Built to Series 550 standards and conforming to DIN 338 and NAS 907 Type J specifications, this bit features a 135-degree split point for fast penetration and reduced walking on contact. The straw-finish cobalt construction provides elevated heat resistance compared to standard HSS, making it well suited for production drilling in steel and stainless steel. At 3.30 mm in diameter with a 2.5591-inch overall length, it fits standard drill chucks and CNC spindles without modification. Two regular spiral flutes evacuate chips efficiently during the cut.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for drilling steel and stainless steel in industrial, maintenance, and fabrication environments. The split point geometry eliminates the need for a center punch on most setups, reducing cycle time on repetitive operations. The web-thinned, tapered web configuration reduces thrust requirements, which is especially useful when working with tougher alloys. It is appropriate for use in hand-held drill motors, drill presses, and CNC machining centers. The straight cylindrical shank accepts standard drill chucks across a wide range of equipment. Typical users include machinists, maintenance technicians, and fabricators working in metal trade and industrial service settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction with straw finish for enhanced heat and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates walking at contact\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting resistance in hard alloys\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 and NAS 907 Type J specifications for consistent dimensional control\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0007 inches for precision fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber drill for applications requiring a 3.30 mm straight-shank cobalt bit; compatible with standard drill chucks and CNC tool holders accepting a 0.1299-inch shank diameter across drill presses, hand drills, and machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or trade technicians familiar with rotating cutting tools. Secure the straight shank firmly in the chuck before operation and verify runout is within acceptable limits before drilling. Ensure the workpiece is clamped securely to prevent movement during the cut. Do not exceed the recommended feed and speed ranges for the workpiece material and drill diameter; excessive heat will degrade cobalt performance and reduce tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.30 mm (0.1299 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 65.00 mm (2.5591 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36.00 mm (1.4173 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.30 mm (0.1299 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 29 mm (1.1417 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\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\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 338, NAS 907 Type J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 550\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 46460\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51730509594930,"sku":"46460","price":71.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e32df04ad069ba80c0fd8951c3a7bca5.jpg?v=1788718713","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-46460-cobalt-jobber-drill-bit-3-30-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
