It measures 6.00 mm (0.2362 inches) in diameter with an overall length of 82.00 mm (3.2283 inches) and a flute length of 44.00 mm (1.7323 inches). The 140-degree split point reduces walking and lowers thrust force at entry. The multi-layer AlTiN proprietary coating delivers high heat resistance and extended tool life in hard and abrasive workpiece materials. This drill is used by machinists and tool-and-die professionals running CNC machining centers, drill presses, and manual mills.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production drilling in ferrous metals, cast iron, stainless steel, and high-temperature alloys where heat buildup is a primary concern. The AlTiN coating performs well in dry or minimum-quantity lubrication (MQL) cutting conditions. The straight cylindrical shank provides consistent runout in standard drill chucks and collet holders. With a 5xD flute-to-diameter ratio, this jobber drill handles moderate-depth holes typical of general machining work without requiring a specialty deep-hole drill.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction — grade KCP15B — for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eMulti-layer AlTiN coating provides thermal barrier and reduces built-up edge in ferrous cutting\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces thrust and self-centers on entry without a pilot hole in most applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and ER collets\u003c\/li\u003e\n\u003cli\u003eMaximum drilling depth of 35.00 mm supports typical through-hole and blind-hole production work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-grade solid carbide jobber drill for use in CNC machining centers, drill presses, and milling machines equipped with standard drill chucks or collet systems accepting a 6.00 mm straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this drill bit should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before loading or removing the drill. Seat the straight shank fully and evenly in the collet or chuck to minimize runout before tightening. Follow the machine manufacturer and cutting tool manufacturer feed and speed recommendations for the specific workpiece material — do not exceed the maximum drilling depth of 35.00 mm for this tool without consulting application guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 82.00 mm (3.2283 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 44.00 mm (1.7323 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\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 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: 1.31 mm\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: KCP15B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Multi-layer AlTiN (Aluminum Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 6781490\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738045710642,"sku":"6781490","price":213.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26cfcb21e9f345be8a465f38ba769470_6d8bf141-0e97-4d9f-aaff-6fb2fb34bf77.jpg?v=1788795807","url":"https:\/\/voomisupply.com\/products\/kennametal-6781490-carbide-jobber-drill-6mm-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
