Built from M42 cobalt high-speed steel with a black oxide finish, this bit delivers heat and wear resistance in demanding production environments. The 135-degree split point promotes self-centering on entry and reduces the thrust force needed to start a hole. With a flute length of 4.25 inches and an overall length of 6.75 inches, the taper length profile reaches deeper than a jobber bit while maintaining rigidity. Machinists and maintenance tradespeople rely on this geometry for consistent hole quality in tough materials.\u003c\/p\u003e\n\u003cp\u003eThe 44823 is suited for drilling cast iron, high-tensile steel, Inconel, manganese steel, and titanium. These are materials commonly encountered in industrial maintenance, fabrication shops, aerospace component work, and heavy equipment repair. The straight cylindrical shank fits standard drill chucks and CNC machine spindles. The spiral flute with regular spiral type clears chips efficiently during through-hole and deep drilling operations. The web-thinned, tapered web configuration reduces cutting resistance and helps maintain point integrity under load.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for extended tool life in hard and exotic alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point is self-centering and reduces walk on entry without a center punch\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish reduces friction and provides light corrosion resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting resistance and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003eTaper length body reaches deeper than standard jobber bits while maintaining stiffness\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute compatible with conventional drill press and CNC operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks and CNC spindles accepting a straight cylindrical shank.

Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Apply appropriate cutting fluid for the material being drilled, particularly when working with Inconel or titanium, to manage heat buildup and extend tool life. Inspect the cutting edges before each use and remove the bit from service if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 520\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 23\/64 inches (0.3594 inches)\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3594 inches (9.13 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black Oxide\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 Application\u003c\/strong\u003e: Cast Iron, High-Tensile Steel, Inconel, Manganese Steel, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter 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\u003eThreaded Shank\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1532 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: 44823\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51740185428274,"sku":"44823","price":49.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c3f8d983f5765920e44832087e405cc_256c571f-68b0-4da5-8438-28a90d323830.jpg?v=1788823290","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-44823-taper-length-drill-bit-23-64-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
