Built from high speed steel with an oxide coating, this bit is engineered for heavy-duty cutting performance in demanding shop and field applications. The 135-degree split point reduces walking on entry and requires no center punch on most materials. With a regular spiral flute and tapered web configuration, the 45710 maintains chip clearance and cutting efficiency through the full depth of the bore. Licensed HVAC, plumbing, electrical, and mechanical trades rely on this size for pilot holes, tap drilling, and precision through-holes in metal components.\u003c\/p\u003e\n\u003cp\u003eThe 45710 is designed for use on cast iron, stainless steel, and carbon steel workpieces, making it a practical choice for commercial and residential mechanical installations where ferrous materials are common. The straight-cylindrical shank seats securely in standard 3-jaw drill chucks. The overall length of 2.375 inches and flute length of 1.375 inches suit typical jobber-range drilling tasks on panel knockouts, pipe flanges, brackets, and structural steel members. This bit conforms to NAS 907 Type B standards, indicating dimensional and performance requirements appropriate for industrial and trade use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering starts and reduced thrust on entry\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide coating for wear resistance and lubricity\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design promotes chip evacuation and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for standard CW drill press and hand drill operation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B specification for heavy-duty industrial service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for drilling cast iron, stainless steel, and steel workpieces. Fits any standard 3-jaw drill chuck accepting a 0.0980-inch straight shank. Suitable for use with benchtop drill presses, magnetic drills, and corded or cordless hand drills operating at appropriate RPM for the bit diameter and workpiece material.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSelect spindle speed appropriate for a 0.0980-inch bit diameter and the specific workpiece material before drilling; higher RPM is generally required for smaller diameters in steel. Secure the workpiece firmly before starting the cut to prevent the bit from walking at breakthrough. Apply a suitable cutting fluid when drilling stainless steel or cast iron to extend bit life and reduce heat. Always wear eye protection and ensure the chuck key is removed before powering the drill.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0980 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\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 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: 0.0980 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0000 inches\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\u003eMaterial\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150ASP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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: 0.0045 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: 45710\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51731000492338,"sku":"45710","price":32.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/782460eef0061e5342807dea23a26913_7f48283c-19eb-4626-8bae-f9c102df4f75.jpg?v=1788725671","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-45710-jobber-length-drill-bit-size-40-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
