Built from M42 cobalt high-speed steel and coated with titanium nitride (TiN), it delivers extended tool life and reduced heat buildup when cutting hard or abrasive materials. The 135-degree split point reduces walking on entry and requires less thrust force to start a hole. At 4-7\/8 inches overall length with a 3-1\/2 inch flute length, this is a standard jobber-length geometry suited for general-purpose drilling in a wide range of setups. It is a Series 2550 heavy-duty bit built to DIN 338 and NAS 907 Type J standards.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for drilling stainless steel and steel where heat resistance and edge retention are critical. It fits the work patterns of maintenance machinists, pipefitters, fabricators, and metalworking tradespeople who encounter interrupted cuts, scale, or work-hardened surfaces. The straight-cylindrical shank seats in standard drill chucks without modification, making it compatible with common hand drills, drill presses, and CNC setups. The right-hand spiral flute clears chips efficiently during through-hole drilling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for high heat resistance and durability in hard metals\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating extends cutting life and reduces friction\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates center-punch requirements on most metals\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration improves chip evacuation and lowers cutting resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute with 2-flute geometry for clean chip clearance\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and NAS 907 Type J specifications for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy-duty jobber-length drill bit for use in stainless steel and steel applications.

Secure the straight shank firmly in the chuck before operation and verify the bit is centered and seated before applying feed force. Use appropriate cutting fluid when drilling stainless steel to manage heat and prolong edge life. Inspect the cutting edge for wear before each use and replace when the point shows chipping or heat discoloration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eOverall Length\u003c\/strong\u003e: 4-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 23\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3750 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 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: M42 Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2550\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\u003eCoolant Through\u003c\/strong\u003e: No\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: 54065\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51752717582642,"sku":"54065","price":32.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8760fb961b342b42f78a3d4e3b3252fb.jpg?v=1788929913","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-54065-cobalt-drill-bit-23-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
