It measures 8.43 mm (0.2610 inches) in diameter with a 140-degree split-point tip that reduces walking and improves entry accuracy on flat and curved surfaces. The titanium nitride (TiN) coating extends tool life by increasing surface hardness and reducing friction. At 3.5827 inches overall length with a 2.0866-inch flute, this bit fits standard drill chucks and CNC machining centers. It is suited for production environments where consistent hole quality and tool longevity are priorities.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in metalworking and machining applications where tight tolerances and clean hole finishes are required. The right-hand cut, regular spiral flute design handles general-purpose drilling in ferrous and non-ferrous metals, engineering plastics, and composite materials. It is commonly deployed in job shop, maintenance, and light manufacturing settings. The straight shank is compatible with standard drill chucks and collet-style tool holders used in both manual drill presses and CNC equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and extends tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle improves self-centering and reduces thrust force\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight shank fits standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003e6xD flute-to-diameter ratio supports drilling up to 43.00 mm depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber length drill bit for use in standard drill chucks and collet-style tool holders on drill presses, lathes, and CNC machining centers accepting an 8 mm straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and tool-and-die professionals. Secure the straight shank firmly in a collet or chuck before operation and verify runout with a dial indicator when close tolerances are required. Power down and de-energize all spindle drives before changing tooling. Do not exceed the rated maximum drilling depth of 43.00 mm to avoid deflection or 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: 8.43 mm (0.2610 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\u003eOverall Length\u003c\/strong\u003e: 91.00 mm (3.5827 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53.00 mm (2.0866 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 43.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.11 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 6xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 4150717\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51746022949170,"sku":"4150717","price":159.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0badca568ffbb1898d59202e58ae8ad_2a003994-2e40-4851-8736-5d36b20d8b74.jpg?v=1788866385","url":"https:\/\/voomisupply.com\/products\/kennametal-4150717-jobber-drill-bit-8-43mm-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
