Built from high-speed steel with a bright uncoated finish, this bit features a 135-degree split point and web-thinned geometry that reduces thrust and improves self-centering on contact. With an overall length of 1-11\/16 inches and a 3\/4-inch flute length, the short screw machine profile provides rigidity and reduced deflection in drill press, CNC turret, and automatic screw machine operations. The straight-cylindrical shank measures 0.0785 inches in diameter and seats securely in standard chucks and collets.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling alloy steel and aluminum in tight-tolerance production environments. The screw machine length format makes it a common choice for turret lathes, multi-spindle machines, and bench drill presses where a standard jobber-length bit would be too long or too flexible. The 0.0785-inch decimal diameter corresponds to wire gauge No. 47, placing it in the small-diameter range appropriate for tapped hole prep, pilot holes, and precision clearance drilling in ferrous and non-ferrous workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge No. 47 diameter — 0.0785 inches decimal equivalent\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces entry thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction rated for heavy-duty service\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (1-11\/16 inches OAL) provides rigidity in production setups\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for use with cutting fluids on alloy and aluminum stock\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and NAS 907 Type C specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard production consumable for any setup requiring a wire gauge No. 47 screw machine length drill bit with a straight-cylindrical shank in standard chucks, collets, or turret tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and tool-and-die professionals in machine shop environments. Verify chuck or collet size matches the 0.0785-inch shank diameter before seating the bit. Power down and de-energize the machine before changing tooling per standard lockout\/tagout procedure. At this diameter, use appropriate cutting fluid and controlled feed rates to avoid bit breakage — do not force-feed small-diameter bits.\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: No. 47\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, 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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3\/4 inches (0.7500 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 Diameter\u003c\/strong\u003e: 0.0785 inches\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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy, Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, NAS 907 Type C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C70351\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51692886065458,"sku":"C70351","price":43.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65d59c5d84d088f5fd5069571a2a0a7a_394f0529-c5c6-44ed-9c69-bcefc698d799.jpg?v=1788304508","url":"https:\/\/voomisupply.com\/products\/cleveland-c70351-no-47-hss-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
