Built from high speed steel with an oxide coating, it carries a No. 47 wire-gauge designation and a decimal diameter of 0.0785 inches. The 135-degree split point reduces walking and decreases thrust requirements at entry, making it well suited for production and maintenance drilling. The web-thinned, tapered web design keeps cutting efficiency high across a range of material hardnesses. Overall length is 2 inches with a 1-inch flute length. This bit is rated heavy duty and meets NAS 907 Type B standards. Licensed HVAC, mechanical, and general trade technicians as well as machinists and maintenance professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThe 45717 is built for drilling cast iron, stainless steel, and carbon steel. Its straight-cylindrical shank seats in standard drill chucks without special tooling. The 2-flute spiral design evacuates chips efficiently in deep-hole and cross-drilling applications common in mechanical rooms, fabrication shops, and field service work. The Series 150ASP designation places it in Chicago-Latrobe's heavy-duty jobber line, intended for continuous production use as well as demanding intermittent service tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 47 wire size, 0.0785-inch decimal diameter with a tight tolerance of -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and minimizes bit walking on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web improves cutting efficiency in cast iron and stainless steel\u003c\/li\u003e\n  \u003cli\u003eOxide coating provides lubricity and basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated heavy duty under NAS 907 Type B\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks; no adapter required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy-duty OEM-style replacement or production-use jobber bit for applications requiring a No. 47 wire-gauge diameter in cast iron, stainless steel, and carbon steel; compatible with any standard drill chuck accepting a 0.0785-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this bit should be performed by qualified machinists, mechanical technicians, or trade professionals familiar with drill press or hand-drill operation. Always secure the workpiece and power down or unplug the drilling tool before changing bits. Confirm chuck tightness before initiating a cut. Do not exceed the rated speed range for the material being drilled, and use appropriate cutting fluid when drilling stainless steel or hardened steel to prevent premature bit wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 47\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0785 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 Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0785 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150ASP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0027 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: 45717\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51753684140338,"sku":"45717","price":32.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/782460eef0061e5342807dea23a26913_f3ac9478-0bf3-4267-a054-c8a257493eb6.jpg?v=1788939445","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-45717-jobber-drill-bit-no-47-hss-135","provider":"Voomi Supply","version":"1.0","type":"link"}
