Built to Series 120X specifications, this bit features a 0.7344-inch diameter with a 118-degree notched point angle and an oxide finish for improved lubricity and wear resistance. The spiral flute geometry is a regular right-hand cut with web thinning applied to reduce thrust and ease penetration. At 12 inches overall length with a 9-inch flute length, this bit gives machinists and fabricators the reach needed for deep-hole work in production and maintenance settings.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling cast iron and steel in applications that require extended reach beyond what jobber-length or screw-machine-length bits provide. Typical use cases include structural fabrication, heavy equipment repair, and industrial maintenance where hole depth or workpiece geometry demands a longer tool. The straight-cylindrical shank at 0.7344 inches in diameter and 3 inches in length seats securely in standard drill chucks and milling machine spindles. The tapered web configuration adds rigidity along the full flute length to reduce deflection during deep-hole passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.7344-inch diameter with a diameter tolerance of +0.0000 to -0.0012 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003e118-degree notched point angle reduces walking and improves self-centering on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003e9-inch flute length and 12-inch overall length for long-reach drilling where standard bits fall short\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles cast iron and steel at production feed and speed rates\u003c\/li\u003e\n  \u003cli\u003eOxide finish improves lubricity and surface hardness compared to bright finish HSS\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design lowers cutting thrust and aids chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003e2-flute right-hand spiral with regular helix suits general-purpose drilling in ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron and steel workpieces as an OEM-style general-purpose extra length drill bit in the CHICAGO-LATROBE Series 120X.

Secure the straight shank firmly in a properly sized chuck before operation to prevent runout. Use appropriate cutting fluid for cast iron and steel to manage heat and extend tool life. Inspect the cutting edges and web area before each use and replace the bit 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\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.7344 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.7344 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Notched\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: Spiral, Regular Helix\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Long Reach Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 120X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: California Prop 65\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: 50654\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51728097050930,"sku":"50654","price":141.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a9d9c629d17e1563f51ca8c920fc284_890ef688-8e84-473e-bf9b-4bf45d4b2edc.jpg?v=1788687893","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-50654-extra-length-drill-bit-0-7344-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
