At 10 inches overall length with a 7.5-inch spiral flute and a 0.1562-inch diameter, this bit handles deep-hole work in tight or deep workpiece setups. The oxide finish provides moderate lubricity and surface protection. The right-hand cutting, two-flute spiral design with a 118-degree notched point and web-thinned, tapered web geometry reduces entry force and helps maintain accuracy through the cut. Licensed tradespeople and machinists working in fabrication, maintenance, and mechanical contracting reach for this bit when access depth is the limiting factor.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling into cast iron and steel in applications that require extended reach beyond a standard jobber-length bit. Typical scenarios include deep-cavity work, through-bolt clearance drilling in structural assemblies, and mechanical or electrical rough-in work where an obstacle or fixture prevents a short bit from seating fully in the chuck. The Series 120X designation indicates this is a purpose-built extra length line rather than a jobber bit with an extended shank, meaning the flute geometry is optimized for the full working length.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.1562-inch diameter with a diameter tolerance of +0.0000 to -0.0007 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003e10-inch overall length and 7.5-inch flute length for deep-reach drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree notched point with web thinning reduces thrust and improves chip clearance\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide finish for use in cast iron and steel\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.1562 inches diameter fits standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eRight-hand, two-flute regular spiral design for general purpose metal drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks accepting a 0.1562-inch straight-cylindrical shank.

Secure the shank fully and evenly in the chuck before operation to prevent runout across the extended length. Use appropriate cutting fluid or coolant for steel workpieces to manage heat buildup given the extended flute length. Inspect the bit for deflection or chatter during use, as the increased length-to-diameter ratio makes rigidity of the workpiece setup critical.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1562 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1562 inches (3.97 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 5 inches (63.50 mm)\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\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\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\u003eTool Application\u003c\/strong\u003e: Long Reach Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 120X\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\u003eStandards\u003c\/strong\u003e: California Proposition 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: 50717\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51731979206962,"sku":"50717","price":44.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a9d9c629d17e1563f51ca8c920fc284_00fa3031-881c-4853-94a2-6833cb814635.jpg?v=1788737549","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-50717-extra-length-drill-bit-hss-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
