Measuring 3\/16 inch (0.1875 inch) in diameter with a 140-degree point angle, this bit cuts right-hand with a regular spiral flute pattern and an AlTiN (aluminum titanium nitride) coating for extended tool life at elevated temperatures. The overall length is 68.00 mm (2.68 inches), making it well-suited for short-reach, rigid setups typical in screw machine and CNC drilling operations. Coolant-through capability supports chip evacuation and thermal management in deep-hole applications. It is part of the K210 Series, material grade KCMS15, and ships as a single unit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in precision machining environments including screw machine shops, CNC machining centers, and automated production cells. Its 3xD flute-to-diameter ratio and straight cylindrical shank make it compatible with standard drill chucks and collet holders. The AlTiN coating supports drilling in hardened steels, stainless, cast iron, and high-temperature alloys where heat resistance is critical. Maximum drilling depth is 0.89 inch (22.60 mm), and it is appropriate for applications requiring tight tolerances and consistent hole quality in high-volume runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction, material grade KCMS15, for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating extends tool life in high-heat and abrasive cutting conditions\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust and improves centering on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and heat control in deep holes\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, 2-flute geometry for efficient chip flow in production drilling\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard collet and drill chuck toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a screw machine length replacement drill bit within the KENNAMETAL K210 Series, compatible with standard straight-shank drill chucks and collet holders accepting 3\/16 inch (0.1875 inch) shank diameters in CNC and manual drilling setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck or collet runout is within acceptable limits before seating the shank, as excess runout accelerates carbide wear. When using the coolant-through feature, confirm coolant supply lines and pressure are set per machine specifications before starting the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 68.00 mm (2.68 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 29.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.50 mm (1.437 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.89 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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: 3xD\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\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: KCMS15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: K210\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.76 x 0.39 x 0.39 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.029 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: 6351161\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732000735538,"sku":"6351161","price":238.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/06aad078034786c7cd211429e76a326b.jpg?v=1788737884","url":"https:\/\/voomisupply.com\/products\/kennametal-6351161-screw-machine-drill-bit-3-16-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
