Built to Series 550 specifications, it features a 10 mm diameter, a 135-degree split point, and a gold finish coating. The split point geometry reduces walking on entry and allows drilling to begin without a center punch in many setups. The cobalt steel construction provides heat resistance, making this bit suited for hard and abrasive materials that would accelerate wear in standard high-speed steel tooling. Overall length is 5.236 inches with a flute length of 3.425 inches. It is installed and used by machinists, tool-and-die professionals, and maintenance technicians working in industrial and fabrication environments.\u003c\/p\u003e\n\u003cp\u003eThe 46488 is rated for primary use on titanium and other hard metals, consistent with NAS 907 Type J and DIN 338 standards. The straight-cylindrical shank fits standard drill chucks and CNC tool holders with a shank diameter matching the 10 mm bit diameter. The regular spiral flute promotes consistent chip evacuation during through-hole and blind-hole operations. This bit is a heavy-duty designation, appropriate for production drilling environments where tool life and dimensional accuracy are priorities. Coolant-through capability is not included in this design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt steel construction with gold finish for heat resistance and extended tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry walking and lowers thrust force requirements\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration improves chip flow and reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and CNC holders\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and NAS 907 Type J standards for dimensional and performance consistency\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute with 2 flutes for stable chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks and CNC tool holders accepting a 10 mm straight-cylindrical shank.

Ensure the shank is fully seated and the chuck is properly tightened before operation. Appropriate cutting fluid or coolant application at the workpiece is recommended when drilling titanium or other hard metals to manage heat buildup, even though this bit does not feature internal coolant-through channels. Inspect the cutting edges before each use and replace when wear affects dimensional tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 10 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 133 mm (5.236 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 87 mm (3.425 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 46 mm (1.811 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm (0.3937 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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Gold\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 550\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 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\u003eWeight\u003c\/strong\u003e: 0.03 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: 46488\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51727097856306,"sku":"46488","price":108.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e18f3a73fcc1e869d3fccf79cdc8be4_4c134632-01f6-4ce3-8992-848867320605.jpg?v=1788673270","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-46488-cobalt-jobber-drill-bit-10-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
