Ensure the machine spindle is fully stopped and the drill is seated and secured in the chuck or collet before starting the spindle. Do not use this drill for non-metallic materials outside its rated workpiece range, as this can cause premature edge failure. Verify spindle speed and feed rates against the material being machined before beginning a cut, as improper parameters accelerate wear and can cause tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.80 mm (0.3465 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\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003c\/strong\u003e: Multilayer TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 103 mm (4.0551 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 61 mm (2.4016 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 49 mm (1.9291 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40 mm (1.5748 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.50 mm (0.0589 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0006 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum, Non-Ferrous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 4150722\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743476515122,"sku":"4150722","price":161.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/027550a92e9fb7c9c67a753ee7e2e1a8_625d7c86-f5a6-4732-bd4c-16f295a4a6da.jpg?v=1788847463","url":"https:\/\/voomisupply.com\/products\/kennametal-4150722-solid-carbide-jobber-drill-8-80mm","provider":"Voomi Supply","version":"1.0","type":"link"}
